Billy Wagner’s Dominance Gives Him a Surprisingly Strong Hall of Fame Case

Few closers were as dominant as Billy Wagner in his prime, but did the fireballing lefty log enough innings to merit a Cooperstown plaque?

The following article is part of my ongoing look at the candidates on the BBWAA 2018 Hall of Fame ballot. Originally written for the 2016 election, it has been updated to reflect it has been updated to reflect recent voting results as well as additional research. For a detailed introduction to this year's ballot, please see here. For an introduction to JAWS, see here.

Billy Wagner was the ultimate underdog. Undersized and coming from both a broken home and an impoverished rural background, he channeled his frustrations into throwing incredibly hard—with his left hand, despite being a natural righty (he broke his right arm twice as a child). Scouts overlooked him because he wasn't anywhere close to six feet tall, but they couldn’t disregard his dominance of collegiate hitters using a mid-90s fastball. The Astros made him a first-round pick, and once he was converted to a relief role, his velocity went even higher.

Thanks to outstanding lower-body strength, coordination and extraordinary range of motion, the 5' 10" Wagner was able to reach 100 mph with consistency—159 times in 2003, according to The Bill James Handbook—during the first part of his career. With an arsenal complemented by a high-80s slider learned from teammate (and 2018 ballot-mate) Brad Lidge, he kept blowing the ball by hitters into his late 30s to such an extent that he owns the record for the highest strikeout rate of any pitcher with at least 800 innings. He was still dominant when he walked away from the game following the 2010 season, fresh off a career-best ERA.

Lacking the longevity of fellow 2016 Hall of Fame ballot newcomer Trevor Hoffman, Wagner never set any saves records or even led his league once, and his innings total is well below those of every enshrined reliever. Hoffman's status as the former all-time saves leader helped him net 67.3% in his first ballot appearance in 2016, and 74.0% in 2017; his election is inevitable. But Wagner, who created similar value in his career, has major hurdles to surmount after receiving just 10.5% and 10.2% in his two years on the ballot. Nonetheless, his advantages over Hoffman—and virtually every other reliever in history when it comes to rate stats—provide a compelling reason to study his career more closely. Given how far he's come, who wants to bet against Billy Wags?


Career WAR

Peak WAR







Billy Wagner


















Wagner was born in Marion, Va., in 1971, into circumstances—as documented in a Sept. 20, 1999 Sports Illustrated profile by Michael Bamberger—that were hardly idyllic. Father William "Hotsey" Wagner, an all-county pitcher, married his 16-year-old bride, Yvonne Hall, on the day he graduated high school. Billy was born 13 months after they wed; two weeks later, Hotsey left for Saigon, where he spent nine months monitoring the urinalyses of U.S. soldiers about to return home from the Vietnam War. After he returned home, his marriage collapsed in 1976. Billy and his younger sister bounced around in the care of his divorced (and remarried, and re-divorced) parents and both sets of grandparents. Poverty was a constant; food stamps were an embarrassment; "[a] few crackers with peanut butter and a glass of water” was a typical breakfast.

While playing football at age seven, a friend fell on Wagner's right (throwing) arm and broke it; six weeks later, just after the cast was removed, he broke it again. During this time, Wagner learned to throw lefthanded, turning his baseball glove inside out and channeling his anger at his instability and grim surroundings into throwing a ball at the side of his maternal grandparents' house, doing it so hard that pieces of aluminum siding fell off. Finally, just before he turned 15, he went to live with Jack and Sally Lamie, his uncle and aunt, in Tannersville, 19 miles away. By that point, Billy had fallen a year behind in school due to his unstable home situation, but once coaches and administrators at Tazewell High School (the closest high school, an hour away) agreed that his throwing was a danger to his middle-school peers, they "socially promoted" him into high school.

While The Numbers Don't Always Support It, Trevor Hoffman Will Likely Secure a Hall of Fame Spot

Though he grew to just 5' 5" and 135 pounds in high school, Wagner starred as both a centerfielder and pitcher whose fastball could reach 86 mph. As a senior in 1990, he hit .451, stole 23 bases and struck out 116 in 46 innings with a 1.52 ERA. Scouts were put off by his size, so he followed cousin Jeff Lamie to Ferrum College, a Division III school, with the intention of playing football—until the coach saw him throw a baseball. At Ferrum, Wagner grew to 5' 9", gained 40 pounds and boosted his velocity to 93 mph. As a sophomore in 1992, he allowed nine hits in 51 innings and set an NCAA record with 19.1 strikeouts per nine. While dominating the collegiate Cape Cod League, he struck out the side in the league’s All-Star game without allowing a foul ball. The Astros chose him with the 12th pick in the 1993 draft.

By now 5' 10" and 170 pounds, Wagner began his professional career as a starter, battling control issues but whiffing more than a batter per inning at every stop and making Baseball America's Top 100 Prospects list in 1994 (78th), '95 (17th) and '96 (14th). In 1995, he posted a 2.89 ERA in hitter-friendly Double A and Triple A leagues, with 9.7 strikeouts per nine in 146 1/3 innings. All the more impressive was that his performance came amid tragedy, as his wife's father—who had emerged as a father figure in Wagner's life—and stepmother were brutally murdered in May, just days after Wagner had been added to the Astros' 40-man roster in anticipation of a late-season callup.

Wagner made his major league debut on Sept. 13, 1995 in Shea Stadium; mustering a fastball near 100 mph, he retired the Mets' Rico Brogna on a fly ball before being lifted for a pinch-hitter by Astros manager Terry Collins. After 12 starts for Triple A Tucson in 1996, the fire-balling Wagner, 24, joined the Astros' bullpen in early June and supplanted the injured Todd Jones as the team's closer after the All-Star break. He converted nine saves in 13 chances, finishing the year with 2.44 ERA and 11.7 strikeouts per nine (but 5.2 walks) in 51 2/3 innings. The Astros carried a 2 1/2-game division lead into September, but a 4–16 tailspin to start the month lost them the division and cost Collins his job.

Under new manager Larry Dierker and powered by the "Killer B's"—Jeff Bagwell and Craig Biggio—the Astros made the playoffs in each of the next three seasons, with Wagner emerging as one of the game's most dominant closers. He saved 23 games with a 2.85 ERA and 14.4 strikeouts per nine in 1997, setting a record for a pitcher with at least 50 innings. Despite missing more than three weeks in 1998 after taking a Kelly Stinnett line drive off his head, he topped that strikeout rate in each of the next two seasons and trimmed both his walk rate and ERA. In 1999, he whiffed 14.9 per nine and walked 2.8 en route to a 1.57 ERA with 39 saves in 74 2/3 innings. Not only did Wagner make his first All-Star team, but he also tied teammate Jose Lima for fourth in a particularly Houston-heavy Cy Young vote; ex-Astro Randy Johnson won, and Mike Hampton finished second. Wagner's 3.8 WAR led all National League relievers and nearly topped the 4.0 he had accumulated in the previous three seasons.

It was that September when Bamberger caught up with "the Astros' smaller-than-life closer" who "would tip the scales at his listed weight of 180 pounds only after a third helping of grits," exploring his difficult past in an attempt to find out, "Where does he get his heat?"

He throws fastball after fastball, one four-seamer after another, all in the A to A-plus range. The movement on his pitches is wicked. Batters speak of heaters that start at their heads and finish at the knees, on the outside corner of the plate. On Wagner you can guess fastball. (He throws only occasional sliders and changeups.) What you can't do is hit it.

…It is true that Wagner has superb mechanics, which is amazing when you consider that he is a natural righthander.… It is also true that he drives off the rubber as well as any pitcher since Tom Seaver; his legs are thick and heavy for a man of his otherwise ordinary physique. It is true that he has a remarkable ability to throw first-pitch strikes. But those facts alone do not begin to answer the question.

In February 1999, Wagner had signed a three-year, $10.1 million extension, covering his arbitration years. For as strong as his 1999 was, his 2000 was a near-total loss: Wagner struggled with his control in 27 2/3 innings before admitting he had been throwing in pain and undergoing season-ending surgery to repair a torn flexor tendon and remove scar tissue. With their bullpen a mess, the Astros sank to 72–90, but both Wagner and the team rebounded in 2001. Wagner made his second All-Star team, saved 39 games, whiffed 11.3 per nine and finished with 2.4 WAR, and the Astros won 93 games and their fourth NL Central title in five years. Alas, they were again ousted in the first round by the Braves, who had done so in 1997 and '99 as well.

Via both WAR and ERA, Wagner's performance continued to improve in 2002 and '03. In the latter season, his third All-Star campaign, he set career highs with 86 innings and 44 saves en route to a 1.78 ERA, 11.0 strikeouts per nine and 3.3 WAR, the last of which tied John Smoltz for second among NL relievers. On June 13, 2003, Wagner helped make baseball history when he closed out a combined no-hitter of six pitchers against the Yankees in the Bronx—the first time New York had been no-hit since 1958. Two pitches into the second inning, starter Roy Oswalt had to depart due to a groin injury; relievers Peter Munro, Kirk Saarloos, Lidge and Octavio Dotel carried the baton to Wagner, who struck out Jorge Posada and Bubba Trammell, then covered first base on Hideki Matsui’s game-ending groundout.

After missing the playoffs in 2002, the Astros battled with the Cubs for the NL Central title in '03, but a 3–6 record over the final nine games cost them a 1 1/2-game lead. While Wagner took one of those losses, it was only the second time over his final 36 appearances that he allowed a run. After the season, he criticized owner Drayton McLane for the team's failure to increase payroll to augment their rotation. "It's going to be a tape job," he said after the team's final game, looking to next season. "It's not like we're going out there and getting any marquee pitchers.”

Wagner would be proven quite wrong, but he had punched his ticket out of town. Owed $8 million for 2004 with a $9 million option for '05, he was traded to Philadelphia on Nov. 3 for a trio of pitchers (Ezequiel Astacio, Taylor Buchholz and Brandon Duckworth) who combined to deliver -3.5 WAR as Astros. Their sorry production was more than offset by Houston's marquee free-agent pitchers: Roger Clemens and Andy Pettitte, who helped the Astros reach the NLCS in 2004 and then the World Series in '05. "I just wish he'd done this when we were a game out last season," said Wagner of McLane’s spending.

Though he joined a team that was beginning to assemble the roster that would dominate the NL East from 2007 to '11, Wagner's two years in Philadelphia were less than fulfilling. Groin and rotator cuff strains cost him 2 1/2 months in 2004, limiting him to 48 1/3 innings. He rebounded with another All-Star season in 2005 (1.51 ERA, 38 saves, 2.7 WAR), but his mouth continued to make bigger headlines. Amid a 4–12 July skid, he criticized the team's intensity, saying that the Phillies quit when they fell behind and that "we ain’t got a chance to get there right now,” in reference to the postseason. While the Phillies finished with 88 wins under new manager Charlie Manuel, they fell one game short of the wild card and two short of the division title. Wagner spent the last third of the season in silence after receiving no support in a players-only meeting, then blasted his ex-teammates from afar departing. Years later, he lamented, "I learned a lot about criticism and how not to be a leader when I was traded … I began to turn into someone I didn't want to be."

Scott Rolen, a Defensive Wizard and Consistent Hitter, Presents a Strong Hall of Fame Case

A free agent for the first time, the 34-year-old Wagner landed a four-year, $43 million deal with the Mets and sparked an inter-borough controversy: His entry song, Metallica's "Enter Sandman," was already in use by the Yankees' Mariano Rivera, though Wagner’s 1996 adoption predated Rivera by three years. The song got a workout in Queens: Wagner saved 40 of the Mets' 97 wins as they claimed their first NL East title in 20 years. Accompanied by a typically low 2.24 ERA, Wagner's save total ranked second in the league, the highest he would ever finish, and his 11.7 strikeouts per nine was his highest mark since 1999.

He notched the first three saves of his postseason career as the Mets downed the Dodgers and won the NLCS opener against the Cardinals, but he took the loss in Game 2 by allowing three ninth-inning runs, then gave up two runs while protecting a 4–0 ninth-inning lead in Game 6. In Game 7, manager Willie Randolph left setup man Aaron Heilman in for his second inning of work in the ninth inning of a tie game; Wagner could only watch as Heilman served up a decisive two-run homer to Yadier Molina.

That was as close as Wagner ever got to a World Series. Though he pitched very well for most of 2007, saving 26 of his first 27 chances with a 1.28 ERA, he posted a 6.91 ERA from Aug. 21 onward, a span of 14 appearances. That Mets team gained infamy for blowing a seven-game lead with 17 games to go, losing out on a playoff spot on the season's final day, but Wagner's only blown save in that span came in a New York win. The team wound up outside the playoff picture on the final day in 2008 as well, in part because Wagner’s Aug. 2 forearm strain led to Tommy John surgery.

When the Mets signed Francisco Rodriguez to a three-year, $37 million deal that winter, the message was clear to the rehabbing Wagner. After making two appearances for the team, on Aug. 20 and 24, he waved his no-trade clause and was dealt to the Red Sox, who in turn promised not to pick up his $8 million option for 2010, granting Wagner complete freedom in choosing where to pitch the following season. He was strong in 15 appearances for Boston, striking out 22 in just 13 2/3 innings for a team that won the wild card but was swept out of the first round by the Angels.


In December 2009, Wagner signed a one-year, $7 million deal with Atlanta, and at 38, he pitched as well as ever, posting a career-low 1.43 ERA and striking out 13.5 per nine (his highest rate since 1999) in 69 1/3 innings en route to 2.4 WAR for yet another wild-card team that made a first-round exit. On June 25 against the Tigers, he struck out the side on 10 pitches and became the fifth pitcher to reach 400 saves in his career. Despite triggering a vesting option for 2011, Wagner followed through with a decision announced in May: He would retire at season's end to spend more time with his family. No pitcher has ever walked away from his career following a season of at least 50 innings with a lower ERA or a higher strikeout rate.

Talented and Tainted, Manny Ramirez Is One of the Hall of Fame's Most Challenging Cases

Wagner holds some other distinctions as well. Among pitchers with at least 800 innings, his strikeout rate—whether expressed as 11.9 per nine or as 33.2% of all batters faced—is the best in history by a comfortable margin. Yu Darvish’s 11.0 per nine and 29.0% are the next-closest marks, and with fewer than 500 innings under their belts, Craig Kimbrel (42.0%), Aroldis Chapman (41.4%) and Kenley Jansen (40.1%) are years away from overtaking him.

At the 800-inning level, Wagner's .187 opponent batting average is the lowest in history, 12 points lower than the next 20th- or 21st-century pitcher, Herb Score. Wagner's 0.998 WHIP just edges Rivera's 1.000 for second all-time behind dead-ball era hurler Addie Joss (0.968). Meanwhile, Rivera is the only post-1920 pitcher with a lower ERA (2.21) or higher ERA+ (205) than Wagner's 2.31 and 187. Among that same group, Clayton Kershaw and Sandy Koufax are the only pitchers with a FIP lower than Wagner's 2.73. Oh, and Wagner's 422 saves are fifth on the all-time list behind Rivera (652), Hoffman (601), ballot holdover Lee Smith (478) and John Franco (424).

Is that a Hall of Fame career? As I laid out in connection to the cases of Smith and Hoffman, with just five relievers in the Hall, it's difficult to say, particularly given the role’s evolution over the past half-century. Hoyt Wilhelm, Rollie Fingers and Goose Gossage were all multi-inning firemen who racked up higher innings totals than the ballot's current trio. Bruce Sutter worked multiple innings as well, though generally only when his team had a lead narrow enough to produce a save opportunity. Dennis Eckersley, who spent the first half of his career as a starter, became the model for the one-inning closer we know today. Even excluding Eckersley’s 3,285 2/3 innings, the other four averaged 1,702 innings, whereas Wagner threw only 903, well below even Hoffman’s 1,089 1/3. Wagner has more saves than any of the enshrined pitchers, but 87% of them were one-inning saves; only 9% were longer than an inning. As noted in discussing Hoffman's candidacy, the majority of the saves of Wilhelm, Fingers, Gossage and Sutter were longer than an inning, as were 27% of Eckersley's.

While one can certainly make the case that, based on rate stats, Wagner was more dominant than any of them, his shortfall of innings presents a problem when translating to a value measure such as WAR. That said, he was so much more dominant than Hoffman that the two are tied at 24.0 JAWS, with Hoffman’s slight edge in career WAR (28.4 to 28.1) offset by Wagner’s slight edge in peak (19.9 to 19.6). Either way, both are significantly below the standards at the position even if I exclude Eckersley. The other four pitchers averaged 35.0 career WAR, 25.7 peak WAR and 30.4 JAWS; as with Hoffman, there's no way to justify Wagner's inclusion in Cooperstown on the basis of those metrics.

That doesn't mean that it's game over for either closer, though. While the version of WAR used in JAWS features an adjustment for leverage—the quantitatively greater impact on winning and losing that a reliever has at the end of the ballgame than a starter does earlier—to help account for the degree of difficulty, it’s not the only way to measure reliever value. Win Probability Added (WPA) is a context-sensitive measure that accounts for the incremental increase (or decrease) in chances of winning produced in each plate appearance given the inning, score and base-out situation. For a reliever, a single-season WPA scales similarly to a single-season WAR, which is to say that it’s rare that one is worth more than three wins in a single year, by either measure. Wagner ranks a respectable seventh in WPA at 29.1, trailing Rivera (56.6), Hoffman (34.2) and three enshrined relievers (Gossage is third at 32.5, Eckersley fourth at 30.85), Wilhelm fifth at 30.84, Sutter 27th at 18.2 and Fingers 30th at 16.2). The average for the enshrined five is 25.7; Wagner is 3.4 wins above that.

Another way to view reliever value along these lines is to adjust WPA using a pitcher’s average leverage index (aLI) for a stat variably called situational wins or context-neutral wins (referred to as WPA/LI). Here Wagner ranks fifth all-time (note the discontinuity of rankings outside the top 10).

The average Hall of Fame reliever (this time including Eckersley) weighs in at 18.9, so Wagner is a bit shy, but not remarkably so. As with Hoffman, he also fares well via Nate Silver’s Goose Egg stat, a WPA alternative introduced last April at Five Thirty Eight. A Goose Egg (named after Gossage, the all-time leader with 677) is a scoreless inning in a late, high-leverage situation (seventh inning or later, score tied or ahead by no more than two runs, no runs or inherited runners allowed to score, and so on); a pitcher can get more than one in a game. Wagner’s 421 Goose Eggs is only 19th all-time, well below the 578 averaged by the five enshrines. That number is weighed down by Eckersley’s 352 with Broken Eggs (failures in Goose Egg situations) factored in, which creates a new replacement level baseline (Goose Wins Above Replacement, or GWAR). Wagner’s 37.0 GWAR is fourth behind Rivera’s 54.6, Hoffman’s 43.7 and Gossage’s 39.4. With Wilhelm ninth at 31.3, Sutter 12th at 30.3, Fingers 17th at 25.3 and Eckesley 32nd at 20.8, the five enshrined average a total of 29.6.

Roger Clemens, Arguably the Greatest Pitcher of All-Time, Is Trending Toward Hall of Fame Induction

All of those leverage-based measures provide a much stronger basis for voting for Wagner than JAWS. That goes doubly when taken alongside his other accomplishments and overlooking his unsightly 10.03 ERA in 11 2/3 postseason innings for teams that were generally in the midst of being steamrolled.

Wagner faces an uphill battle to get to Cooperstown, having received just 10.5% of the vote in 2016, a lower debut percentage than any player elected by the writers since they returned to annual balloting in 1966 With 10.2% in 2017, he’s in danger of slipping below the 5.0% threshold to remain on the ballot in any given year. As I’ve said in each previous cycle, I’m not ready to close the door on him. While JAWS guides my process, my concerns over its handling of relievers has led me to remain particularly open-minded in this area over the years, seeking alternative ways to evaluate them. At the moment, I wouldn’t bump a JAWS-approved candidate off my ballot to make room for him, but I’m not ready to dismiss the possibility that Wagner merits a spot, as his dominance in so many categories is difficult to ignore.
