When Francisco Rodriguez came to the New York Mets, I thought he was in for a rude awakening. First, he'd be on a much bigger stage than in Anaheim, and second, he was now in the same bullpen as J.J. Putz -- a bona fide Major League closer that could eat into K-Rod's ninth-inning duties should he struggle. I also felt that K-Rod was a bit of an injury risk, largely because of his jerky motion and slight frame. But here we are, over two months into the season, Putz is on the DL, and K-Rod is looking sharp as ever -- mowing down batters on the world's biggest stage.

Aside from his notable 0.98 WHIP and .153 BAA, Rodriguez has some bizarre batted ball splits. His GB/FB rate of 0.51 is the lowest (by far) of his career, and 20 percent of batted balls are infield fly balls (IFFB%, or essentially, pop-ups). I know we all analyze numbers like mad in this business, and constantly look for ways to explain that a low BABIP is a terrible thing (his is also quite low at .229), but I can't figure out how inducing lots of pop-ups is a bad thing for a closing pitcher. Pop-ups aren't usually a matter of luck, since even a perfect swing -- from a timing standpoint -- yields a line-drive, a moon shot, or a ball fouled directly back and out of play. Pop-ups are usually induced by a combination of a batter's poor timing and a pitch's sharp movement, just like broken bats. In only two seasons of Mariano Rivera's career, 2004 and 2008, did he post an incredibly high IFFB%. In these seasons, two of his best statistically, his IFFB% was a preposterous 26.2 and 24.5, while his BABIP was .285 and .234. I'd say there's a correlative link.

Sure, K-Rod will get hit a little more as his BABIP creeps upward during the season, but I'm willing to gamble that he's made an adjustment to induce more pop-ups by getting in on the hands of hitters more effectively -- and that's a great approach to have as a closing pitcher.

Ryan Madson, PHI 2-for-3 (67%), 13 HLDs, 28.1 IP, 31 Ks, 2.22 ERA, 1.06 WHIP Next in line: J.C. Romero Third in line: Chad Durbin

Ryan Madson has three good pitches (mid-90s fastball, low 90s cutter, low 80s change), and he's produced a comparably low Z-contact rate (78.2%) this season. If Lidge misses extended time, he could have unrivaled value on the waiver wire. George Sherrill finally makes his transition off the fence based on his unanticipated success in a closing role. It's his job to lose. Jose Valverde appears ready to assume closing duties and gets a promotion here. Just when I go saying something nice about Fernando Rodney, the 32-year-old has a meltdown, albeit one probably brought on by overwork (five appearances in six days). Huston Street continues to impress, and his peripherals (3.57 K/BB, 9.25 K/9, 1.07 WHIP) bode well for him maintaining his job. Scott Downs has a stronghold on the closer job in Toronto, and David Aardsma lost a threat when it was revealed Brandon Morrow would be converted to a starter once again. Morrow is in Tacoma and will work his arm up in Triple-A before re-joining the big club.

Brad Lidge, PHI: Sprained right knee We're not sure if the knee is truly sprained, or if something more is wrong after the Phillies revealed he's had inflammation all year. For now, he's on the 15-day DL retroactive to June 7, but GM Ruben Amaro, Jr. said he won't be activated until the joint is healthy. Ryan Madson takes over as the Phils' closer.

Chad Qualls, ARI: Forearm soreness/stiffness According to the Arizona Republic, Qualls doesn't feel too confident about having a healthy arm, describing his prospects of his returning to full strength as "a grind." A DL stint is possible, and might be what Qualls owners need for him to regain some of the dominance he displayed early on in the season. Tony Pena will see the bulk of save opportunities in his absence.

Frank Francisco, TEX: Shoulder tightness Francisco, like Qualls, was off to a fabulous start before developing arm issues, this time in the shoulder. The guy's BAA is currently a devastating .157, but that's a number that will invariably escalate if he tries to rush back. A stint on the retroactive DL could be just what he needs. C.J. Wilson and Eddie Guardado will split the save chances.

Troy Percival, TB: Right shoulder tendonitis He probably won't be ready for some time, although for now, retirement seems to be out.

Joey Devine, OAK: Elbow surgery Devine underwent Tommy John surgery and is out for the remainder of 2009.

Mike González, ATL 8-for-11 (73%), 27 IP, 35 Ks, 2.67 ERA, 1.26 WHIP Next in line: Rafael Soriano Third in line: Peter Moylan

Andrew Bailey, OAK 5-for-8 (63%), 37.1 IP, 44 Ks, 1.93 ERA, 0.91 WHIP Next in line: Brad Ziegler Third in line: Michael Wuertz

Mike MacDougal, WAS 0-for-0 (N/A%), 4.2 IP, 3 Ks, 0.00 ERA, 1.29 WHIP Next in line: Joe Beimel Third in line: Julian Tavarez

J.P. Howell, TB 2-for-7 (29%), 4 HLDs, 30 IP, 37 Ks, 2.10 ERA, 1.13 WHIP Next in line: Dan Wheeler/Randy Choate Third in line: Grant Balfour/ Joe Nelson

Mike MacDougal takes over as the Nationals closer-of-the-moment, and it appears Joel Hanrahan has lost the job for good. Don't be swindled by MacDougal's NL numbers -- he put up atrocious stats in the AL while he was still with the White Sox (12.46 ERA, 3.23 WHIP, .389 BAA, 7 BB, 3 K in 4.1 IP). He might be good for an occasional save, but don't look for his conversion rate to be much above 75 percent. The situation in Tampa Bay has become much like the Nats' -- with a new go-to-guy in the ninth every week. Perhaps J.P. Howell provides the best opportunity to hold down the job, since his peripherals (3.08 K/BB, 11.10 K/9, .202 BAA) are the most inspiring out of the Rays' bullpen. Andrew Bailey continues his impressive rookie run and seems to have completely wrested the job from Brad Ziegler, albeit without a formal announcement.
