Trade deadline another lesson in not overreacting to rumors

This trade deadline is the reason you don't overreact to rumors and hearsay in fantasy. Most of it winds up being random noise and nothing to be worry about.

There weren't impact players switching leagues. There is really just one: Ubaldo Jimenez is a surprisingly great addition to the AL player pool.

If you dealt Heath Bell anticipating the Padres to deal him, you're left gasping because he will still be saving games for the Padres -- at least until the August waivers trade deadline.

And you picked up Mike Adams, hoping he would become a closer. Nope. He is still a setup man, now in a park tougher on pitchers.

It is yet another lesson to knowing the rumors, hearing the rumors, but not overreacting to them. We break down all the deals that went down over this busy weekend, starting from the top down:

• Cleveland Indians get: SP Ubaldo Jimenez

Jimenez won't have to pitch in Coors Field any longer, but he also won't be getting great run support either. Jimenez's ERA was over two runs better away from home and his batting-average against is .183 on the road (.310 at home). Expect him to be closer to the ace you expected this season, but he still won't be a big-time winner. The Indians are a contender, but barely.

• Colorado Rockies get: SP Drew Pomeranz, SP Alex White, 1B Matt McBride and SP Joe Gardner

The Rockies get a pair of first-round picks in Pomeranz and White. Both could be in the Rockies rotation by the middle of next season and helping fantasy owners. They are outstanding options in keeper leagues, even having to pitch in Coors Field. McBride and Gardner aren't yet projectable for fantasy owners.

• Philadelphia Phillies get: OF Hunter Pence

The Phillies have a great ballpark and lineup to help Pence take a next big step into the fantasy elite among outfielders. He should be a multi-category threat who is going to prove to be a must-have in the season's final two months. It is rare to get a 28-year-old talent like this in his prime -- and to add him to a great lineup in a great hitter's park. This looks like a match made in heaven for Pence owners, especially the ones that were sweating out losing him to the AL.

• Houston Astros get: 1B Jonathan Singleton, SP Jarred Cosart and RP Josh Zeid

Cosart could be a rotation option for the Astros by the end of 2012, while Singleton gives the Astros a fallback option long term if Brett Wallace never pans out. Zeid is merely a middle reliever. None of these players are going to impact fantasy significantly for a few years.

• Boston Red Sox get: SP Erik Bedard, RP Josh Fields

Bedard gets a team with run support for the first time in his career. The question is whether he can stay healthy. If he can, fantasy owners have a potential winner on their hands. Bedard is still available in 20 percent of leagues, so there is a great opportunity to get something for nothing off the waiver wire in some smaller mixed leagues.

• Seattle Mariners get: OF Trayvon Robinson, OF Chih-Hsien Chiang

The Mariners get a pair of 23-year-old outfield prospects with good pop. Robinson (.293, 26 homers in Triple-A) strikes out way too much, but he could be up to contribute for Seattle and AL-only leagues soon. Chiang looks like a September call-up.

• Los Angeles Dodgers get: C Tim Federowicz, SP Stephen Fife and RP Juan Rodriguez

Fife has a chance to develop into a back-end starter, but none of these players figure to impact fantasy this year -- or even next.

• Atlanta Braves get: OF Michael Bourn

Bourn gets a little better supporting cast with the Braves, so consider him slight more intriguing. He remains a must-start outfielder regardless. The real beneficiaries here are the RBI men behind Bourn in the Braves' lineup, like Martin Prado, Chipper Jones and the resurgent Dan Uggla.

• Houston Astros get: OF Jordan Schafer, RP Juan Abreu, SP Paul Clemens and SP Brett Oberholtzer

Clemens and Oberholtzer are decent starting pitching prospects that give the Astros quantity. The Astros pretty well here, selling high on Bourn, but none of these players are going to significantly impact fantasy. Schafer is merely an NL-only Rotisserie player, but he will at least be allowed to go out there and play every day as the Astros evaluate him.

• Detroit Tigers get: SP Doug Fister, RP David Pauley

Fister stays in a pitcher's park with the move to Detroit, but he gets a contender with a decent offense to support him now. Consider him far more trustworthy in standard mixed fantasy leagues now. Pauley is merely a reliever and not fantasy viable.

• Seattle Mariners get: 3B Francisco Martinez, OF Casper Wells, SP Charlie Furbush and a player to be named

Martinez is a potential gem down the road, and Wells can help AL-only owners right now, but Furbush is the impact pick-up in the short term. He has a future as a solid rotation starter and he should get his chance right away in Seattle. That is a great pitcher's park to build up in, but he just has limited fantasy value because the Mariners just don't score any runs.

• St. Louis Cardinals get: SS Rafael Furcal

Furcal's numbers are brutal right now, but a change of scenery and entering a pennant race could ignite him again. He has had streaky months in the past. It is a good time to buy if you need a shortstop, say if you lost a Stephen Drew.

• Los Angeles Dodgers get: OF Alex Castellanos

Castellanos (.319, 19 homers, 10 steals) has good numbers in Double-A and could be a September call-up, but he doesn't yet project to be a big-league regular.

• Pittsburgh Pirates get: 1B Derrek Lee

Lee is clearly past his prime, but he still has pop and the ability to post some hot streaks. Like Furcal, perhaps a pennant race can get him rolling again and make him worthwhile to mixed-league owners.

• Baltimore Orioles get: 1B Aaron Baker

Baker is your typical slugging minor-league who strikes out too much and might not be able to handle pitchers in the highest levels. Don't consider him fantasy viable this year or next.

• Pittsburgh Pirates get: OF Ryan Ludwick

Ludwick hasn't been a true mixed-league outfielder in years -- mostly because cavernous Petco Park has ruined him. He gets a reprieve down the stretch in Pittsburgh. He can add pop to the Pirates in a pennant race with Lee.

• San Diego Padres get: Player to be named or cash

• Oakland A's get: 1B Brandon Allen and RP Jordan Norberto

The A's need pop and they get it in Allen, but that pop comes with loads of strikeouts and inconsistency. Allen can impact AL-only Rotisserie leagues initially and maybe the change of scenery can make him a streaky slugger worth using in mixed formats from time to time. Noberto is merely a situational lefty.

• Arizona Diamondbacks get: RP Brad Zeigler

Zeigler was never able to duplicate that half season as a closer back in 2008. He revealed himself to be murder on righties and needing relief against lefties. He is going to remain a situational reliever in Arizona.

• San Francisco Giants get: 2B Orlando Cabrera

Cabrera is a winner, even if he doesn't provide much offense anymore for fantasy purposes. He is at least a warm body available for NL-only Rotisserie leagues now. He could get some time at shortstop, too.

• Cleveland Indians get: OF Thomas Neal

Neal was a prospect, but outside of the California League, he just doesn't show enough pop or speed to be a real keeper-worthy option for fantasy owners. Consider him a back-up outfielder.

• Texas Rangers get: RP Koji Uehara

We figured Uehara could be a good closer for the Orioles if they dealt Kevin Gregg. Instead, Uehara is going to be a knockout reliever as a setup man. It doesn't do much in leagues that don't use true middle men, but Uehara and Mike Adams are both going to make the Rangers' starters and closer more effective for fantasy owners.

• Baltimore Orioles get: 3B Chris Davis, SP Tommy Hunter

The Orioles get a starting infielder in the mold of their Mark Reynolds -- first or third -- and a rotation option in Hunter. It is great return for a mid-30s reliever they didn't think enough of to make a starter or a closer on a non-contender. Davis has the chance to be a big-time sleeper for deeper formats, especially AL-only. He could be very Reynolds-like with his homers and strikeouts. Davis will finally get a starting job without being placed on the Triple-A shuttle. Hunter might become a starter for the O's, but their non-contender likely won't make him enough of a winner to be useful outside of deeper AL-only leagues.

• Texas Rangers get: RP Mike Adams

Adams changes leagues and doesn't get the chance to close he could have gotten in San Diego if Heath Bell had been dealt. It makes him merely a middle relief option for the deepest of leagues that use true middle men. It will be hard to maintain that pristine ERA and WHIP he had in San Diego, though.

• San Diego Padres get: SP Robbie Erlin and SP Joe Wieland

The Padres get a pair of starting pitcher prospects who are ridiculously good strike-throwers. They lack a plus fastball, but San Diego's pitchers park should eventually suit them. They won't impact fantasy for a couple of years, though, since they are still in their early 20s.

• Arizona Diamondbacks get: SP Jason Marquis

Marquis has enjoyed a rebound season and he could be slightly better with a contender in Arizona, which can get him more run support than the Nats ever could. He loses the comfort of that Nats pitcher's park for that hitter-friendly dry air in Arizona.

• Washington Nationals get: INF Zach Walters

Walters is too low in the minors to yet be a projectable prospect for fantasy owners. He might not be a starter once he arrives. Don't consider him all that viable as a long-term keeper.

• Boston Red Sox get: 2B Mike Aviles

Aviles is versatile and can hit. He fits well in the Red Sox mold, but his inability to play any infield position with consistency defensively is going to keep him from impacting leagues outside of the deepest AL-only formats.

• Kansas City Royals get: 3B Yamaico Navarro and RP Kendal Volz

The Royals get a potential reserve infielder and a reliever. Neither will have fantasy value -- perhaps at any time in their careers.

• Cleveland Indians get: OF Kosuke Fukudome

Fukudome is merely a reserve outfielder for the deepest of AL-only leagues -- with or without regular starts.

• Chicago Cubs get: RP Carlton Smith and OF Abner Abreu

The Cubs get something for the erstwhile Japanese import, surprisingly. They didn't get anything fantasy owners need to be concerned about. Smith is a middle reliever, while Abreu is a free-swinging Class A outfielder.

• Milwaukee Brewers get: 2B Jerry Hairston

Hairston is versatile and could get regular at-bats at second base for the Brewers. It makes him a valuable reserve in NL-only Rotisserie formats.

• Washington Nationals get: OF Erik Komatsu

A 23-year-old outfielder in low Class A with a possible future as a reserve? Yeah, ignore him.
