Best and Worst Free Agent Signings NL

Let's look at the best and worst free agent signings in the National League by position at this point (guys could have been resigned by original team, just had to be a free agent this past offseason):

• Catcher - Best: Dave Ross. Worst: Ivan Rodriguez. Dave Ross (.293/.396/.573 with 6 HR in 82 ABs) combines with Brian McCann to have the best hitting catching duo in the majors. Ivan Rodriguez has 226 PA and has walked a grand total of 9 times, accumulating a .249/.280/.394 line. The guy is not a good hitter anymore.
• First base - Best: Tony Clark. Worst: Rich Aurilia. Tony Clark is once again proving to be a great bench asset. The guy is supposedly tremendous in the clubhouse and has an .828 OPS and 4 HRs in 54 PAs. Rich Aurilia is not really a first baseman, but truly shouldn't even be a major leaguer anymore. He has 105 PAs and has rung up and awful .211/.267/.263 line. Giving ABs to him is just a waste of an AB.
• Second base - Best: Orlando Hudson/Craig Counsell. Worst: David Eckstein. Orlando Hudson and Craig Counsell both have identical .303/.371/.438 lines. How weird is that? O-dog has been a huge part of the Dodgers lineup minus Manny and Counsell has been a huge part of the Brewers lineup minus Rickie Weekes. Special mention to Felipe Lopez who was a good bargain bin pickup by the Diamondbacks. David Eckstein hasn't been bad, but I think gets tremendously overrated. Some have called him the team's MVP, but the guy has a .673 with 1 HR and 2 SB. Not exactly Adrian Gonzalez.
• Shortstop - Best: Alex Cora. Worst: Edgar Renteria/Rafael Furcal. This is not a good position for free agents. 37-year-old Juan Castro is the only above average hitter and he only has 55 ABs. Alex Cora has done a great job for the Mets in the field and in the clubhouse, so he gets the mention here. Edgar Renteria is one of the worst hitters out there with a .633 OPS, 2 HRs, and 4 SB in a decent hitters park (and he hasn't been good on defense in a while). Rafael Furcal screwed over the Braves and A's and I think they're both very, very glad not to have him. When he hasn't been hurt he's had an awful season and can't even steal bases anymore (4 SB, 4 CS). Special Mention needs to go out to two Ramons: Vazquez (.615 OPS) and Martinez (.396 OPS with 8 times on base in 44 PAs for the Mets).
• Third Base - Best: Casey Blake. Worst: Jerry Hairston/Juan Uribe. Casey Blake cost the Dodgers a good catching prospect but he's been worth the trouble. He's hitting in the middle of that Dodgers lineup and producing without Manny. Jerry Hairston has hit 7 HRs in one of the best hitting parks in the majors but has only managed a .249/.307/.394 line. Juan Uribe has 5 BB to 28 Ks.
• Outfield - Best: Manny Ramirez, Raul Ibanez, Adam Dunn. Worst: Jason Michaels and Milton Bradley. Manny was a tough one here to say if he was a boon or a bust. I'm going with the former. He was the MVP at the time of his suspension and his departure from the Dodgers not only inspired them to band together and play like a team, but saved the Dodgers a few million dollars that they can now use at the trade deadline to fix any holes before October. Raul Ibanez was the MVP before he got hurt and has been one of the best free agent signings in either league. Adam Dunn continues to rake and got passed over by way too many teams because he has high K numbers (but who cares if he gets on base and mashes like he does). Milton Bradley has not only been a total head case, injury prone and a "piece of shit" (as his manager describes him), but also has failed to produce. When the Indians traded for Jason Michaels back in the day, I thought it was a great move. But I don't know if was too lofty expectations or a PED drop-off, but this guy has lost his way. He's .179/.247/.299 for the Pirates.
• Starting Pitching - Best: Randy Wolf, Livan Hernandez. Worst: Oliver Perez, Jamie Moyer, Braden Looper. Stuck to three for worst, but could have added a few more in. Randy Wolf has been the most unheralded free agent pickup but he's been great for Joe Torre's Dodgers. Livan Hernandez has been everything the Mets needed: an inning eater who could rack up a few wins for them. His loss yesterday was a tough one as he held the Yanks to 3 runs in 7 innings. In fact, before last night Livan had only left one start without the lead since May 15th. After Johan Santana, Livan may be the best the Mets are offering right now. There were a lot of bad free agent pitching signings but Ollie Perez may be the worst since the Mets knew exactly what they were getting from him. If he really was injured, it was just ignorance on their part. Jamie Moyer can't be faulted because he's beyond old (46), but he has an ERA of 6.05 with 19 HR in 83.1 innings. Looper hasn't been much better (but could have been replaced by Jon Garland, Mike Hampton, or even Randy Johnson or Derek Lowe). Expected to help fill in for the loss of Ben Sheets, Looper is off to a rough start. 
• Relief Pitching - Best: Jeremy Affeldt, Arthur Rhodes, Dave Weathers, Ron Villone, Trever Miller, Julian Tavarez. Worst: Alan Embree, Kip Wells, Will Ohman. There are a LOT of good free agent pitchers signed last offseason. This list doesn't even have Joe Beimel or Bobby Howry who have both been very good. Affeldt was the first free agent signed and now you know why. His ERA+ is 274. He's given up as many earned runs as K-Rod this year. Arthur Rhodes and Dave Weathers have been great for Cincinatti. Rhodes has held opponents to an insane .161/.225/.258 line and an insane .863 WHIP. Weathers has been good too with a 2.45 ERA in 25.2 innings with a WHIP of 1.130. Ron Villone and Julian Tavarez have been the two Nats bright spots in the bullpen (though Beimel hasn't been bad) and Trever Miller is really tough to hit for St. Louis with a K/9 of 9.74 (higher than K-Rod). Will Ohman wanted a lot more money this offseason and settled for Los Angeles and hasn't proved he was worth any more with a 5.84 ERA, .979 OPS against and a 1.622 WHIP. Kip Wells is a part of the problem with the Nats bullpen with a 6.49 ERA and Alan Embree has been nothing short of  disaster with a 7.08 ERA, 1.770 WHIP, and only 4.43 K/9.
• Closer - Best: Francisco Rodriguez, Trevor Hoffman, LaTroy Hawkins. Worst: None. This was a good category. K-Rod, despite yielding Mariano Rivera's first RBI, has a ridiculous ERA+ of 348, giving up only 5 ER in 36.2 innings, with a .484 OPS against, 9.57 K/9 and accumulating 20 saves. Trevor Hoffman shows San Diego and the world he can still pitch with an ERA of 1.99, a WHIP of 0.971, and OPS against of .479 and 17 saves. And the best signing of all, LaTroy Hawkins, wasn't even supposed to be a closer but got forced into the duties and did a great job, racking up 10 saves with 2.62 ERA. 

What do you think? Anyone I left off this list or anyone you disagree with?
