This offseason was a crazy one, and there were a lot of players that parted ways with the organization. Some retired (Ellis Burks, Curtis Leskanic), some were traded (Dave Roberts), and some flat out left (Pedro Martinez). I'm going to catch you up on them if you haven't been paying attention already.
As the stats show, Pedro Martinez has been the only successful pitcher this season out of those who left the Red Sox. Martinez is making a case for a National League Cy Young award with his 2.60 ERA and 11-3 record. He has practically carried the Mets on his shoulders this season, as the next most effective pitcher has been Victor Zambrano who is 4-8 with a 3.51 ERA. I can almost guarantee, though, that if the Red Sox were able to resign Martinez, he wouldn't be pitching as well as he is now. The change of scenery did a favor for him, and he thrives when there are people supporting him all the time. I think he felt that the Fenway Faithful wasn't supporting him as much as years past, so he had to get out. Now he's dominating the National League.
Derek Lowe started the season well with a 2.04 ERA in April, but since then he has fallen off the map. He currently has a 9.22 ERA in July, and it doesn't look like it will get any better for former closer of the Sox.
Both Byung-Hyun Kim and Pedro Astacio have had rough seasons, and we kind of had to expect that. Kim has been horrible as a Red Sox, so it shouldn't get better as he has been pitching in the best hitter's park in the world. Astacio falls in the same mold as Kim, as he hasn't pitched well in Texas, and more recently in San Diego where he was traded a short while ago. Terry Adams has a small sample size, but he's been bad in his number of innings for the Phillies this year.
Some other pitchers from last year's squad haven't made a big league appearance this year because they've either been hurt or in the minor leagues. Scott Williamson and Ramiro Mendoza are a few that come to mind. Williamson won't be ready until next year at the earliest, while Mendoza has thrown off the mound recently for the New York Yankees.
Dave Roberts, or the base-stealer formerly known as Roberts, has been the best out of this bunch this season. Roberts' base stealing production is down, but he's hitting the ball decently well, and has a decent VORP (Value Over Replacement Player. Thank you, Marc) at 13.3. He has also hit a career high already in home runs, with 6, as his former high was four last season with the Dodgers and the Sox.
Doug Mientkiewicz has shown power for the Mets this season, but he can't hit the ball consistently. He has also spent a good deal of time on the disabled list, as he was just activated on the 16th, designating, ironically, Brian Daubach for assignment (Don't get any ideas, Theo). Mientkiewicz is walking, though, like he usually does, as his on-base percentage is .312. It's not a good OBP, but when you are batting only .224 it looks a lot better.
Orlando Cabrera has been decent for the Angels this season. People are complaining about Edgar Renteria having a poor season, but we could still have Cabrera who is hitting in the .250's and has a VORP of 7.7. Compare that to Renteria who is hitting in the .270's with a VORP of 14.6. Any more complaints?
A few guys from last season that haven't made a big difference are Sandy Martinez, Pokey Reese, and Ricky Gutierrez. Martinez and Gutierrez have been in the minor leagues, while Reese has been injured for the season.
