Erik Bedard dealt to Red Sox

SEATTLE -- The Boston Red Sox have added a much-needed starter after an earlier trade fell through, acquiring oft-injured left-hander Erik Bedard from the Seattle Mariners in a three-team deal at the deadline Sunday.

The Red Sox, whose deal for Oakland's Rich Harden fell apart late Saturday night, also got right-hander Josh Fields, a 2008 first-round draft pick.

"He was real tough on us," Boston manager Terry Francona said of Bedard, who started his major league career with the Baltimore Orioles.

"He's a guy who has shown he can pitch in the American League East. First half of the year before he tweaked that knee he was pretty solid," Francona said. "His stuff was good. We're excited."

Francona said he would talk to Bedard before lining up his rotation for the coming week.

"I know that (general manager) Theo (Epstein) talked to him and he sounded like he was excited. We'll kind of build him back up," Francona said. "He just came off the DL Friday. We'll build him back up and get him in there."

Boston sent catcher Tim Federowicz and right-handers Juan Rodriguez and Stephen Fife to the Los Angeles Dodgers, who dealt OF Trayvon Robinson to the Red Sox.

The Red Sox then sent Robinson and OF Chih-Hsien Chiang to Seattle.

Bedard, who is 4-7 in 16 starts with a 3.45 ERA this season for the Mariners, wasn't so good against an AL East team on Friday when he faced Tampa.

He showed the effects of his 32-day layoff after going on DL with a sprained left knee. He threw 57 pitches in just 1 1/3 innings and was tagged for five runs and three hits, walking four and striking out two.

AL East-leading Boston was in need of a starter to help shore up its rotation with Daisuke Matsuzaka out for the season and Clay Buchholz on the disabled list.

"Clearly, we have some concern for Clay," Epstein said Sunday night about Buchholz, who has been on the disabled list since June 17 with a lower back strain. "It's been a couple of months now, which is longer than we expected it to be. We're still awaiting some more feedback and another opinion. I think we have a feel for what might be going on, but Clay is seeing another expert (Robert Watkins) to get his opinion and then we're all going to put our heads together this week.

"I'll refrain from answering in too much detail until we have a chance to talk to Clay and we have a chance to talk things through ... we think we're in the process of getting to the bottom of it, and we're all going to put our heads together early this week and talk about it with Clay before we discuss it publicly."

Mariners general manager Jack Zduriencik said of the trade: "We talked with a few other clubs but in the end we thought this was the one that made sense."

Dodgers GM Ned Colletti said he'd been talking to Boston about "a number of different things."

"They had a little bit of a surplus of catching, and Federowicz is somebody we have watched a lot in Double-A," Colletti said. "He is a very good defensive player and a good leader. Offensively, he is still a work in progress. We started with him."

The Mariners sent Baltimore five players for Bedard before the 2008 season but he has been a bust because of injuries.

Bedard was 15-14 with a 3.31 ERA in 46 appearances with the Mariners. He missed most of the 2009 season and all of 2010 after left shoulder surgery. He was 4-7 with a 3.65 ERA in 16 starts this season but spent most of July on the disabled list (knee).

He was 40-34 in five seasons with the Orioles, going 15-11 with a 3.76 ERA in 2006 and 13-5 with a 3.16 ERA the following season.

Fields, 25, the 20th player taken in the 2008 draft out of Georgia, was 2-1 with a 2.77 ERA for Double-A Jackson and 0-0 with a 6.23 ERA in nine games for Triple-A Tacoma.

"We've been talking Chiang for a while. Robinson came in a couple hours (before the deadline) as we discussed it," Zduriencik said. "He was the guy we settled on."

The Mariners have been struggling offensively -- they designated Jack Cust for assignment Friday -- and both 23-year-old prospects have power potential.

Robinson is hitting .293 with 26 home runs and 71 RBIs for Triple-A Albuquerque.

"He'll go to Tacoma and we'll watch him there," said Zduriencik, when asked if Robinson was close to a promotion. "We'll see what happens."

Chiang is hitting .338 with 36 doubles, 18 home runs and 76 RBIs in 87 games for Double-A Portland.
