SEATTLE -- The Red Sox recalled reliever Chris Carpenter, who is ranked ninth among the club's Top 20 prospects, and the hard-throwing right-hander immediately saw action, walking one and getting a groundout in one-third of an inning in the club's 4-1 loss to the Mariners on Monday afternoon.

Acquired from the Cubs as part of the compensation for former general manager Theo Epstein, Carpenter started the season on the 60-day disabled list while recovering from right elbow surgery. He has made 16 appearances with Triple-A Pawtucket, going 1-0 with four saves and a 1.15 ERA. Triple-A batters were hitting just .137 off the 26-year-old.

"Very good, especially when he's down in the zone," manager Bobby Valentine said. "He's got a couple pitches that are pretty hard to hit when they're down. Good fastball, good slider. One-inning guy."

Carpenter allowed three runs in 10 appearances last season, walking seven and striking out eight.

With first-inning double, Pedroia gets 1,000th hit

SEATTLE -- Dustin Pedroia hit a ground-rule double in the first inning of the Red Sox's 4-1 loss to the Mariners to record his 1,000th career hit.

The second baseman is the 31st player in Red Sox history to reach 1,000 hits, but just the second primary second baseman. Additionally, Pedroia is only the sixth player in franchise history to reach 1,000 hits in 833 games or less.

The only other Red Sox players to reach 1,000 hits quicker were Nomar Garciaparra (746), Wade Boggs (747), Johnny Pesky (774), Ted Williams (814) and Jim Rice (827).

The first-inning double also extended Pedroia's hitting streak to a season-high tying 14 games. Pedroia, who also singled and stole two bases on Monday is batting .386 (22-for-57) during the streak.
