Gary Tuck, the Red Sox' bullpen coach and catching instructor since 2006, has chosen to retire, reports CSNNE's Jessica Moran.
Tuck served with new manager John Farrell on Terry Francona's coaching staff from 2007-10, and had been recruited by Farrell to join him in Toronto when Farrell was named Blue Jays manager in 2011. He had agreed to remain with the Sox after Farrell's hiring in October, which made the timing of his resignation -- exactly two weeks before pitchers and catchers report to Fort Myers -- curious.
Tuck would have been the only member of Bobby Valentine's 2012 coaching staff to come back this season.
WEEI's Rob Bradford was first to report Tuck's departure from the team.
Evan Drellich explains why he is not ready to be concerned about Rick Porcello following a loss to the Twins.
BOSTON - Adalberto Mejia pitched 5 2/3 innings in his second straight scoreless start, Max Kepler hit a two-run homer and the Minnesota Twins rebounded from two consecutive losses against Boston to beat the Red Sox 4-1 on Wednesday night.
Kepler also had an RBI single, and Miguel Sano added an RBI double to help the Twins improve to 24-11 on the road.
Mejia (3-3) allowed five hits, struck out three and walked one. On Friday night at Cleveland, the rookie left-hander held the Indians to two hits over five innings in a victory.
Brandon Kintzler got the final three outs for his 21st save.
Boston starter Rick Porcello (4-10) gave up four runs on six hits in six innings, striking out six and walking two. It was his 14th straight start going at least six innings, the AL's longest active streak.
Red Sox manager John Farrell was back in the dugout after serving a one-game suspension Tuesday for poking umpire Bill Miller in the chest during an argument Saturday.
