BOSTON -- Jamey Carroll stroked his fourth hit of the game to deliver Darin Mastroianni from second base with one out in the 10th inning, capping a comeback that saw the lowly Minnesota Twins rally from a 5-1 deficit and nip the Red Sox 6-5 Friday night.
Mastroianni led off the inning with a double off loser Vicente Padilla (4-1). Brian Dozier attempted to sacrifice but his foul pop was caught by diving third baseman Will Middlebrooks. Carroll, who also had a walk in the game, then came through to give Jeff Gray (6-1) the win.
Jared Burton worked the bottom of the inning (perfect but two loud outs) for his fourth save and the Twins, losers of 10 of their previous 11 games at Fenway Park, won their second straight to start this four-game series.
The Red Sox, who lost their third straight to again fall below .500 (53-54), wasted a major scoring chance in the eighth inning. They loaded the bases with one out, only to have lefty Tyler Robertson strike out Jacoby Ellsbury and Gray to get Dustin Pedroia to fly to right. They also had the winning run on second with two out in the ninth and Gray got out of that as well.
Justin Morneau, who dropped a foul pop fly that continued a Carl Crawford at-bat that turned into a three-run homer in a four-run Boston third, had four hits (and was hit by a pitch in the ninth inning) in the win.
The four hits tied Carroll's career high.
Twins starter Brian Duensing worked the first six innings, while his counterpart, Felix Doubront, went the first five, yielding four runs that tied the game in the fifth.
The Red Sox fell to 2-6 in extra-inning games.
After both teams wasted two hits in the first inning, both scored a run in the second.
Morneau, hitting .133 against lefties through July 19 but 9-for-20 against them since coming in, opened with a double, the third hit in five Minnesota hitters against Doubront with a fourth retired on a fine running catch by Ellsbury. Morneau took third on a long fly to right and scored when Mastroianni had a broken bat single through the drawn-in infield, Boston manager Bobby Valentine deciding to bring the infield in in the second inning of a scoreless game.
With two out and nobody on in the bottom of the inning, Crawford doubled and scored on Kelly Shoppach's single.
The Sox went ahead in the third inning with four runs, the last three runs scoring after Morneau's miscue.
Successive singles by Pedroia (his second hit), Cody Ross and Adrian Gonzalez (he hit into a double play to end the first) broke the tie. After two outs, Morneau dropped the pop and Crawford hit his second homer in the last three nights on the next pitch.
The Twins then rallied to tie with the help of some Doubront wildness in a four-run fifth. A pair of singles and a pair of walks brought one run in before Morneau lofted a two-run single into right-center. Ross then made a fine running catch of a Valencia drive into the right field corner, the sacrifice fly tying the game.
Two more Minnesota errors created a problem in the bottom of the inning, but Boston couldn't score.
