OAKLAND -- The Red Sox caught a break on a blown call by an umpire and thanks to some daring baserunning by Dustin Pedroia, took full advantage, tying their game with the Oakland A's in the eighth inning.
But as it turned out, that bit of good fortune only postponed the inevitable. For the second game in a row, former Red Sox outfielder Coco Crisp decided the game, lining Koji Uehara's first pitch to right, scoring Alberto Callaspo from second base to hand the A's a 2-1 victory.
The loss was the third straight for the Sox following three straight wins. Boston has scored six runs in the three games here to date.
Edward Mujica was handed the loss when he walked Callaspo to start the inning. A sacrifice by Nick Punto moved Callaspo to second, as Uehara, on the one-year anniversary of being named Red Sox closer, came in.
The Red Sox appeared to have been given a gift in the eighth when home plate umpire Quinn Wolcott ruled that Oakland catcher John Jaso didn't catch a foul tip by Mike Napoli on what would have been strike three and an inning-ending out.
Wolcott and the rest of the umpires gathered to discuss the call -- which wasn't eligible for a replay challenge -- and it stood. On the next pitch, Luke Gregerson bounced a pitch that Jaso kept in front him, just 10 feet in front of the plate.
But Dustin Pedroia, at third base, seized the opportunity and made a mad dash for the plate and eluded Jaso's tag to score the tying run.
Over the first seven innings, Rubby De La Rosa did all he could to pitch the Sox to a win. As so many starters have found in recent weeks, however, being very good isn't good enough.
De La Rosa allowed a single run on four hits over seven innings, but with his teammates held scoreless until the top of the eighth, the best he could get was a no-decision.
He allowed just one walk and struck out seven while dropping his ERA in five starts to 2.51.
The lone run off De La Rosa, 2-3, came in the third when Stephen Vogt smacked a triple high off the wall in right-center and scored on a sacrifice fly by Alberto Callaspo.
AT A GLANCE
STAR OF THE GAME: Jesse Chavez
Chavez limited the Red Sox to just three hits over seven scoreless innings and likely would have been the winning pitcher had not home plate umpire Quinn Wolcott blown a call that led to the Red Sox' only run in the eighth.
HONORABLE MENTION: Coco Crisp
For the second game in a row, Crisp delivered the game-winning hit in the A's final at-bat. On Friday night, it was in the eighth inning; Saturday, it came in the 10th, as Crisp singled to right, scoring Alberto Callaspo.
GOAT OF THE GAME: Mike Napoli
The Red Sox cleanup hitter was 0-for-3, stranding three baserunners in his three hitless plate appearances and ending three innings.
TURNING POINT: In the top of the 10th, the Sox had a chance to break the 1-1 tie when Jackie Bradley Jr. and Brock Holt singled with one out. But the threat ended there as Dustin Pedroia flied out and David Ortiz struck out.
BY THE NUMBERS: After sweeping the Twins in three games by scoring just three runs, the Red Sox have now lost three straight to the A's by scoring six runs.
QUOTE OF NOTE: "I look at it like this: we are very close to becoming a team that will go on a run for an extended period. We've got a number of very strong things in place -- pitching, in terms of our rotation, our bullpen. I think we're playing very good defense. But we've let situations get away from us as far as men in scoring position.'' -- John Farrell.
