OAKLAND, Calif. (AP) — Coco Crisp singled in Alberto Callaspo with one out in the 10th inning and the Oakland Athletics beat the Boston Red Sox 2-1 on Saturday to extend their winning streak to five games.
Callaspo drew a leadoff walk against reliever Edward Mujica (2-3) and was sacrificed to second. Red Sox closer Koji Uehara replaced Mujica before Crisp lined his first pitch into right field. Boston right fielder Brock Holt made a strong throw but Callaspo slid home with the game-winner.
It's the second game-ending hit for Crisp this season and seventh of his career.
The A's have won the first three games of this four-game series by a total of four runs.
Boston was shut out for the first seven innings before Dustin Pedroia scored on a wild pitch in the eighth.
The Red Sox missed a chance to take the lead in the top of the 10th when Oakland reliever Dan Otero struck out David Ortiz with two on and two out.
A's manager Bob Melvin was ejected after arguing a controversial call in the eighth, moments before Pedroia scored the game-tying run.
Boston put runners on the corners with two outs when Oakland reliever Luke Gregerson appeared to strike out Mike Napoli. Napoli argued that he fouled the ball off the dirt, and home plate umpire Quinn Wolcott agreed although television replays appeared to indicate otherwise.
Under the current replay system, balls and strikes are not reviewable..
Gregerson, who had celebrated the apparent strikeout, bounced his next pitch in front of home plate. The ball ricocheted off the chest protector of catcher Stephen Vogt and rolled toward the mound as Dustin Pedroia scored from third.
After Napoli flew out to end the inning, Melvin raced out from Oakland's dugout and angrily confronted Wolcott before getting tossed.
The play prevented Oakland starter Jesse Chavez from winning his second straight start. Chavez took a no-hitter into the sixth and held the Red Sox scoreless through seven before giving way to the bullpen. He struck out four and walked four.
Boston starter Rubby De La Rosa nearly matched Chavez in his first career appearance against the A's.
De La Rosa, who struck out four and walked four, retired the first six batters before Vogt's triple off the extended wall in right-center.
Vogt scored on Alberto Callaspo's sacrifice fly despite a stellar play by Holt, who had made a diving catch on Callaspo's sinking liner in the gap in right-center then threw home.
Oakland managed only six runners over the next six innings until Callaspo's leadoff walk in the 10th.
