As Dustin Pedroia continued his campaign last night to wrap up the Gold Glove at second base before the midway point of the season, he also timed his defensive highlights for just the right time. They saved the Red Sox from defeat. In the 10-8, 14-inning victory against the Rays, Pedroia made a pair of defensive plays that kept the Red Sox’ drive to survive this game alive. The second one was the best. The Rays had scored twice in the 10th inning against closer Andrew Bailey and had runners on first and third with two outs. Speedy Sam Fuld was up, and he pushed a bunt up the first base side. Pedroia had been playing back but he raced in and gobbled it up, making an off-balance throw to Mike Carp at first base. “That was an unbelievable play,’’ said Bailey. “In spring training we worked hard on that play; that was one that our coaching staff really hammered on us, and Pedey’s the best second baseman in the league. The way he goes after the game is remarkable and there’s only one of him. Obviously that’s a huge play by him and a game-saver.’’ Catcher Jarrod Saltalamacchia saw the play unfold before his eyes. Even before it happened, he had a hunch it could and he knew that the Red Sox had the right guy in place to defend it.
