Stephen Drew has struggled to find his swing after a concussion caused him to start the season on the disabled list. Bumped down the Red Sox batting order in the No. 9 spot because of a batting average below .200, the shortstop seemed to rediscover his groove in last night’s 11-inning, 6-5 victory over Minnesota at Fenway Park. He provided a Wall-scraping walkoff double with two out in the bottom of the 11th, scoring Jarrod Saltalamacchia from second base. For the game, Drew went 4-for-5 with a season-high three RBI. Drew had an RBI single in the fifth, then a solo home run in the seventh to tie the game at 4-4. He has 12 RBI on the season with 11 in the last 10 games. Drew’s game-winning hit was the third walkoff hit of his career. “I was more or less just trying to get in rhythm and I’ve been working on things,” said Drew. “Tonight was a good night for me and I hit it good, but you never know here. “It was a good night,” he continued, “and everybody battled and nobody gives up here. This (team) is winning games and having fun.” The Red Sox final rally had an inauspicious beginning with two outs and the slowest guy in the lineup at the plate. Saltalamacchia beat out an infield hit and went to second on a Will Middlebrooks single to left-center. It took more than a routine single to bring home the slow-footed Saltalamacchia from second. “That’s probably the last infield hit I’d get and I was hoping Stephen would hit the ball off the Wall or something, so I wouldn’t have to run too fast,” said Saltalamacchia.
