BOSTON -- C.J. Wilson and four relievers combined on a nine-hitter and the Los Angeles Angels took over sole possession of first place for the first time since opening day, 2013, with a 4-2 victory over the Boston Red Sox on Monday night.

Technically, the Angels, who have won seven of their last nine games at Fenway Park, led the idle Oakland Athletics by a percentage point coming into the game. But they now have a half-game lead, their first actual games lead since winning last year's opener.

The Angels visit Oakland this weekend and then host the A's next weekend.

Center fielder Mike Trout and designated hitter Albert Pujols stroked back-to-back RBI hits off hard-luck loser Brandon Workman in the third inning and Red Sox reliever Junichi Tazawa was guilty of a double error with the bases loaded in the eighth, good for two more runs.
