Hitting hasn't exactly been a science for Brandon Moss, whose bat has become one of the Oakland Athletics' most dangerous weapons since he returned to the American League last season. Moss tied a career high with five RBIs, including his second homer in two games, and the A's extended their winning streak to seven games with an 11-5 victory over the Los Angeles Angels on Wednesday night. The seven-year veteran first baseman's other five-RBI game was on Sept. 29 against Seattle, when he hit a game-ending, three-run homer in the 10th inning to give Oakland a 7-4 victory. It came during a season-ending six-game winning streak that propelled the A's to their first AL West title since 2006.
