Brett Anderson matched his career high with 10 strikeouts in six innings as the A's completed a sweep of the Houston Astros with a 9-3 win Sunday, but the club's fifth consecutive victory didn't come without cost. Right fielder Josh Reddick, who led the team in homers and RBIs last year and who also won a Gold Glove for his defense, had to leave the game in the fifth inning with a right hand or arm injury after sliding into the right field wall at Minute Maid Park. Reddick was in hot pursuit of a foul ball off the bat of the Astros' Jose Altuve when he dove for the ball at the bend in the right field wall in foul territory. Reddick's momentum was such that he continued to slide on the warning track until he smashed into the wall as the ball bounced free. Trainer Nick Paparesta and manager Bob Melvin were two of the first to the scene. Reddick stayed on the ground for a minute or two, then got up and walked off the field, holding his arm. There was no immediate word about the severity of the injury. It was a busy day for Paparesta and the medical crew. The left-handed Anderson twice needed attention after having grounders up the middle glance off his pitching hand. He remained in the game both times and didn't come out until after a long sixth inning when Houston scored two unearned runs off him. By that time the A's had built up a commanding lead, scoring twice in the second and third, once in the fourth and three times in the fifth. Included in the offensive onslaught were homers by Jed Lowrie, Coco Crisp and Chris Young.
