Reddick slipped while fielding a fly ball hit by Paul Konerko for the second out of the second inning, Melvin said. He struck out in his only at bat of the game midway through the first.
Melvin has been cycling his five outfielders this spring and said before the game that each would get 400-500 at-bats this season. The starters are Yoenis Cespedes in left, Coco Crisp in center and Reddick in right, where he won a Gold Glove last season, his first for the A's after playing three seasons in Boston.
Newcomer Chris Young and holdover Seth Smith are the other outfielders. Young was in left with Cespedes at designated hitter on Friday night.
Reddick played in 156 games and batted .242 with 32 homers and 85 RBIs in 2012 as the A's won the American League West title and lost to the Tigers in a five-game AL Division Series. This spring, he's batting .306 (11-for-36) with three homers and 10 RBIs.
