Oakland A's outfielder Josh Reddick is out of the lineup Wednesday against the Baltimore Orioles because of back tightness, according to the team's official website. Reddick was scratched from the lineup Tuesday due to the issue, and while he would have likely sat anyway with left-hander Wei-Yin Chen on the mound for the Orioles, it is unclear if he will be able to return Thursday. Sam Fuld will get the start in right field and bat second in place of Reddick, who is hitting .283 with 13 home runs and 45 RBI in 98 games this season. “Every time my foot would hit the ground, it kind of would sting a little,” Reddick told the Sacramento Bee after suffering the injury Sunday against the Cleveland Indians when he run into the Indians' bullpen in the fifth inning while trying to make a catch.
