Indians right fielder Shin-Soo Choo was placed on the 15-day disabled list Thursday morning because of a left oblique strain. The Indians recalled right-hander Corey Kluber and lefty Nick Hagadone from Class AAA Columbus. Choo's DL stint is retroactive to Aug. 28. Choo was placed on the DL in order to allow Hagadone back on the roster. Hagadone was with the Indians from Aug. 26-28 but did not appear and was optioned to Columbus. Without an injury to another player, the Indians would have been required to wait 10 days to recall Hagadone. The Indians need pitching help after a 16-inning victory over Oakland on Wednesday night. The game ended just past midnight. Frank Herrmann, who pitched the final four innings for the Tribe, is unavailable.
