Red Sox designated hitter David Ortiz appears headed back to the disabled list only days after being activated, and the Boston slugger could be shut down for the remainder of the season due to a lingering right Achilles strain. Prior to Sunday's 8-6 victory over the Kansas City Royals, Ortiz said he expected a decision on whether he would go on the DL and call it a season to be made by the end of the game, but he did not have a definitive update, saying the situation likely will be finalized Monday. "Right now all I'm trying to do is focus on getting better and make sure I'm ready to go next season," Ortiz said after the game.
