Tigers placed RHP Doug Fister on the 15-day disabled list with a left costochondral strain. The injury occurred in the fourth inning of Fister's Saturday debut against the Red Sox. Drew Smyly should slide into Fister's slot in the Detroit rotation, with Duane Below, Andy Oliver and Jacob Turner the leading candidates to take over the No. 5 spot. It's not clear how long the 28-year-old right-hander is going to be out.
