The Miami Marlins placed pitcher Jose Fernandez on the disabled list Sunday because of a biceps strain, according to MLB.com. Fernandez had performed well since returning from Tommy John surgery in late July, tallying a 2.30 earned-run average and 53 strikeouts in 43 innings, but he will return to the DL after leaving his last start against the Atlanta Braves having thrown just 76 pitches. "I spoke to Jose this morning. I think he definitely has peace of mind as to what now. Hopefully the inflammation will go out of there and we can get him healthy, get him back," manager Dan Jennings said Sunday, adding that there is no timetable for a return. "I think it can vary. It will just be when that calms down. Now that we know and have it identified, I think we'll have a better understanding of exactly how aggressive to treat it."
