Joel Hanrahan felt renewed soreness in his right hamstring when he threw on flat ground Thursday. The Red Sox had hoped he could throw from a mound soon, but that now won't happen for at least a few days. "While he's making progress, that hasn't cleared up 100 percent," manager John Farrell said of Hanrahan's hamstring. While Hanrahan suffered what appears to be a mini-setback Thursday, Andrew Bailey was nailing down his second save in as many days in impressive fashion. If Bailey gets hot, it's possible Hanrahan won't have a closer job once healthy.
