Alfredo Aceves refused to throw at full strength during a live batting practice session Sunday. Aceves is a valuable pitcher and capable of filling multiple roles for the Red Sox, but this isn't the first time he's clashed with management, and his unorthodox ways have become a concern. "The one thing I'll say about that is he didn't go through the drill as intended," manager John Farrell said. "We have addressed it." The relationship between Aceves and Farrell will be a situation to monitor in spring training. Full video of the throwing session is available in the attached link.
