"There's still a good pitcher in there once he gets back on track. Based on what we saw, it needs to be built back gradually," said Boston manager John Farrell to Danny Knobler of CBSSports.com.
Bard, 28, has struggled badly with his command since attempting to convert to a starting role in 2012. This season, he's pitched only one inning at the major-league level and has struggled badly in the minors across 16 appearances while missing significant time with an abdominal strain. However, from 2009-11 he pitched to a 2.88 ERA (154 ERA+) as the Red Sox's primary right-handed setup man.
Worth noting is that Bard was chosen by the Red Sox in the first round of the 2006 draft on the watch of then-GM Theo Epstein, who is of course now the Cubs' president of baseball operations.
