It’s popular — if not almost obligatory — to criticize Craig Breslow and the job he’s done as chief baseball officer of the Red Sox. The numbers tell the story: a record which is 11 games under .500 and a position in the basement of the American League East. Unless the Red Sox execute a second-half turnaround, this season will mark the second time in three years that the Red Sox, under Breslow, have failed to win more games than they lose.
