BOSTON -- Felix Doubront still hasn't yet figured out why a fastball that averaged close to 94 miles per hour last season barely got to 92 on Friday against the Texas Rangers. But he's confident his velocity is going to come back. "I'm doing my best to get it," he said. "I don't have my 95 and 96, but one day it's going to explode, and I'm going to be the same as last year. I don't worry about that. There's nothing wrong with my arm."
