ST. LOUIS -- An unnamed scout weighed in on Trevor Hoffman's recent troubles in a column by ESPN.com's Jayson Stark, saying the problem was arm speed.
"To be honest, I think his body is quitting on him," the scout said. "He doesn't have the arm speed to make his [changeup] effective anymore. That was always the one thing he had. Even after he lost his fastball, he still had the arm speed. And now it's gone."
Brewers manager Ken Macha was asked whether that's a valid criticism.
"I think arm speed has something to do with things, but I'm not necessarily saying that's what it is [with Hoffman]," Macha said. "You have to have good arm speed with your changeup, and I don't see a discernible difference in his arm speed between his fastball and his changeup."
