LAKELAND, Fla. -- If there's one common thread to Bruce Rondon's four walks in 2 2/3 innings this spring, it's the high fastball. When he gets to throwing his fastball up, it appears tough for him to get it down.
Manager Jim Leyland isn't a pitching coach, but he has a mechanical explanation for this.
"Normally, that means you're getting out front a bit too much and your arm's not catching up," Leyland said. "You're usually dropping your elbow a little it. That's usually, mechanically, what happens."
He also has a more general explanation -- not simply for Rondon but for most hard throwers.
"I've never seen any pitcher in my life that throws 100 mph and has good control with it," Leyland said. "I don't give a care what anybody says. When they throw it 100, they're throwing it 100. When they're throwing it 100, they're winging it."
