The most difficult task for young pitchers is to have command of the strike zone, and failure to do so keeps so many in the minor leagues.
Lehigh Valley righthander Phillippe Aumont is a classic example. The Phillies rave about his stuff, but his inability to throw strikes consistently caused his demotion to the IronPigs.
He averaged 6.9 walks per nine innings this season when the Phillies sent him down.
"He is like a lot of others in that they are a work in progress," Lehigh Valley manager Dave Brundage said. "It is about gaining confidence, and we're in the stage that he and a lot of young pitchers need something positive going on, and we will dwell on the positives . . . ."
