ST. LOUIS (BaseballStL) -- Shelby Miller, the Cardinals top prospect, is finding out the hard way that there is a difference between Double-A and Triple-A.
Miller has fallen victim to his own fastball while posting a 4-4 record with a 5.18 ERA in 12 starts with the Memphis Redbirds this season.
"My fastball doesn't really get swung and missed at as much as it was in the lower levels," Miller told MILB.com's Chris Jackson. "It's more fouled off. I can throw four of them in a row and it gets fouled off. Eventually the pitch count is going to rise up and I'm going to throw five innings instead of six or seven."
Before Monday's start, Miller has pitched only six innings in two of his last ten starts. It has been a far cry from last year's success when Miller posted a 11-6 record with a 2.77 ERA in 25 starts with Double-A Springfield and Class A Advanced Palm Beach.
