Agent Cooper

http://web.minorleaguebaseball.com/milb/st...wtdaax_biraax_1 What's the story with clayton richard? His groundball rate was stellar(14:3), and his K/BB has been impressive all season. The only time I've seen him was in a spring training game 2 seasons ago, and I haven't heard anything about him as a prospect. Is there a reason for his improved control and increased K rate this season?
