The Cardinals have released right-handed pitchers Mark Diapoules and Houston Summers from minor league camp, according to Derrick Goold of The St. Louis Post-Dispatch. Summers signed with the team as a minor league free agent last year while Diapoules was St. Louis' 21st round pick back in 2006.
Diapoules, 22, spent most of 2010 with High-A Palm Beach, where he posted a 2.44 ERA with 6.2 K/9 and 4.1 BB/9 in nine starts and five relief appearances. He also made two starts for Double-A Springfield but did not fare well, pitching just 5.1 innings combined.
According to Goold, there was no room for Diapoules as the organization's higher-level bullpens are more or less set. By releasing him now, the club is giving him the opportunity to hook on elsewhere before rosters are cemented in a couple of weeks.
