Hernandez, 25-36 for career in majors, will miss 50 games at start of '09 season

NEW YORK -- Houston Astros minor leaguer Runelvys Hernandez was suspended 50 games Saturday after testing positive for an amphetamine.

The pitcher's penalty will take effect at the start of next season, the commissioner's office said. Hernandez most recently was with Triple-A Round Rock of the Pacific Coast League.

Hernandez made four starts for the Astros this season, going 0-3 with an 8.38 ERA. He also pitched for the Kansas City Royals from 2002-03 and 2005-06. The right-hander has a major league record of 25-36 with a 5.50 ERA in 82 career games, all starts.

A total of 54 minor leaguers have received bans since July 25, including 39 from the Dominican Summer League and 10 from the Venezuelan Summer League.
