NEW YORK (AP) Texas Rangers catcher Melvin Novoa has been suspended for 56 games under baseball's minor league drug program following a positive test for the banned performance-enhancing substance Clostebol.

In addition, Boston Red Sox catcher Jhon Nunez has been suspended 25 games, the commissioner's office said Monday. A 25-game suspension is the penalty for a first violation for use or possession of a syringe at a team facility, in team-provided housing or while traveling with a club.

Novoa, 19, is to start serving his penalty when the Arizona League season begins.

There have been 57 suspensions this year under the minor league drug program.
