"Per an agreement with the MLBPA, Cleveland Guardians pitcher Emmanuel Clase has been placed on non-disciplinary paid leave through games on August 31st while MLB continues its sports betting investigation," MLB said in a statement. "We will not comment further until the investigation has been completed."

The development delivers a crushing blow to a Guardians team that was hanging around the periphery of the Wild Card race.

MLB's Department of Investigations is handling the investigation of Guardians pitchers Luis Ortiz and Emmanuel Clase.
