"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."

Domínguez began the day in his second season with the Baltimore Orioles, who acquired him at the trade deadline last season. One trade later, he was a member of the Toronto Blue Jays, pitching a scoreless inning against their opponent, the Baltimore Orioles.

Three-time All-Star Emmanuel Clase has been placed on "non-disciplinary paid leave" as MLB looks into illegal gambling activity.
