Cleveland Guardians pitcher Luis Ortiz is the subject of a Major League Baseball gambling investigation and was placed on non-disciplinary leave Thursday, two people with knowledge of the investigation told The Associated Press. The people spoke to the AP on condition of anonymity due to the nature of the investigation. The investigation is related to in-game prop bets on two pitches thrown by Ortiz that received higher activity than usual during his starts at Seattle on June 15 and his recent outing against St. Louis on June 27. The gambling activity on the pitches was flagged by a betting-integrity firm and forwarded to MLB.
