Cleveland Guardians pitcher Luis Ortiz was placed on non-disciplinary leave on Thursday due to a gambling investigation by Major League Baseball, 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.

ESPN reported the firm IC360 recently also sent an alert to sportsbook operators regarding Ortiz.

The Athletic was the first to report that Ortiz’s suspension was related to gambling.

MLB said Ortiz’s paid leave is through the end of the All-Star break, when players return to their teams July 17 and games resume the following day. It can be extended if the investigation remains ongoing.

MLB and the Guardians had no further comment on the investigation. Ortiz returned to Cleveland on Wednesday night.

The 26-year old Ortiz is in his first season with Cleveland after he was acquired in a trade with Pittsburgh last December. The right-hander is 4-9 with a 4.36 ERA and 96 strikeouts in 16 starts this season.
