The investigation is related to in-game prop bets on two pitches thrown by Ortiz that received higher activity than usual during his starts.

CHICAGO — Guardians pitcher Luis Ortiz has been placed on “non-disciplinary paid leave” through the end of the All-Star break as a result of an MLB investigation, with multiple sources telling The Athletic that the probe is related to gambling.

"The Guardians have been notified by Major League Baseball that Luis Ortiz has been placed on leave per an agreement with the Players Association due to an ongoing league investigation," the statement said. "The Guardians are not permitted to comment further at this time and will respect the league's confidential investigative process."
