Emmanuel Clase, the dominant closer in the American League for the last four years, was placed on non-disciplinary leave Monday. He joined Luis Ortiz, a member of the starting rotation, who was placed on leave July 3.

CLEVELAND — Major League Baseball and the player’s association have agreed to extend Cleveland Guardians pitcher Luis Ortiz’s paid administrative leave through Aug. 31 “while MLB continues its investigation,” the league announced Friday.

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