Cleveland Guardians pitchers Emmanuel Clase and Luis Ortiz had their paid leaves extended indefinitely as Major League Baseball continues an investigation to gauge their possible involvement in gambling during games. Clase and Ortiz were initially set to sidelined until at least Aug. 31. MLB and the players’ union said in a news release they have agreed to extend the nondisciplinary paid leave “until further notice.” It’s possible the pitchers will be out at least until the end of the regular season, which concludes Sept. 28. The Guardians recently cleared out their lockers, a sign they were unlikely to return in the final month.
