Adam Liberatore, who had a 0.85 WHIP and 0.61 ERA before the All-Star Break but 1.95 WHIP and 9.45 ERA after, is expected to undergo an arthroscopic left elbow debridement Tuesday, which should allow him to return for the 2017 season.
Dr. Neal ElAttrache will perform the operation in Los Angeles on Liberatore, who set a franchise record July 9 with his 24th consecutive scoreless appearance. Alex Wood recently returned to action after a similar procedure in July.
Liberatore was placed on the disabled list August 3 (retroactive to July 30), and pitched 9 1/3 innings in 14 games thereafter with a 9.64 ERA and 18 baserunners.
