Grossman reported the initial soreness after sliding into a base, though it's unknown if that was when the injury actually occurred. Grossman last appeared in an AFL game on Nov. 8. The switch-hitting outfielder was hitting .375 with five doubles, seven homers, 22 RBIs, six stolen bases and a .472 on-base percentage in 26 AFL games before his fall league stint ended.
The Pirates will get a better feel for Grossman's recovery timeline after the surgery. However, the club does not anticipate the injury keeping Grossman from being ready for the start of Spring Training. The typical recovery time for this type of surgery is one-to-two months. The longer-term concern is Grossman's power. It often takes players at least a year after surgery to regain full power in their swing.
Fellow Pirates outfield prospect Starling Marte and Pirates third baseman Pedro Alvarez are among those in the organization who have had hamate surgery in the past.
