During Sunday’s game the Red Sox announced that first baseman Triston Casas has undergone successful patellar tendon repair surgery on his left knee.

The procedure was performed by Dr. Eric Berkson at Massachusetts General Hospital.

Casas suffered the injury while running the bases in Friday’s 6-1 win over the Twins, rupturing his tendon while trying to beat out a throw at first base in the bottom of the second inning. Casas remained on the ground for several minutes after the injury and was eventually carted off the field in a stretcher and taken to the hospital.

The first baseman is expected to miss the remainder of the season.

Prior to the injury Casas had endured a difficult start to the year but was showing signs of improvement. The 25-year-old batted .182 with three home runs and 11 RBI on the season but had posted a .261 average with two homers, seven RBI and a .936 OPS over his last eight games.

Casas has also endured numerous other injury setbacks in his career, including a torn cartilage in his ribcage last season that kept him out for nearly four months.

With Casas out the Red Sox plan to use Romy Gonzalez as their starting first baseman for now, and the club also called up Abraham Toro from Triple-A to serve as additional depth at the position. The club has for now ruled out using Rafael Devers at first base, with manager Alex Cora insisting he will remain at designated hitter.
