Boston Red Sox first baseman Triston Casas suffered a ruptured tendon in his left knee and is out for the remainder of the season, the team said.
The 25-year-old Casas ruptured his patellar tendon running to first on a slow roller up the line and fell awkwardly in Boston\'s victory over the Minnesota Twins on Friday night. After laying on his back in pain -- not moving the knee -- he was carted off on a stretcher before being taken to a Boston hospital.
