The Boston Red Sox recently had to make a change in the infield. Boston lost first baseman Triston Casas to a serious knee injury and it seems likely at this moment that he's not going to be back this year.

Casas suffered the injury while running to first after hitting a slow roller up the first-base line in the second inning of Boston's 6-1 win over the Minnesota Twins on Friday. He fell awkwardly and was carted off the field before he was eventually hospitalized.

Boston Red Sox first baseman Triston Casas suffered a ruptured tendon in his left knee and is out for the remainder of the season.
