Triston Casas wasn't hitting well at all, but he still may have been the one player the Boston Red Sox weren't prepared to lose. The Red Sox truly didn't have other first basemen on the roster behind Casas.

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 on Saturday.

But the Red Sox have the depth within their system to find a legitimate outside answer. And remember: the team managed to play .500 ball last year without having a full-time run-producer at first. With an improved rotation, a better bullpen and the addition of Alex Bregman, they should be able to survive.
