Who will be the Boston Red Sox's solution at first base? Triston Casas suffered a very likely season-ending knee injury and now the team has a serious question in front of them. The short-term fix Romy González but will they make an addition?

The one thing the Red Sox know about their situation at first base is that Triston Casas won’t play for the rest of the season. Casas ruptured his left patellar tendon on Friday and underwent successful surgery on Sunday that will require an extensive rehab.

Casas was removed in the bottom of the second inning after suffering what manager Alex Cora described as a “significant (left) knee injury.”
