The Boston Red Sox have a long list of needs to address this offseason, including holes in the rotation and a power outage in the lineup. They could also need an Opening Day first baseman.
Red Sox first baseman Triston Casas ruptured a patellar tendon while running the bases in May and quickly underwent surgery to repair the devastating knee injury. He missed the rest of the season with Boston, and he may not be ready to play by Opening Day, although there is some cautious optimism that he could be.
Even if he is ready, the Red Sox should have a backup plan in place for Casas.
