Jesus Montero batted just .208 with three home runs and a .590 OPS prior to being demoted to Triple-A Tacoma last month, but his season has taken another disappointing turn.
Greg Johns of MLB.com reports that Montero was diagnosed with a torn meniscus in his left knee and will undergo surgery next week. He’s expected to miss 4-6 weeks, which places his return around midseason.
Montero was hitting .250 (7-for-28) with three doubles, one triple, and two RBI over his first seven games in Triple-A. He has mostly played first base since his demotion, as the Mariners are almost ready to throw in the towel on the idea of using him as a catcher. However, the transition process will have to wait a few weeks.
