Francisco Alvarez Injury: Thumb surgery imminent

Alvarez will undergo surgery in the coming days to repair a sprained UCL in his right thumb, Anthony DiComo of MLB.com reports.

Alvarez suffered the injury in late August, but he elected to delay surgery until the offseason and returned to play in early September. The operation could delay Alvarez's offseason workouts a bit, but it should not affect his availability for the beginning of spring training.
