Angels' C.J. Cron: Undergoes thumb surgery Tuesday

Cron underwent an arthroscopic procedure to address a left thumb impingement Tuesday.

Analysis:

Cron was apparently experiencing some pain at the base of his thumb, although it's unclear how and when the injury presented itself. The first baseman is expected to be cleared for full activity in 6-to-8 weeks, which should keep him from missing any time during spring training.
