Carrasco injured his right leg during a performance in the 4th inning today.  He managed to make it off the field on his own and was rushed to a hospital, where they operated on his immediately.  Seems there's a good chance he'll miss the entire season.

UPDATE 4/17 @ 12:01pm - Seems the mascot injured his right Achilles tendon while doing a back-flip during his entrance before the start of the bottom of the 4th.  The latest report doesn't make any mention of a surgery.
