Thole has been diagnosed with a "significant" hamstring tear that could sideline him for the entire season, Nick Piecoro of AZCentral.com reports.

EDGE Analysis

According to Piecoro, Thole will seek a second opinion on his injury, but the indication is that surgery is a possible course of action. Despite the loss of Welington Castillo this offseason, Arizona does have a group of serviceable catchers on the roster with Chris Iannetta and Jeff Mathis. Thole, a non-roster invitee, was unlikely to make the Opening Day roster prior to his injury.
