WEEI: Swihart Will Be Called Up After Hanigan Fractures Right Knuckle

Ryan Hannable, WEEI:

After losing starter Christian Vazquez during spring training to Tommy John surgery, new starter Ryan Hanigan went down Friday night with a fractured knuckle with surgery likely being needed.

Manager John Farrell said he will be out a "substantial" amount of time.

A source tells WEEI.com's John Tomase, Blake Swihart will be the guy called up to replace Hanigan, which leaves Sandy Leon and Swihart as the Red Sox' catchers.

Swihart is hitting .338/.392/.382 for Pawtucket.
