Sox acquire infielder Hannahan

Multiple team sources say that the Red Sox have acquired infielder Jack Hannahan from the Mariners. It's not clear what the Red Sox will send in return. Pawtucket Red Sox radio announcer Dan Hoard broke the news on Twitter.

Hannahan, 30, who has spent his entire season with Triple-A Tacoma, hitting .228, is expected to head to Pawtucket on Friday.
