The Byrd Man is back, per FoxSports.com:

The Red Sox, seeking additional depth for their rotation, have signed free-agent right-hander Paul Byrd to a minor-league contract, according to a major league source.

Byrd, 38, is expected to be ready to join the major league staff around Sept. 1. He has yet to pitch this season and will require time in the minor leagues.

This is purely a depth move -- don't expect Byrd to be toeing the rubber tomorrow night. While he could prove valuable in September, that will probably be the only time he will. But still, it's nice to have a little insurance in Pawtucket.
