Brian Butterfield hobbling a bit again this spring training.  The third base coach for the Red Sox has had knee replacement surgery again.

Last year the Orono native had his left knee replaced and this winter he had the right one done.

Butterfield is 58 years old and is considered one of the best coaches in Major League Baseball.

Butter says he’ll be ready to go by the regular season and he plans to stay coaching for a long time to come.
