Who says Josh Beckett has lost a little off his fastball?

With statistical studies claiming that his average velocity has dropped from 94.7 miles per hour in his first year with the Red Sox (2006) to 91.5 this year, Beckett showed Tuesday that he still has gas left in his tank.

On his 32d birthday, Beckett combined with Rich Hill and Alfredo Aceves to throw a four-hit shutout, 5-0, over the Seattle Mariners at Fenway Park, with Beckett recording nine strikeouts.

"He belongs on that hill,'' said manager Bobby Valentine after the Sox closed out a six-game home stand with five consecutive wins. "It's his saddle, and he looked very comfortable in it.''
