St. Louis Cardinals right-hander Justin Masterson was shelled for five runs in two innings of work in his last start Friday vs. the Baltimore Orioles, prompting him to tweak his mechanics with the aid of the team's coaching staff and peers.

"It wasn't exactly what I wanted it to be," Masterson said of his short outing in an story. "We don't feel that far off either. Last outing, I felt really good about getting through pitches. This one didn't feel as crisp. But I think being able to dissect both of them as we go should lead to a better next outing."

Manager Mike Matheny and staff ace Adam Wainwright are working with Masterson, who is just one year removed from an All-Star season, in an attempt to right the ship.

"Right now, he's trying to get it in the right place, which doesn't allow him to let it eat," Matheny said. "Once he gets a good feel with where he is mechanically, I think that allows him to ramp up and use his lower half a little bit better."

Masterson, who boasts an ugly 5.94 ERA and 1.72 WHIP splitting innings between the Cleveland Indians and Cardinals this season, is scheduled to get the ball Wednesday in Miami.
