Jeff Locke spoke of no tweaks. No adjustments no changes in methods nothing to explain the increase in bases on balls issued since the All-Star break.

"My approach or mentality nothing like that's changed" Locke said. "There's no reason for me to change. I made the All-Star team."

Locke walked four batters in four innings Thursday night against the San Francisco Giants. The Pirates scored seven runs in the fifth inning on the way to a 10-5 win bailing out Locke but he did not return for a chance to earn the win in the fifth despite a 10-3 lead.

Locke walked 47 batters in 109 innings in the first half of the season. In 342/3 second-half innings he has walked 25. His walks issued per nine innings has increased from 3.9 per nine in the first half to 6.5 in the second.

Locke said he felt good and his velocity Thursday night when his fastball reached 94 mph reflected that.

"Obviously there's a lot of frustration when you want to be more efficient or you want to be better than your performance shows but that's part of it too" Locke said.

"I could have had the same first half as I'm having in the second half right now. It's nothing I'm going to lose any sleep over."

Locke has credited some of his success this season to an increased use of his two-seam fastball a strength of his. He tries to throw the two-seamer on the edges of the plate to prevent the pitch which moves away from right-handed batters from tailing into the heart of the strike zone.

"I don't think I really ever do miss middle" Locke said. "I miss off the plate on both sides. That's going to come back and bite you when you can't get it back in.

"If I could go out there and just pump the strike zone I would. I think sometimes trying to be too fine and realizing that it is really hard to hit a fastball down the middle. Sometimes giving hitters a little bit too much credit."
