The most overlooked bright spot of this Nationals season delivered again last night. In Harrisburg, Brad Peacock took the mound with a 2.13 ERA, and then he lowered it by allowing New Hampshire one run in seven innings. Peacock, 23, has been a breakout star at Class AA, becoming one of the Nationals very best prospects this season.

After building a minor buzz in the Arizona Fall League last year, Peacock has stood out in Harrisburg this year. In 62 innings, he has a 2.03 ERA with 82 strikeouts and 13 walks.

The Nationals drafted Peacock in the 41st round in 2006, and he has always had reasonably high strikeout numbers. He's taken off this season, Nationals director of player development Doug Harris said, after making an adjustment to his delivery.

With Harrisburg pitching coach Randy Tomlin and pitching coordinator Spin Williams, Peacock made adjustments that gave him both better command of his fastball and more deception in his delivery.
