Roy Halladay blanked the Nationals for four innings Wednesday to win for the second time this spring. Halladay, apparently getting ornery in his old age, threw behind Tyler Moore today in obvious retaliation for Stephen Strasburg hitting Chase Utley the previous inning. He was plenty effective, allowing just a couple of hits and walking one. His velocity still isn't quite as good as hoped, but his spring is going about as well as could have been expected.
