Vasquez is most remembered in the Bronx for his 2nd half of the season and the HR allowed in the ALCS against the Red Sox in 2004. After being acquired by the Braves in a 5 player trade (Logan, Vasquez to Yanks and Vizcaino, Cabrera, Dunn to Braves), he's excited for another opportunity and prove himself as a Yankee.
For all of you that's worried about how he will react to AL hitters, he did admit that he was injured for the 2nd half of the '04 season, so there's no worry. He did well in the 1st half when he was healthy. Yankees fans only think of his struggles, and not his Top 3 placing in the NL Cy Young Award race. As a #4 Starting Pitcher, he isn't pressured to lead the rotation, and will eat up innings effectively and strike guys out.
Along with strong offense behind him, here are his projected stats for the 2010 season.
W-L : 17-7
ERA : 3.72
IP : 213
SO : 204
He may be the best #4 SP in MLB this season.
