Another issue for the Yanks could be this quote from Omar Minaya, GM of the Expos:
I think Vazquez is one of the better young pitchers in the game. When he goes out there, he gives you everything. He's got one of the higher pitch counts in the game. That means he wants to be out there.
Does it mean he wants to be out there? Or does it mean he's going to break down soon? Here's how STATS inc described AJ Burnett before 2003:
He was among the most durable starters in the majors, ranking behind only Randy Johnson in total pitches thrown and pitches per start through the first five months.
In case you weren't paying attention, Burnett blew his elbow out after only 4 games this year. Could the same be in store for Vazquez?
