Andy Pettitte (16-9, 2.43) vs. Tom Gorzelanny (0-0, 0.00). Gorzelanny makes his first big-league start tonight. He's another lefty, but not a crafty one along the lines of Zach Duke or Paul Maholm - Gorzelanny can bring the heat. He's the least polished of the three young lefties, however.
Andy Pettitte has quietly had a ridiculously good season. How ridiculously good?
