From the official site:

It had been more than three years since Andy Pettitte had set foot in Yankee Stadium. Not much had changed.

The ballpark was colder than Pettitte had been accustomed to, perhaps, but the painted blue line still led to the Yankees' clubhouse; the photo on the scoreboard, an image of the left-hander donning his old "NY" cap, seemed just right.

"I definitely missed it," Pettitte said on Thursday, as he was officially reintroduced as a Yankee. "It's just a special place to play and to pitch. Now just thinking about it, this is where it all started for me.

And about Clemens:

Andy Pettitte's sense is that Roger Clemens will decide to pitch in 2007. If it happens, Pettitte wants it to be as a Yankee.

"Would that be great," Pettitte said. "Does he know that I would love that? Of course."
