"To fans he's "Doctor K," or simply "Doc." To the record books, he's Dwight Gooden, three-time world champion pitcher for the Mets and Yankees. To Gary Sheffield?

He's just "uncle."

And that's a word Yankees pitchers likely were screaming after Sheffield drove in four runs in the first two games of the Subway Series, powering two homers against his former team as Gooden watched. Sheffield was 3-for-28 with no home runs coming into Friday's game.

"It's a great feeling sitting down here," Gooden said, relaxing by the third-base line during yesterday's 6-2 Mets win at the Stadium. "I know he was struggling a little bit coming in here, but this is probably just what he needed to get going. The rivalry, the fans. And for me to watch him do it, that is a big thrill."

It was just as thrilling for Sheffield. "I was very excited about that," said Sheffield, who later was to join his uncle at the Miguel Cotto vs. Joshua Clottey welterweight bout at the Garden. "I saw him sit down and saw the fans greeting him and I said, 'I got to get one where I can point at him.' ""
