Jose Bautista and Ryan Doumit each hit two-run home runs as the Pirates' 19-hit assault blew away the New York Yankees, 12-5, tonight before a standing-room-only crowd of 38,867 -- third-largest in PNC Park history -- in the teams' first Pittsburgh meeting since the 1960 World Series.

It also was the Pirates' first victory in seven interleague meetings with the Yankees, the first since Bill Mazeroski took Ralph Terry deep at Forbes Field 48 years ago to win their third championship.

Mazeroski, who did not attend the first six interleague meetings at Yankee Stadium, threw out the ceremonial first pitch and drew a standing ovation.

The hit total matched the Pirates' season high in a 14-4 romp at St. Louis.

Tom Gorzelanny had a bizarre start but, officially, a quality one: He limited New York to three runs over six innings despite six hits and five walks. Only 47 of 99 pitches were strikes, a stunningly low ratio to reach nearly three figures in pitches.

Still, he evened his record at 6-6, leading the staff in victories.

Tyler Yates and Damaso Marte pitched scoreless relief until struggling Franquelis Osoria gave up two in the ninth.

Beforehand, despite more media and more fans at batting practice than usual, the Pirates tried to downplay the difference between these three nights and any others.

"It's the Yankees, so there's going to be something special there," manager John Russell said. "It's just another series. We've still got to go out there and do our jobs."

"It's not a big deal to me," Yates said. "No different than when we go to New York."

The Pirates pounded on New York starter Darrell Rasner right away, Nate McLouth drilling his first pitch to the fence in right-center for a double. A wild pitch and Freddy Sanchez's single brought him home, Sanchez taking an extra base on left fielder Justin Christian's bobble. One out later, Adam LaRoche's liner into center made it 2-0.

Another run came in the third. Sanchez's one-out single was followed by Bay driving an RBI double into the North Side Notch.

The Yankees stranded three runners in the first three innings but got their first run in the fourth. Jorge Posada doubled after two outs, and Robinson Cano singled him home to cut the Pirates' lead to 3-1.

That inning could have gone much worse for Gorzelanny, as he then gave up a single and, remarkably, walked Rasner a second time to draw loud boos. But he got Melky Cabrera to bounce into an inning-ending forceout.

Then, the Pirates poured it on, to the delight of a crowd that was cheering and chanting as loud as any in recent memory.

Doug Mientkiewicz opened the fourth with a single, and Bautista sent a 1-2 changeup into the left-field bleachers to make it 5-1. It was Bautista's ninth home run, his fifth in the past nine games.

Doumit, back after missing five games to a concussion, lined Rasner's 1-0 fastball into the seats beyond right-center. It was his 10th home run, his fifth in the past eight games.

Next, LaRoche tripled off the top of the fence in center, just the third of his career, then scored on a wild pitch. It was 7-1.

A two-run double by Christian in the sixth pulled the Yankees within 7-3, but Gorzelanny finished with an out in retiring pinch-hitter Jose Molina.

Yates gave up a leadoff double in the seventh, but he put down the next two batters and Marte fanned Jason Giambi.

The Pirates kept adding.

Bay opened the seventh with a double off LaTroy Hawkins, and Doumit and LaRoche followed with singles, the latter scoring Bay. Mientkiewicz's sacrifice fly made it 9-3.

Nyjer Morgan's two-run double in the eighth, followed by a Doumit double, accounted for the rest of the offense.

LaRoche finished 3 for 4 with two RBIs. Doumit and Sanchez also had three hits each, Sanchez's continuing a 7-for-17 roll that looks as promising as any he has had in a while.

Zach Duke will face Joba Chamberlain tomorrow night.
