NEW YORK -- For the first four innings, the Yankees looked late at the plate -- and it wasn't because they were tired from Old Timers' Day festivities.
Nope, they were behind on all those 96 mph fastballs Rockies rookie Juan Nicasio was zipping over the corners, so New York made an adjustment the second time around.
"We started looking for the fastball more," Jorge Posada said.
The adjustment paid off in the fifth. Posada followed Nick Swisher's two-run homer with a drive of his own, and Eduardo Nunez hit a tiebreaking single in the seventh after shortstop Troy Tulowitzki made an error, leading the Yankees to a 6-4 win over Colorado.
Mark Teixeira also homered for New York and Alex Rodriguez drove in a run in his sixth straight game.
Ty Wigginton connected twice for his second multihomer game this week and Chris Iannetta also homered for Colorado.
It was New York's first series win against the Rockies since sweeping a three-game set at the old Yankee Stadium in 2004. New York improved to 22-4 in day games.
"It was a great day overall," manager Joe Girardi said.
With a handful of pitchers who have thrown no-hitters, including Don Larsen, at Yankee Stadium for the 65th Old Timers' Day, Nicasio did not allow a baserunner until Robinson Cano singled with one out in the fifth.
Nicasio had been falling behind batters all game yet fought back nicely with his crisp fastball, but he left a 3-1 pitch over the middle of the plate to Swisher, the next batter after Cano, and the switch-hitter drilled it into the right-field stands.
"In the first two innings he was consistently 95, 96 (mph). Then starting in the third, fourth, fifth inning, the velocity started dropping down to 92, 93," Swisher said. "I think that has a little bit to do with it."
Posada got the crowd of 47,894 really rocking with his eighth homer of the year to make it 3-all. It was the third time the Yankees have connected for two in a row this season.
"It might have distorted his focus a bit," Rockies manager Jim Tracy said of the 24-year-old Nicasio. "You have to remember that he's had about six or seven career starts."
Boone Logan (2-2) got three outs in the seventh, David Robertson was perfect in the eighth and Mariano Rivera struck out the side in the ninth for his 20th save.
Before the game, Joe Torre sat at a microphone wearing pinstripes for the first time in nearly four years, and blurted out the answer to a question before it was finished being asked.
"No, I'm not doing that!" the 70-year-old Torre said, as he was being asked whether he had any desire to follow 80-year-old Jack McKeon back to the manager's chair.
Lou Piniella, who joined Torre as a first-timer at the Old Timers' Day, was equally emphatic about being satisfied with his decision to retire from his job as a big league manager. He called it quits as skipper of the Chicago Cubs last summer.
