MINNEAPOLIS -- Andy Pettitte turned in another ageless performance by pitching six scoreless innings and the New York Yankees hit four home runs to beat the Minnesota Twins 6-3 Monday night and extend their AL East lead.

The Yankees took a 1½-game edge over Baltimore, which split a doubleheader with Toronto. This is the first time since Sept. 2 their margin has been more than one game.

Curtis Granderson hit his 40th home run and Nick Swisher, Raul Ibanez and Eric Chavez also homered as New York won for the 10th time in 12 games.

Pettitte (5-3) hasn't given up a run in 11 innings since rejoining the rotation last week.

Swisher's two-out, two-run shot in the first inning off Liam Hendriks (1-8) made it 3-0.
