New York has the Toronto Blue Jays' number at Yankee Stadium.
At this point, the Bronx Bombers need all the help they can get.
Andy Pettitte tossed six innings of one-run ball and Curtis Granderson smacked a solo homer in the Yankees' 5-3 win over the Blue Jays to sweep a four-game set.
New York has won 13 in a row and 22 of its past 24 meetings against its AL East rivals from north of the border in the Bronx.
Pettitte (9-9) allowed four hits and three walks to pick up the win for the Yankees, who are six games behind the Boston Red Sox for the AL East lead and 3 1/2 back of the Oakland Athletics for the AL's second wild-card spot.
J.A. Happ (3-3) surrendered four runs on three hits and five walks over 5 1/3 frames for Toronto, which has dropped five consecutive contests.
This contest started after a rain delay of nearly 3 1/2 hours.
J.P. Arencibia led off the fifth with a homer to get the Blue Jays on the board, but the Yankees plated two in the home half and three more in the sixth to surge ahead.
Granderson's leadoff shot and a Vernon Wells RBI fielder's choice grounder gave New York the lead in the fifth.
Three straight one-out walks in the sixth loaded the bases for Eduardo Nunez, who lined a two-run single to center off reliever Brad Lincoln. A Chris Stewart RBI groundout made it 5-1.
A Munenori Kawasaki RBI single and Edwin Encarnacion run-scoring groundout cut the deficit to 5-3 in the seventh. Boone Logan entered from the bullpen with men on first and second, and struck out pinch-hitter Adam Lind to end the inning.
Preston Claiborne tossed a scoreless eighth and David Robertson fired a 1-2-3 ninth to pick up his second save of the season.
