TORONTO -- Andy Pettitte keeps winning and so do the New York Yankees.
The 40-year-old left-hander pitched in his 420th game as a Yankee on Friday and went 7 1/3 innings to earn his third win of the season as New York defeated the Toronto Blue Jays, 9-4.
After skipping his previous starts because of back spasms, Pettitte (3-0) held the Blue Jays to six hits and three runs, two on a home run by Jose Bautista in the sixth inning before a crowd of 40,028 at Rogers Centre.
"I felt like I hadn't pitched all year, to tell you the truth," he said. "Just trying to control my emotions and stuff like that. It took me a few innings to settle in.
"I felt good tonight. I didn't have any problems with (his back) at all. I want to make sure that it's not anything that I aggravate or flare back up."
It was the 248th win of Pettitte's career, 211 with the Yankees. It is the third time he has started a season 3-0.
"Very pleased," manager Joe Girardi said. "I thought he was a little strong his first inning. It took him the first inning to find his rhythm and then he was really good after that."
Travis Hafner, Lyle Overbay and Vernon Wells hit solo home runs in support of Pettitte in the opener of a three-game series.
Wells and Overbay, former Blue Jays who were booed when they came to bat, contributed to a 13-hit Yankee attack.
"They're passionate and they love getting on the opposing team," Wells said. "And especially if you were a Blue Jay, they enjoy it even more. It comes with the territory."
The Yankees led 2-1 after one inning. Robinson Cano doubled with one out against right-hander Brandon Morrow (0-2), Kevin Youkilis was hit by a pitch, and Hafner doubled past first base for the first run. Wells grounded out to second to score the other run.
Rajai Davis led off the home first with a triple to left center. He scored on Melky Cabrera's groundout to second.
New York (9-6) tacked on three runs -- two of which were unearned -- in the third. Hafner hit his fifth homer of the season on a 3-1 pitch with one out. Wells singled and Ichiro Suzuki doubled. Eduardo Nunez flied out to center and center fielder Colby Rasmus was charged with a two-run error when his throw home bounced away from catcher J.P. Arencibia and into the Yankees dugout allowing both runners to come home.
"The big play is the ball we throw away, it scores two runs and that changes the complexion of the game," Blue Jays manager John Gibbons said. "You fall too far behind guys like Pettitte, the good pitchers, they don't make enough mistakes where you can get back at them. At his age its special what he's still doing."
That made it 5-1 in favor of the Yankees.
The Blue Jays (7-10) scored two of their runs on Bautista's fourth home run of the season in the sixth inning that followed a single by Cabrera to snap a 0-for-13 streak. Their final run came on the sixth homer of the season by Arencibia against Shawn Kelley with two out in the ninth.
Morrow was hit hard, allowing nine hits, including two home runs and seven runs (five earned) over 5 1/3 innings. The Yankees had seven extra-base hits against Morrow, whose ERA increased to 5.57.
"I fell behind early in the count the first few batters and wasn't locating my fastball well," Morrow said. "I guess I could throw more pitches in the bullpen or just bear down a little bit quicker in the first inning. I felt all right coming out -- just was leaving some pitches up."
Morrow retired the first batter of the sixth before Overbay hit his second homer of the season and Nunez followed with a double.
Left-hander Brett Cecil entered the game and allowed an RBI triple to Brett Gardner who scored on a ground out. Cecil also allowed Wells' fourth homer of the season in the seventh.
"Andy is remarkable," Wells said. "I've had a chance to see him for a long time and he's the same guy he was 10, 12 years ago. It's fun to watch and it's a pleasure to watch an individual that's been around this long and still continues to have success."
NOTES: Bautista (back spasms) was back in the Blue Jays lineup on Friday as the designated hitter after missing the previous four games. He will probably be used as a DH during the three-game series against the Yankees on the artificial turf at Rogers Centre. ... First baseman Overbay and outfielder Wells lead a contingent of former Blue Jays who are with the Yankees. It also includes infielder Jayson Nix and outfielder Ben Francisco. ... Left-hander Mark Buehrle (1-0, 7.31 ERA) will start Saturday for the Blue Jays against Yankees right-hander Hiroki Kuroda (2-1, 2.87 ERA).
