Casey Janssen insisted it wasn't the three-game layoff. Robinson Cano was the problem.
Cano greeted the Blue Jays reliever with a go-ahead, two-run double in the seventh inning to exceed 100 RBIs for the second consecutive season and help the New York Yankees rally for a 6-4 victory over Toronto on Saturday.
"I didn't feel rusty," Janssen said. "I felt good enough to pitch and like I said, give him some credit. My arm is fine."
Cano lined a 2-2 pitch from Janssen to the wall in centre field to score Curtis Granderson and Alex Rodriguez, back in the lineup after missing a week with a sprained left thumb.
Janssen hadn't pitched since Tuesday, when he extended his scoreless stretch to 16 2-3 innings. He was out with tightness in a back muscle.
Ricky Romero (13-10) was cruising along after giving up a two-run homer to Francisco Cervelli and an RBI single to Eduardo Nunez in the third until he hit Granderson in the back with a curveball with one out in the seventh and walked Rodriguez.
A .309 career hitter, Cano was motivated by the walk to A-Rod.
"Every time I see they walk a guy in front of me, that pumps me up," Cano said, "and I say, 'Come on, now is a situation where you've got to show them they've got to pitch to the guy in front of you.'"
After Cano's hit, Nick Swisher ended Janssen's scoreless streak that started on July 26 with an RBI single, making it 6-4. Cano had the tiebreaking hit in Friday night's 3-2 win, a single in the fifth. He has 101 RBIs this season.
"He's a good hitter. (I) didn't have to give in 2-2 but definitely wanted to throw an aggressive pitch and he hit it," Janssen said. "It was a cutter. A little bit flatter than I wanted it."
The Yankees improved to a major league-best 36-9 in day games and ended Romero's winning streak at six straight decisions. His last loss came against New York on July 16.
"I thought that Ricky did a heck of a job. It was one of those games he deserved to win," acting manager Don Wakamatsu said. "I felt that he put Janssen in a situation to save the outing in the seventh, but it didn't work out."
Elsewhere in the AL, it was: Oakland 3 Seattle 0; Detroit 9 Chicago White Sox 8; Boston 12 Texas 7; Tampa Bay 6 Baltimore 3; Kansas City 5 Cleveland 1; and L.A. Angels 10 Minnesota 6.
At New York, Rodriguez returned with a taped left thumb after missing six games. With Derek Jeter getting a day off after a night game and Mark Teixeira out for a second straight game because of a sore knee, A-Rod batted third for the first time since 2008. He went 1 for 3, striking out in the fifth after getting ahead in the count 3-0, and walked.
Boone Logan (5-2) relieved Bartolo Colon with one out in the seventh and got two outs for the victory.
David Robertson tossed a perfect eighth. With Mariano Rivera and Rafael Soriano unavailable after each pitched two straight nights, Robertson gave up a hit in the ninth before finishing for his first save this season and third of his career.
Toronto injury replacement Dewayne Wise tripled in his first at-bat after entering the game for Eric Thames, who left because of dizziness after striking out looking in the first. Wise hit his first homer of the season in the fifth, a tiebreaking shot.
Blue Jays shortstop Yunel Escobar also left because of an injury, pulling out before the bottom of the fifth with a jammed left wrist. He said X-rays were negative but he was sore and wouldn't play Sunday.
"Just day to day right now," Wakamatsu said.
Adam Lind connected off Colon, and Jose Bautista drove in a run for the fourth straight game for Toronto, which built a 4-3 lead against Colon in the fifth.
Colon came in 6-1 with 1.88 ERA in eight day starts, but he struggled at times in his 6 1-3 innings, giving up four runs and seven hits. He struck out seven and walked one, throwing a season-high 107 pitches.
Lind led off the second with his 24th home run, Edwin Encarnacion and Kelly Johnson each had a single and Encarnacion advanced to third on Brett Lawrie's fielder's choice.
J.P. Arencibia gave Toronto a 2-0 lead with a sacrifice fly.
The Yankees scored three times with two outs in the bottom half. Nunez laced an RBI single and Cervelli followed with a two-run homer.
The Blue Jays got a run right back when Wise tripled into the right-field corner and scored on Bautista's single.
Colon struck out his last batter of the third and fanned the side in the fourth. Wise homered into the Yankees' bullpen in right-centre with one out in the fifth for a 4-3 lead.
