TORONTO -- R.A. Dickey's knuckleball was working so well, he figured he'd throw a complete game.
Those hopes ended when a tight muscle brought his outing to an early end.

"There was no reason to push it," Dickey said of his soreness. "We had a lead and it had progressively gotten a little bit worse throughout the game."
Dickey (2-2) allowed two hits, both singles. The reigning NL Cy Young Award winner walked one, struck out a season-high seven and lowered his ERA from 5.82 to 4.30.
"I had a knuckleball tonight where I would have thrown a complete game," Dickey said, "so it was unfortunate that (the injury) acted up on me."
White Sox catcher Tyler Flowers had never faced a knuckleballer before, and didn't fare well in his two at-bats against Dickey.
"For me it was kind of like someone turned off the lights every couple feet as it was coming to you," Flowers said. "It was moving that much, at least the ones to me were."
Dickey said his back first felt sore during his start at Kansas City last Saturday, but was able to pitch another 1 1/3 innings against the Royals.
"It got better over the course of the week, enough so that I felt comfortable taking the ball," he said. "Hopefully it will continue to get better in between these starts."
Blue Jays manager John Gibbons called Dickey's start "outstanding," and said he didn't think the knuckler would have to miss any time.
"He's a tough guy," Gibbons said. "I'm sure we'll see him in five days."
Dickey said he was "optimistic" that he could make his next scheduled start, Tuesday at Baltimore, but was cautious about pushing himself.
"I just don't want it to linger for months," he said.
Dickey retired the first 11 White Sox batters before Alex Rios hit a two-out single to center in the fourth. Rios went to second on a wild pitch and Paul Konerko walked, but Adam Dunn struck out to end the inning.
Gibbons and Blue Jays trainer George Poulis came to the mound after Dickey struck out Dewayne Wise for the second out of the sixth. After a brief discussion, Dickey remained in the game, getting Jeff Keppinger to fly out to left.
Dickey appeared to be rubbing his upper back as he left the dugout and walked to the clubhouse at the end of the inning.
"I hadn't gotten up and sat down so many times since I first felt it, so it was just getting tighter and tighter," Dickey said.
Davis led off the first with a single and stole second and third on consecutive pitches before scoring on Edwin Encarnacion's two-out hit to left.
One out later, with the infield drawn in, Bonifacio scored when Dunn couldn't handle a grounder by Munenori Kawasaki. Davis followed with an RBI double.
The White Sox spoiled Toronto's shutout bid in the eighth. Alexei Ramirez chased Rogers with a one-out single and scored when Flowers hit a two-out double off Loup. Wise grounded out to end the threat.
Sale (1-2) gave up a career-high eight runs in his previous start on Sunday at Cleveland, but was sharper in this one. He allowed three runs, two earned, and four hits over seven innings. He walked one and struck out six.
"He threw fine, gave up a couple hits here and there but stuff-wise he was good," White Sox manager Robin Ventura said. "Against R.A. that's just tough luck, because he had it going."
Sale is 2-7 with a 5.83 ERA in his past nine road starts going back to last season.
"It's early in the season but it was a game we really needed against one of the top pitchers in baseball," Gibbons said. "A win does wonders. I don't care what time of year it is."
White Sox outfielder Dayan Viciedo left in the eighth with a strained muscle in his left side, suffered when he swung and missed on a pitch from Rogers. He'll be evaluated Friday when the team returns to Chicago to begin a three-game series with Minnesota.
