CHICAGO -- Felix Doubront had not started a game in the major leagues since Sept. 20, 2014, with the Chicago Cubs, but he made the most of his audition as a starter with the Toronto Blue Jays.

Led by 6 2/3 strong innings from Doubront, the Blue Jays beat the Chicago White Sox 2-1 on Tuesday at U.S. Cellular Field, splitting the first two games of a four-game series.

Doubront (1-0) got the win after allowing just one run on six hits and striking out eight. Toronto third baseman Josh Donaldson led the way offensively by hitting a solo home run in the third inning that turned out to be the winning run.

"I'm so glad to be here again, getting this opportunity with this team," said Doubront, who was cut by the Cubs on March 28 and signed by Toronto April 2. "My arm feels great. My shoulder feels good. I think that's the best part, being healthy and throwing the ball 100 percent."

The Blue Jays' bullpen pitched 2 1/3 scoreless innings, capped by right-hander Roberto Osuna's scoreless ninth for his fourth save. Right-hander Bo Schultz and left-hander Aaron Loup also had scoreless relief appearances.

Chicago left-hander Jose Quintana (4-8) made his eighth consecutive quality start, but took the loss. He held Toronto to two runs on four hits in eight innings, struck out eight and didn't walk a batter.

Coming into the game, Quintana was tied for third in the American League with 12 quality starts and was third in the AL since 2013 with 50 quality starts, trailing only teammate Chris Sale (57) and Detroit's David Price (54).

This outing summed up his season. It was the 13th time in Quintana's 17 starts that he received two runs of support or less from White Sox hitters. Chicago hasn't produced more than four runs in a home game since May 9, a span of 24 games.

"You get to the point where it's just too hard for these guys to try to win 2-1 and their degree of being able to go out there and pitch like that, there's no room for error," White Sox manager Robin Ventura said. "So, for (our pitchers), it's not giving them a big lead and they sit there and kind of play with it."

The bottom of the ninth was a good example.

Still trailing by a run, the White Sox got the tying run to third after an infield single by shortstop Alexei Ramirez, a sacrifice bunt and a wild pitch by Osuna. Pinch hitters J.B. Shuck and Conor Gillaspie each popped out to foul territory to end the game.

"We haven't had that moment where a number of us are hot, so we're still kind of waiting on that to happen and we've got to find ways to scratch and claw through," Chicago catcher Tyler Flowers said. "Tonight, we should have done a little bit better."

Toronto took a 1-0 lead off Quintana in the first by manufacturing a run after a lead-off single by shortstop Jose Reyes. The White Sox tied it 1-1 in the second with a two-out double by third baseman Gordon Beckham and an RBI single by rookie second baseman Carlos Sanchez, who was hitting just .162 coming into the game.

Donaldson put the Blue Jays back in front 2-1 the same way he did Monday, only this time his solo homer went to right field instead of left. Also like Monday, the starting pitchers were each left-handed and tough to solve.

Doubront struck out five through the first five innings, and Quintana struck out seven through the first five frames, including five in a row between the end of the fourth and the fifth.

"We're used to slugfests," Toronto manager John Gibbons said. "It's nice to play a game like that and come out on top."

NOTES: White Sox manager Robin Ventura will keep his rotation the same for an upcoming weekend series against the Chicago Cubs at Wrigley Field. The scheduled starters are LHP Carlos Rodon, LHP Chris Sale and LHP Jose Quintana, in that order. ... Blue Jays manager John Gibbons said LHP Felix Doubront has a chance to earn a longer stint in the rotation. Doubront's start Tuesday was his first start for Toronto. He hadn't started in the majors since last season with the Cubs. ... Toronto RHP Aaron Sanchez made a rehab start Tuesday in the rookie-level Gulf Coast League, allowing two runs in two innings. Gibbons said the tentative plan is to have Sanchez make two more two-innings starts before transitioning to more of a regular schedule with five days off between outings. ... Chicago RHP Nate Jones (Tommy John surgery in July 2014) is expected to start a rehab assignment in the minors sometime this week.
