Vladimir Guerrero Jr. had two doubles and four RBIs while George Springer homered to help the visiting Toronto Blue Jays past the Boston Red Sox 9-4 on Tuesday.

The Blue Jays scored all nine of their runs over the third and fourth innings, highlighted by an initial seven-run scoring frame that erased an early 2-0 Red Sox lead.

Kevin Kiermaier also posted a three-hit game, scoring two runs and driving in another for Toronto.

The support was more than enough for starter Kevin Gausman (6-6), whose six innings of work included five strikeouts and helped Toronto snap a seven-game skid.

Rafael Devers (2-for-4) and Tyler O'Neill each homered for the Red Sox, who were held to five hits while losing for just the second time in the past 10 games.

Brayan Bello (7-5) was roughed up for seven runs on five hits and three walks in 2 1/3 innings. Josh Winckowski covered all but two outs the rest of the way, striking out a career-high eight over six innings of relief.

After a 1-2-3 start against Gausman, the Red Sox struck for a pair of quick runs in the second. Devers opened the scoring with a towering homer out to deep right center, his 16th homer of the season.

O'Neill dropped a ball into shallow right over a lunging Guerrero's glove at first base to continue the inning. Masataka Yoshida then lined a double to right and added to Boston's lead at 2-0.

The Blue Jays wasted little time tying the game and more, tagging Bello for a seven-run inning in just a span of eight batters. Kiermaier knocked an RBI single off the glove of Enmanuel Valdez at second, and right fielder Wilyer Abreu's relay throw sailed and led to the second run.

After back-to-back walks, Guerrero crushed a go-ahead, two-run double into the center-field triangle before a Turner grounder and two-run Springer homer into the Red Sox bullpen to bring Toronto in full command at 7-2. It was Springer's sixth homer of the season.

The Toronto lead ballooned to 9-2 against the bullpen on Guerrero's two-run double that bounced into the left-field corner and a subsequent throwing error.

Devers' fan-interfered double to center set up another RBI opportunity for Boston in the sixth, and O'Neill crushed a two-run homer out to deep right, his 16th homer of the season.
