Josh Donaldson homered to give Toronto a long-awaited lead, and the Blue Jays finally broke through with the bats, beating the Cleveland Indians 5-1 on Tuesday to avert a sweep in the AL Championship Series.
The Indians still lead the matchup 3-1, but Donaldson and a poised Aaron Sanchez handed them their first loss of this postseason.
Edwin Encarnacion later hit a two-run single, a welcome sight for a raucous Rogers Centre crowd that had fallen silent watching its team reach the brink of elimination because of a slumbering offense.
Donaldson's solo shot to left-center field off Corey Kluber in the third put the Blue Jays ahead for the first time all series. Two innings after that, the star third baseman made an outstanding diving stop to preserve a one-run edge.
Sanchez, the American League ERA champion, allowed a run and two hits in six innings, and the bullpen finished with three perfect innings.
Cleveland will try again Wednesday to win to earn its first World Series trip since 1997, but the big concern for the Indians coming into the series — an injury-riddled rotation — still lingers.
Kluber was starting on three days' rest for the first time in his career, and in Game 5 Cleveland will send lightly used rookie Ryan Merritt to the mound against Marco Estrada.
Kluber hadn't allowed a run in either of his first two starts this postseason. Donaldson, the reigning AL MVP and sporting a still freshly shaved face, opened the scoring with his first home run of these playoffs.
The wild-card Blue Jays made it 2-0 in the fourth when Ezequiel Carrera's blooper fell between three Cleveland fielders in left-center for an RBI single.
Roberto Perez hit an RBI double in the fifth off Sanchez. Carlos Santana's two-out grounder to the left side might have had a chance to score him, but Donaldson made the play.
The Indians didn't have another baserunner after that. Brett Cecil, Jason Grilli and Roberto Osuna pitched an inning each in relief for Toronto.
Taking no chances, Blue Jays manager John Gibbons brought in Osuna, his closer, in a non-save situation to finish off Cleveland.
The Indians were trying to become the third team to sweep a Division Series and Championship Series in the same postseason. The 2007 Colorado Rockies and 2014 Kansas City Royals both did it.
Cleveland had won nine in a row, including three straight over Boston in the ALDS.
The Indians had a chance to take the lead in the third when Tyler Naquin hit a leadoff double and went to third on a sacrifice. Sanchez retired Santana on a soft grounder with the infield in, and then Jason Kipnis also grounded out.
Kluber was pulled after 89 pitches. He allowed two runs and four hits in five innings.
