Starting pitchers this afternoon were righthander Aaron Sanchez (Toronto) and righthander Corey Kluber.
Sanchez was 15-2 this season with a 3.00 ERA and 161 strikeouts in 192 innings.
His ERA was the lowest this season in the American League.
In the ALDS, Sanchez pitched once against the Texas Rangers, giving up six runs in 5 2/3 inning.
This season he faced the Indians once and then had a no-decision, throwing four innings.
Kluber pitched on three days rest today, which he never did before in his career.
This season, Kluber was 18-9 with a 3.14 ERA and 227 strikeouts in 215 innings.
During the season, he pitched twice against Toronto and then was the losing pitcher in one game and had a no-decision in the other one.
In the ALCS, Kluber started Game 1 against Toronto last Friday.
He then held Toronto scoreless in 6 1/3 inning and struckout six batters to become the winning pitcher.
In the top of first inning, Toronto-starter Aaron Sanchez retired the side, including striking out the first two batters he faced.
Corey Kluber also retired the first two batters he faced, but then gave up a single to Edwin Encarnacion, but he was then forced out.
Toronto got its second basehit in the bottom of the second inning when Michael Saunders singled with one out, but he also was forced out.
In the top of the third inning, Cleveland was the first team to get into scoring position.
Tyler Naquin led off with a double, then moved to third base on a sacrifice bunt by Roberto Pérez.
However, he stranded there when two grounders followed.
It was then Toronto that opened the score in its third at bat.
Corey Kluber struckout the first two batters, including another strikeout for José Bautista.
But hereafter, Josh Donaldson homered into left-centerfield to give the Canadian squad an 1-0 lead.
In the bottom of the fourth inning, Toronto got its first two batters on base.
Corey Kluber walked both Troy Tulowitzki and Russell Martin
Hereafter, Kluber struckout Michael Saunders, but he then gave up Toronto's second run when Ezequiel Carrera followed with a runscoring single.
Kluber then also struckout Kevin Pillar and Ryan Goins, but Toronto had taken a 2-0 lead.
Cleveland got another runner in scoring position in the top of the fifth, then scored its first run.
With one out, Coco Crisp walked and he moved to second base when the third strike for Tyle Naquin ended in a wild pitch.
Crisp then scored the first Cleveland-run when next batter Roberto Pérez doubled.
Pérez was left behind when Toronto's third baseman Josh Donaldson made a nice play on a hard grounder by Carlos Santana that ended the at bat.
When the ball would have gone through the infield, the score probably would have been tied at 2-2
After giving up runs in the third and fourth inning, Corey Kluber had a fine inning in the bottom of the fifth.
For the first time, he then retired the side, including a strikeout Josh Donaldson.
Aaron Sanchez retired the Cleveland-side for the third time in the top of the sixth inning.
In the bottom of the sixth, Dan Otero took over the pitching for Cleveland-starter Corey Kluber.
The day before, in Game 3, Otero was one of seven relievers that were used by Cleveland in the 4-2 victory.
Otero then took over in the first inning when starter Trevor Bauer had to leave with a bleeding right pinkie finger.
Otero, who threw 1 1/3 inning yesterday, gave up a lead-off single to Troy Tulowitzki, who was then forced on a grounder by Russell Martin.
A following single by Michael Saunders led to two baserunners, but they both stranded.
In the top of the seventh, Toronto-starter Aaron Sanchez also was relieved.
Brett Cecil took over and retired the side, including two strikeouts.
Toronto got on base again in its seventh at bat off of new pitcher Bryan Shaw, who also was one of the successful relievers in Game 3.
He gave up a lead-off single to Ryan Goins, then got runners on first and third base when José Bautista reached on an error.
To set up a force play at every base, Josh Donaldson was walked intentionally.
That set-up failed, as Edwin Encarnacion followed with a 2-run single.
Donaldson was eliminated at third base trying to advance from first base and on the throw, Encarnacion ended up on second base.
That led to a pitching change.
Shaw was replaced by Mike Clevinger, who initially was mentioned as possible starting pitcher for today's game.
Clevinger saw Encarnacion advance to third base on a wild pitch, but then got two grounders.
Toronto added another run in the bottom of the eighth inning.
With one out, Ezequiel Carrera tripled and scored on a sacrifice fly by Kevin Pillar.
In the top of the ninth, closer Roberto Osuna retired the Cleveland-side, including two strikeouts to end the game.
With that, Toronto avoided a sweep and forced a fifth game.
