Yamamoto - who had thrown a complete game last week in a game two win before helping the team level the series in Saturday’s pulsating game six win in Toronto - was named World Series Most Valuable Player.
“I was not sure I could pitch tonight until I went to the bullpen tonight, but I’m glad I was able to,” Yamamoto said.
“I did everything I could do, everything I was supposed to do, and I’m so happy that I was able to win this with these teammates.”
The Dodgers are the first team to win back-to-back World Series titles since the New York Yankees completed a hat-trick of titles in 2000.
Late comeback
The Blue Jays had looked poised to win their first MLB championship since 1993 after taking an early 3-0 lead after Bo Bichette’s third inning three-run home run.
Toronto had led 4-2 heading into the eighth inning and were just six outs from victory.
But Dodgers third baseman Max Muncy crushed a home run to make it 4-3 and give the defending champions a flicker of hope.
Then Rojas punished a loose pitch in the top of the ninth to suddenly knot the score at 4-4.
Toronto then appeared set to seal a walkoff win in the bottom of the ninth inning when Yamamoto loaded the bases after taking over from reliever Blake Snell.
But Rojas’s superb throw cut down Isiah Kiner-Falefa as he attempted to cross home plate.
There was more drama to come when Ernie Clement’s high fly ball deep into left-centerfield saw Dodgers outfielders Kike Hernandez and Andy Pages collide as they went for the catch. Pages though came up with the ball and somehow the Dodgers had survived.
Toronto then flipped the script in the top of the 10th inning, escaping a bases-loaded situation of their own to leave the Blue Jays another chance to walk it off in the bottom of the inning.
Yamamoto, though, mowed through the Blue Jays in order to take it to the 11th inning.
After Rojas and Shohei Ohtani were quickly out, it fell to Smith to grab his moment of history.
The catcher demolished a loose pitch from Blue Jays reliever Shane Bieber 366 feet into left field to make it 5-4.
In the bottom of the inning, the Blue Jays had runners on first and third base with only one out. But Alejandro Kirk grounded into a double play to end the inning and the Dodgers had clinched a sensational win.
