A first-inning blitz and a dominant outing by rookie starting pitcher Trey Yesavage put the Toronto Blue Jays within one win of their first World Series title since 1993.

Major League Baseball's only Canadian franchise hammered the Los Angeles Dodgers 6-1 to give them a 3-2 lead in the best-of-seven 'Fall Classic', which now returns to Toronto for its conclusion.

Right-hander Yesavage, who was only called up to the majors in September, threw seven solid innings, with 12 strikeouts - a World Series record for a rookie - and only gave up one run.

The game started in unbelievable fashion at Dodger Stadium as Davis Schneider launched the very first pitch of the night over left field for a home run, and Vladimir Guerrero Jr repeated the feat off the second pitch he faced, leaving the Dodgers 2-0 down before some fans had taken their seats.

While Enrique Hernandez halved the deficit with a solo homer in the bottom of the third inning, Toronto restored their two-run lead straight away as Ernie Clement's sacrifice fly scored Daulton Varsho.

It got even worse for the Dodgers in the top of the seventh as multiple wild pitches and a walk allowed Addison Barger to score, and Bo Bichette drove in Andres Gimenez to make it 5-1.

Isiah Kiner-Falefa's base hit added another run in the eighth as the home fans headed for the exits, on a night when even the Dodgers' Japanese superstar Shohei Ohtani went hitless for the second successive game.

After a travel day, the series returns to Toronto on Friday for game six at the Rogers Centre, also the venue for a potential decider on Saturday.
