Blue Jays home run pick

Alejandro Kirk (+425 at BetMGM)

Alejandro Kirk may not look like a prototypical baseball player, but boy, can he hit.

The Mexico native played a massive part in Wednesday’s win, finishing 2-for-4 with a three-run home run. Kirk went deep 15 times in the season, and he’s already left the yard three times in the playoffs. 

Kirk has enjoyed himself in the past against Mariners starter Luis Castillo, who takes the ball this evening. He’s 4-for-8 with a homer and two RBI. 

Kirk is hot, and he could very well leave the ballpark once again in Game 4. 

Mariners home run pick

Eugenio Suarez (+700 at BetMGM)

Eugenio Suarez hasn’t swung it too well in the postseason, batting just .152 with one home run in 33 at-bats. However, he went deep 49 times in the regular season, and tonight’s matchup plays in his favor.

The Blue Jays send Max Scherzer to the hill, and Suarez has homered twice off him in 19 at-bats. 

The third baseman smacked 36 bombs off right-handed pitchers in 2025, and he tends to showcase his power even more at home, clubbing 30 round-trippers.

Suarez is always a power threat, and Scherzer has had issues with the HR this year, allowing 19 in 17 appearances.
