Included in this year’s Major League Baseball postseason stint are some of Canada’s top professional players spread across the bracket. Unfortunately, some of these players’ postseason experience ended in the Wild Card round, where their club did not move on. Canada has produced some of the most relevant names in the game within the past few years. Teams have drafted players from the north, who have become a staple in the organization. Canadian players involved in this year’s October-fest, specifically in the Division Series between both leagues, include:
Vladimir Guerrero Jr, Toronto Blue Jays
Guerrero Jr faces a huge postseason appearance after inking a huge contract to remain in Toronto for the next 14 years earlier this season. The Montreal-born Blue Jay is a five-time All-Star and is looking to carry the Jays into a deep playoff run. His performance will be magnified, as the club expects big production in clutch scenarios, especially with Bo Bichette potentially on the sidelines. Josh Naylor, Seattle Mariners
Traded from the Diamondbacks to the Mariners this summer, Naylor plays a huge offensive role with Seattle. The Mississauga, Ontario native is a 20-home run, 92 RBIs contributor and will be key in the Mariners lineup. Naylor is nursing a groin injury but is expected to be back to play soon.
Matt Brash, Seattle Mariners
The right-handed reliever from Kingston, Ontario, will be a part of the Mariners’ bullpen in the 2025 postseason. The right-hander boasts a 2.47 ERA through 53 appearances this season, amassing an 11.0 K/9 with a 1.246 WHIP.
Michael Soroka, Chicago Cubs
Hailing from Calgary, Alberta, right-hander Michael Soroka found himself heading to the NL Central this summer and is now with the Cubs as they head to face the Milwaukee Brewers in the NLDS. He was added to the Cubs’ postseason roster for the Wild Card matchup against the Padres, appearing in Game #2 to finish out the contest (and eventual loss), tossing a clean 2/3 of an inning.
Jameson Taillon, Chicago Cubs
Hailing from Florida but holding dual citizenship thanks to his Canadian parents, Jameson Taillon played a huge role in the Cubs’ rotation this season, authoring a 3.68 ERA across 23 starts while missing some time due to injury. The Cubs turned to him for the pivotal Game #3 matchup against the Padres yesterday, and he shoved through four innings of work, allowing just two hits to the tune of zero runs while striking out four.
Jordan Romano, Philadelphia Phillies
Romano is still a big part of the Phillies’ bullpen, despite a rough start to the 2025 season. He was pulled from the closer role after massive struggles and was placed to work in short relief. He likely still cracks the postseason roster despite a late-season finger injury and a gaudy 8.23 ERA, but the Phillies and Canadian manager Rob Thomson could leave him off the NLDS roster given his recent return from injury.
Rob Zastryzny, Milwaukee Brewers
This huge 6-foot-3 left-hander is a staple in the reliever pool for the Brewers when healthy. The southpaw will also be short relief for Milwaukee and heads into the postseason with a 2.45 ERA and a 1.18 WHIP across 22 innings in the Brew Crew bullpen.
