Every former Blue Jay that could have an impact on Toronto’s path to the World Series

OF Rob Refsnyder, Boston Red Sox

Rob Refsnyder's time with the Blue Jays wasn’t a memorable one, coming over from a trade with the Yankees in 2017 at the deadline. After all, Refsnyder only managed to record a .196 average, .496 OPS, along with five runs scored, zero home runs and zero RBIs in 32 games down the stretch.

However, the 34-year-old outfielder has evolved into a valuable bench piece in recent years with the Red Sox. In 2025, Refsnyder has compiled a tidy .269 average, .838 OPS, together with 29 runs scored, nine home runs and 30 RBIs in 70 games played for Boston.

He didn’t do much damage during his time with the Jays, but Toronto must be wary the potential damage he could do now as a member of the Red Sox.

C Danny Jansen, Milwaukee Brewers

As a former Jays fan favourite, Toronto may have been glad that Danny Jansen was no longer in the same division to exact some revenge on his former team. But if the Jays potentially meet the Milwaukee Brewers in the World Series, they won’t be able to avoid him any longer.

After struggling earlier in the season with the Rays, Jansen has settled in nicely as the Brewers’ backup catcher by amassing a .254 average, .779 OPS, along with 17 runs scored, three home runs and seven RBIs in 25 games played down the stretch.

More importantly, since leaving Toronto, Jansen has already had some success against his former team, albeit in a small sample size, as he has posted a .313 average, .771 OPS, together with a home run and two RBIs in nine games.

P Tim Mayza, Philadelphia Phillies

It wasn’t too long ago when Tim Mayza was one of the top relievers for the Jays, or in fact the entire league back in 2023. With a 1.52 ERA, along with 53 strikeouts in 53 1/3 innings as a lefty specialist for Toronto that season, he figured to be a mainstay in their bullpen for years to come.

However, a disastrous 2024 campaign with the Jays has led Mayza to join three other organizations in a span of two years, including stops in New York, Pittsburgh, and now the Philadelphia Phillies. With a less-than-stellar 4.91 ERA and 1.64 WHIP in eight relief outings with Philadelphia since being claimed off waivers from Pittsburgh at the end of August, Mayza might not factor into the Phillies’ postseason plans.

But if he does get the chance, the motivation he would get facing his former team in a potential World Series rematch between Toronto and Philadelphia could make him a dangerous arm coming out of the bullpen for the Phillies.
