Another talented Toronto Blue Jays reliever prospect is reportedly headed to Triple-A.

According to Sportsnet’s Shi Davidi, right-hander Nate Garkow is on his way to Buffalo to join the Bisons’ bullpen, which has lost multiple arms to major-league promotions in the last week-plus.

In that time, the Blue Jays have called up the likes of Canadian Adam Macko, Chase Lee and, most recently, Tanner Andrews, who was activated and added to the 40-man roster on Monday as the corresponding move to Dylan Cease’s IL placement.

Garkow was invited to Toronto’s big-league camp during spring training, as Davidi noted. Since then, he’s made 15 relief appearances with Double-A New Hampshire, pitching to a 3.63 ERA and 4.78 FIP across 17.1 innings, covering one save and hold each.

The 28-year-old reliever — Rule 5-eligible after the 2027 season — is widely regarded for his plus changeup, the primary source of his remarkable strikeout totals. He punched out over a third of the batters he faced over 53.2 combined innings split between High-A and Double-A last season. However, he’s struggled mightily to carry over that success into 2026.

There’s been a decline of nearly 15 per cent in Garkow’s year-to-year strikeout rate, while his walk rate has increased by 3.5 per cent this season.

On a more positive note, the 5-foot-11 hurler has upped his ground-ball rate to a career-high 43.2 per cent, ranking second among Fisher Cats relievers thus far. So if he can correct his command woes, that should help put him back on track as one of the organization’s most intriguing relief prospects.

Following last season’s stellar performance, Garkow — signed out of Indy ball in 2024 — entered this past spring on the fringes of top 30 prospect boards throughout the industry, but with the potential to force his name into that mix with another strong showing. Thus far, that hasn’t been the case.

But perhaps he can start to turn things around with this opportunity at Triple-A.
