Nolan Perry leads a trio of Blue Jays prospects who could make their MLB debuts in 2027. Javen Coleman and Jay Harry are right behind him.

Injuries opened doors all over the roster in 2026. Cody Ponce made one appearance, Addison Barger missed most of the year and Anthony Santander was limited again.

That led to a long list of debuts, from Brett Bateman and Sean Keys to Ricky Tiedemann and Charles McAdoo. Next year could bring more.

Perry is first in line. After missing all of 2025, he climbed from Single-A Dunedin to Double-A New Hampshire, where he made nine starts.

His full line was dominant. He posted a 2.50 ERA across 82.2 innings with 117 strikeouts.

He struck out 12.7 batters per nine while allowing just 5.7 hits per nine. He's the organization's No. 2 prospect and top pitcher.

Javen Coleman gives the Blue Jays a lefty bullpen option

Coleman made his name this spring. With players away at the World Baseball Classic, he threw 6.2 scoreless innings over six games, striking out six.

Injuries slowed him during the season. He allowed 12 earned runs in 11.1 Triple-A innings late in the year, though an injury may have played a role.

Why does he matter? Because Toronto's bullpen badly needs another lefty behind Mason Fluharty.

Harry is the bat to watch. He finished 2026 in Buffalo after slashing .298/.343/.495 over 105 games.

He set career highs with 28 doubles and 14 home runs while driving in 76 runs. He can play short, second and all three outfield spots.

Harry is the one most likely to make an impact. A versatile bat with that kind of production fits a roster still searching for answers at second base and in the outfield.

These three are like the seeds you planted last spring. Most of them are sprouting, and next summer you find out which ones bloom.

A lockout could complicate everything. If spring training starts on time, though, all three will be pushing hard for their shot.

Perry and Harry still need 40-man protection before the Rule 5 deadline. Ross Atkins' decisions there will hint at just how close Toronto thinks they are.
