Toronto Blue Jays starting pitching prospect Jake Bloss continues to perform well in the Arizona Fall League, striking out six over just 2.2 innings on Tuesday night.

Representing the Mesa Solar Sox, he now has a 2.70 ERA through three starts, spanning 6.2 innings. His numbers were noted from the AFL account on social media.

This is an important fall for Bloss, as we dig deeper into his profile.

Ranked now as the No. 11 prospect in the Blue Jays organization by MLB Pipeline, Bloss was selected in the third round of the 2023 MLB Draft by the Houston Astros out of Georgetown. 

He actually made his major league debut in 2024 with the Astros, going 0-1 with a 6.94 ERA in three starts before getting traded to the Blue Jays in the deal that sent Yusei Kikuchi to Houston.

Bloss has had a hard time in the Blue Jays organization: He went 0-4 with a 6.91 ERA in eight starts at Triple-A Buffalo after the trade, and then he went 0-5 with a 6.46 ERA in 2025 before going down with Tommy John surgery.

He returned in 2026 to go 0-4 with a 6.18 ERA at four separate levels on the rehab trail. All told, he's 0-14 since getting to Toronto.

This fall is important for him to re-establish his prospect viability, to increase his chances of contributing to the Jays in 2027, and for getting some confidence in his health and ability again.

At the moment? He's got a good chance of contributing, but it doesn't feel likely out of the chute.

While the 2027 season is up in the air as a result of labor unrest and the Collective Bargaining Agreement, the Blue Jays do figure to have four starting pitchers already set: Dylan Cease, Jose Soriano, Trey Yesavage and Cody Ponce.

The No. 5 spot is up for grabs, but Bloss, Ricky Tiedemann, Nolan Perry, Jose Berrios and Bowden Francis will all have a chance at it at some point next season. And Spencer Miles is there also after performing admirably in multiple roles in 2026.

Bloss will likely be an innings limit as he works back, but he will still have the ability to contribute. His highest career innings total is just 93.1 (2024). He pitched just 39.1 in this regular season in the minors.
