It would’ve been nice if Jake Bloss stayed healthy this past season.
With the Toronto Blue Jays’ rotation in shambles all season long, Bloss would have easily gotten a look in the rotation down the stretch. Not only would this have helped the Jays, but it would have let them see what they have in Bloss moving forward.
Instead, Bloss remains a prospect, ranking as our 18th-best Blue Jays prospect in the end-of-season countdown. If you missed who ranked 19th, you can read about Dub Gleed here.

Jake Bloss

Position: Starting pitcher
Throws: Right
Born: June 23rd, 2001
Acquired: Trade with Houston Astros
Previous ranking: 18th
Bloss was drafted in the third-round of the 2023 MLB Draft by the Houston Astros. After appearing in seven games to end the 2023 season, Bloss began his first full professional season with their High-A team. The right-handed pitcher made four starts there, then eight starts with their Double-A team, before one more at the Triple-A level.
With the Astros’ rotation decimated, Bloss joined the team less than a year after being drafted. In three starts, Bloss had a 6.94 ERA and 76.2 FIP in 11.2 innings of work. Ahead of the 2024 trade deadline, Bloss, Will Wagner, and Joey Loperfido were sent to the Blue Jays in exchange for Yusei Kikuchi.
Bloss didn’t have a great start to his Blue Jays tenure, authoring a 6.91 ERA and 5.87 FIP in 27.1 innings of work over eight starts. Making six starts to begin the 2025 season, Bloss posted a 6.46 ERA and 4.76 FIP in 23.2 innings pitched. In May, he went under the knife for the brace version of Tommy John surgery, meaning he missed the rest of the 2025 season.
Because of the injury, Bloss didn’t make his 2026 season debut until May 12th. Over the next two months, he made 11 starts across four levels, finishing with a 6.18 ERA and 6.01 FIP in 39.1 innings of work. Nearly half of those starts came with the Triple-A Buffalo Bisons, where he had an 8.69 ERA and 7.66 FIP. In July, he was shut down for the season due to a shoulder injury, though he is set to pitch in the Arizona Fall League.
There’s still a good prospect in Bloss, featuring a fastball that sits in the mid-90s but reaches as high as 98 mph when healthy. His best secondary pitch is a curveball, while his slider grades out as average, his cutter as fringe, and changeup as below-average. He has average command.
Bloss is an MLB-ready prospect, but the priority for the 25-year-old is to stay healthy. If he can do that, he should be in their plans for next season, especially considering he’s out of options next season.
