Down goes another one. 
The Toronto Blue Jays have lost another young arm to a season-ending injury as right-hander Jake Bloss is set to undergo UCL surgery on his right arm, the club announced Tuesday. It will officially mark a disappointing end to his 2025 campaign, putting him on the shelf until likely midway through &#8217;26.
While Bloss has thrown his final pitch of the &#8217;25 season, the team has yet to determine which type of procedure he&#8217;ll have, whether it&#8217;ll end up being full Tommy John surgery or require a brace to be inserted, or a hybrid of the two. The team also hasn&#8217;t revealed the timing of when he&#8217;ll go under the knife.

It&#8217;s a devastating blow for Bloss, who departed his sixth start with triple-A Buffalo due to injury on May 3, completing just 3.1 innings. He finishes with a 6.46 ERA and 4.74 FIP over those six outings, issuing 24 strikeouts and 13 walks in 23.2 innings.
The 23-year-old starter &#8212; acquired by Toronto as part of the package from Houston in last year&#8217;s Yusei Kikuchi trade &#8212; endured a rough start to his season with the Bisons, pitching to an inflated 10.32 ERA and 8.06 FIP over his first three starts. But he had rattled off two consecutive bounce-back performances entering what would be his final start of &#8217;25, punching out 12 across nine innings of two-run ball &#8212; with both runs unearned.
Bloss, a third-round selection in 2023, made eight starts with the Bisons after arriving via trade. He climbed four different levels last season, including the major leagues, where he made a trio of starts for the Astros amidst the team&#8217;s rash of starting pitching injuries.
That&#8217;s something the Blue Jays organization can relate to, at least on the minor-league front, after several prospects underwent major surgeries a season ago, including Ricky Tiedemann, Chad Dallas, Brandon Barriera, Landen Maroudis, Nolan Perry, T.J. Brock and Connor Cooke. Alek Manoah also missed most of the &#8217;24 season due to UCL surgery that inserted a brace in his right arm.
Bloss now becomes the latest name to join that list, eliminating him as a potential option to pitch for the Blue Jays this season amidst continued uncertainty involving their fifth starter&#8217;s spot.
