Blue Jays Welcome Back Shane Bieber, But Back-To-Back-To-Back Bombs Spoil Return

It’s not often that a team gets to add a former Cy Young winner to its rotation in the middle of June, but that’s exactly what the Blue Jays did on Tuesday afternoon when Shane Bieber made his season debut.

Bieber’s return puts the Jays’ starting rotation as close to full strength as it's been since Cody Ponce blew out his ACL in the third inning of his own Blue Jays debut all the way back in March, but the best version of this rotation includes a much better version of Bieber than we saw in this start.

Across 3.2 innings against the Astros, Bieber threw 75 pitches, allowing four runs on nine hits, including three consecutive solo homers in the fourth, and a total of 10 hard-hit balls.

The important thing is that Bieber was actually able to get on a Major League mound and make a start. The Blue Jays will be more concerned with how he recovers from this than with the results, but the expectations for his performance going forward have to be much higher than what he showed here.

The Jays will also be concerned with the underlying numbers, because they matched the poor results.

Bieber’s fastball averaged 91.7 MPH, down almost a full mile compared to the 92.6 he got out of it in 2025. Bieber also forced only six whiffs, none of which were on his fastball. A ratio of 10 hard hit balls to six swings and misses is not a very sustainable practice.

There’s no positives to find in his velo being down, but in all fairness, Bieber’s never been a stuff guy – he hasn’t averaged 93 MPH on his fastball since 2020. Instead, his ability to mix and locate five different pitches has helped him put up many impressive statistical seasons with Cleveland over the years.

From 2019 through two starts in 2024 before undergoing UCL surgery, Bieber threw 728.1 innings and allowed just a 3.02 ERA for the Guardians. It’s what the Jays hoped they were acquiring when they traded for him at the 2025 trade deadline, and for the most part, it’s what they got down the stretch and deep into the playoffs. Bieber followed up a 3.57 ERA across 40.1 regular-season innings after the trade deadline with 18.2 innings and a 3.86 ERA through game seven of the World Series. 

After Bieber opted into his player option for just $12M at the beginning of the offseason, concerns were raised about some persisting health issues from that 2024 elbow surgery. Those concerns were vindicated when Bieber’s spring training build-up was delayed with forearm fatigue and elbow inflammation cited as he started the season on the injured list.

His rehab process was extensive as well. Bieber made five starts between three minor league levels on his way back to the big leagues, and while the results don’t mean much of anything, he did get hit hard in those as well. Across 17 innings, he had a 6.88 ERA and struck out just 14. His velocity was also reported to be down in many of those.

It’s not unusual to see established major leaguers struggle in minor league rehab outings and then turn it on once they get back to the big leagues, but that’s not what we saw in Bieber’s start against the Astros.

Is it time to press the panic button on Bieber? Absolutely not.

Regardless of the team’s need for dependable starting pitching, Bieber has shown he can be effective without elite-elite stuff as recently as October, and with some more effective pitch mixing and location, we’re sure to see him get back to being a reliable option every fifth day.

The current shape of the rotation also gives Bieber essentially unlimited runway.

Bieber came in to fill a slot that had been a bullpen day since Max Scherzer went back on the IL in early June, and if we’re honest, it was often a bullpen day even when Scherzer was making the starts. Even then, if you consider Dylan Cease, Kevin Gausman, and Trey Yesavage ahead of him on the depth chart, the Jays have been running out Scherzer and Patrick Corbin to various degrees of ineffectiveness for the better part of this season.

Obviously, if Bieber can get back to anything close to his Cy Young form, he raises the Blue Jays’ ceiling drastically, but even if he ends up in some sort of five-and-dive routine, he’ll have raised the floor of the pitching staff.

The Jays have thrown the fourth most innings out of the bullpen in 2026, and Bieber’s ability to provide some length should help the Jays find more days off for Louis Varland, Jeff Hoffman, Tyler Rogers, and Mason Fluharty, who are all top 12 in reliever appearances.

Unfortunately, we didn’t see the ceiling or floor-raising version of Shane Bieber in that first outing on Tuesday afternoon, but if he can continue to shake off some rust going forward, he absolutely transforms the starting rotation.
