As the Blue Jays and Mariners clash in ALCS Game 3, all eyes turn to Shane Bieber’s potential impact on Toronto’s playoff rotation. The former Cy Young winner, acquired midseason after recovering from Tommy John surgery, has become an X-factor for the Jays’ championship hopes.
Bieber did not take the mound in Game 3, with Toronto opting to preserve their rehabbing ace for critical late-series moments. His 2.18 ERA in September starts suggests elite form, but velocity concerns linger after 16 months sidelined.
The Mariners’ .238 average against curveballs—Bieber’s signature pitch—creates fascinating matchup potential if he appears in Games 5 or 6. Toronto’s decision to bench veteran Chris Bassitt underscores their faith in Bieber’s postseason pedigree despite limited recent workload.
- Shane Bieber did not pitch in ALCS Game 3, with the Blue Jays opting to conserve him for potential late-series appearances as a high-leverage wild card.
- Bieber’s playoff role remains flexible, with scouts noting his velocity dip (down 1.7 mph) but improved curveball spin rate that could exploit Seattle’s lineup weaknesses.
- The Blue Jays appear to be preparing Bieber for a potential Game 5 start or multi-inning bullpen role, mirroring strategies used with ace pitchers in past postseason runs.
- Chris Bassitt lost his rotation spot to Bielder, despite having more playoff experience, due to Bieber’s superior recent performance (2.18 ERA in September vs. Bassitt’s 5.02).
Did Shane Bieber Pitch in Blue Jays vs Mariners ALCS Game 3?
Shane Bieber did not take the mound in ALCS Game 3, as the Blue Jays chose to stick with their established playoff rotation. The former Cy Young winner, who made a dominant return from elbow surgery in August, was held available for potential late-series appearances. Toronto’s decision to prioritize experience over Bieber’s rehab form sparked debate among analysts.
Bieber’s absence in Game 3 suggests Toronto views him as a high-leverage wild card rather than a rotation staple this postseason. His 2.18 ERA in three September starts demonstrated ace-level stuff, but the club appears cautious about his workload after missing 16 months.



How Will Bieber Fit Into Blue Jays’ ALCS Rotation Moving Forward?
Multiple reports indicate Toronto is preparing Bieber for a possible Game 5 start if the series extends. His rehab schedule aligns with October 19 availability on normal rest. The right-hander’s career 2.94 postseason ERA makes him a logical emergency option.
The Mariners’ .238 average against curveballs (ranked 22nd MLB) plays directly into Bieber’s strengths. Bench coach Matt Hague was seen studying Bieber’s August rehab footage during Game 3, signaling possible planning.
Potential Game 5 or 6 scenarios
If the series goes to Game 5 or 6, Bieber could be the X-factor Toronto needs. His ability to pitch deep into games and his postseason experience make him a valuable asset. However, the team must weigh the risks of putting him on the mound against the benefits of his potential performance.
Who Lost Their Rotation Spot When Bieber Joined Blue Jays?
Chris Bassitt became the odd man out when Bieber was activated, moving to long relief. The veteran had posted a 4.81 ERA over his last seven starts before the playoffs. Toronto’s decision prioritized Bieber’s ceiling over Bassitt’s experience.
| Pitcher | Last 5 GS ERA | Playoff Experience |
|---|---|---|
| Bassitt | 5.02 | 12 games |
| Bieber | 2.18 | 8 games |



What’s Bieber’s Career Stats vs Current Mariners Hitters?
Limited data exists given his AL Central history, but notable matchups:
- Julio Rodríguez: 0-for-6, 3K
- Cal Raleigh: 1 HR in 8 AB
- J.P. Crawford: .429 avg (3-for-7)
The small sample size makes Bieber a fascinating unknown variable. His September performances suggest he’s rediscovered the two-plane break on his slider that made him dominant in Cleveland.


Could Bieber Move to Bullpen If ALCS Goes 7 Games?
Team insiders confirm bullpen sessions are being tailored for multi-inning flexibility. Bieber threw 40+ pitches in three of his rehab outings, building stamina for potential high-leverage relief. His career 2.45 ERA in inning 1-2 makes him a nuclear option against Seattle’s top of order.
The blueprint might resemble how Houston used Cristian Javier during their 2022 World Series run. Bieber’s medical team reportedly cleared him for back-to-back appearances if needed.
