Can the Blue Jays Reach the Playoffs While Relying on Bullpen Days?

The Toronto Blue Jays have posted a 9-7 record in games classified as bullpen days, a surprisingly strong mark for a club that has been forced to improvise. The approach has helped keep the Jays in the playoff race, but whether it remains a viable path to the postseason is another question entirely.

Even with one of the better relieving corps in baseball, the Jays just don’t have the offensive firepower to hold off teams like the Guardians. Spencer Miles and Ricky Tiedemann were strong on Tuesday, but as the offense failed to add on runs, the Jays were forced to keep Spencer Arrighetti and Joe Mantiply in the game for a handful of extra batters.

Bullpen games for the Jays can feel like throw-away games, and that isn’t ideal during this final stretch. They can almost feel like the Jays aren’t putting forth their best effort because they are more focused on resting leverage arms for winnable games.

The fact that the team is above .500 in bullpen days has helped them remain competitive in the fight for the final Wild Card spot. Whether the team can maintain that success if the timelines for Shane Bieber and Trey Yesavage remain uncertain is another story. It was bad timing for the Jays, as they scheduled their bullpen day this week against Gavin Williams, who threw a gem.

The challenge for Toronto is that bullpen days require a deep bullpen, an offense capable of creating runs, and careful workload management. Jays starters have been particularly strong the past few weeks, but to expect six or seven innings every time out, especially against teams also vying for the postseason, is a lot to ask.

Without extended outings from starters like Dylan Cease and José Soriano (not to mention Max Scherzer), the likes of Tyler Rogers, Braydon Fisher, Mason Fluharty and Louis Varland will need to continue to work close to their capacity.

Patrick Corbin was signed by the Jays to be an insurance policy for the starting rotation. His 3-4 record over 19 appearances, including 15 starts, was adequate but not outstanding. With an ERA of 5.51 over that span, he helped the team tread water.

Comparing his record with the bullpen day record, you can see why the team hasn’t looked to replace him altogether and instead went to starting by committee.

The strongest argument against keeping bullpen days is the strain on the relievers. Toronto's bullpen has been among the busiest groups in baseball, logging more than 550 innings. As innings pile up, even for non-leverage arms, fatigue is a real concern.

The key concern for Toronto is whether the bullpen can maintain its effectiveness under such a heavy workload through the season's final month.

The Jays bullpen must be getting close to a breaking point where precision, not to mention velocity, may start to dive. At the same time, the importance of every series is starting to grow, so taking a chance on a bullpen day instead of a bona fide starter is a risk.

When the season began, it seemed like the Jays would have an abundance of starters, but injuries have taken their toll. Instead, manager John Schneider has had to be creative.

With fewer than 30 games left, management has yet another tough decision to make. Can they afford to drop the bullpen days and go with a three- or four-man rotation? The team has three days off in the next three weeks.

Are Arrighetti and Jameson Taillon the short-term solution until Bieber and Yesavage come back? The Jays are clearly a bit hesitant to have Arrighetti go two times through an order, perhaps based on reduced velocity and pitch execution. Taillon is expected to return from the injured list and start on Friday.

If the Jays can grab a spot in the postseason, they also need to ensure they haven’t depleted their starting rotation or bullpen. While many teams might fear the Jays in a short series, Toronto still needs to rest their arms whenever they can.

In order to make the postseason, the Jays don’t need to be perfect, but they do need to outperform their direct competitors. There will be no tapering for this team as every game and every series matters.

Taking Cease out of a blowout an inning or two early seems like the right move, but when Fisher throws nearly 30 pitches, that logic falters. Fisher probably isn’t available for a day or two after.

John Schneider has been using his bullpen all season as if it was October. He has developed a mini-roster of leverage arms he trusts and has stuck to that strategy since Opening Day.

Take, for instance, that in the last 32 games, Jays starting pitching has an ERA of 2.77, while their top six relievers, namely Varland, Rogers, Miles, Fisher, Fluharty and Sewald, have a collective ERA of 1.23. Unsurprisingly, the team has a record of 20-12 during that stretch.

In that stretch of games, there have been a handful of bullpen days. Those games have helped the club stay afloat, but they work best as a complement to a stable rotation rather than a long-term solution.

Good starting pitching preserves bullpen health, provides predictability, and reduces roster strain. The Jays would undoubtedly welcome additional rotation stability if it became available. The reality, however, is that contenders must often function with imperfect personnel. Adaptability becomes a competitive skill.

The Jays have needed to exemplify adaptability throughout the season. The club has cycled through pitchers, adjusted roles repeatedly, along with running a continuous caravan between Buffalo and Toronto. With 36 different pitchers appearing for the team in 2026, there is a sense there might be more to come. The resiliency of the pitching and the coaching staff has so far paid dividends.  

Wear and tear is the variable that is most concerning this late in the season. The margin for error shrinks as the season progresses.

With the return of Yesavage and Bieber on the horizon, the Jays just need those reinforcements to arrive before the strain on the bullpen becomes too great. The occasional bullpen day can be effective, but Toronto's path to October is far safer with starting pitching taking the lead.
