TORONTO -- Eventually, the Blue Jays’ record book will just be Vladimir Guerrero Jr.'s name with a few others sprinkled around it.
If Guerrero continues on this pace for even the majority of his 14-year extension, so many of the all-time marks will belong to him, from hits to home runs to games played and beyond. Some of the single-season marks still stand tall, though, and when we turn to the Blue Jays’ all-time pitching records, some feel like they’ll last forever.
Flipping through the record book, here are 10 that future Blue Jays players could be chasing for a long, long time.
1. Dave Stieb’s … everything
Stieb wasn’t just great, he was an absolute workhorse, a pitcher with the pure “stuff” you’d see in today’s game, but with the ability to throw … and throw … and throw.
Keep in mind that just three pitchers in Major League Baseball threw 200-plus innings in 2025, and no pitcher had even three complete games. Then, consider these club records from Stieb:
- 2,873 career innings pitched (career)
- 103 complete games (career)
- 288 1/3 IP in 1982
- 19 complete games in 1982
There will never be another Dave Stieb in Toronto. They don’t make Stiebs any more.
2. Roy Halladay’s 22-win season in 2003
Only six pitchers have won 20 games in Toronto: Halladay (22 wins in 2003; 20 in '08), Jack Morris (21 in 1992), Roger Clemens (21 in '97; 20 in '98), Pat Hentgen (20 in '96), David Wells (20 in 2000) and J.A. Happ (20 in '16). Remember, too, that Halladay won 22 games in a season in which he made 36 starts, a number you won’t see happen again. Perhaps another 20-game winner sneaks up to surprise us, but can you really see a Blue Jays pitcher winning 23 games?
3. The Rocket’s 292 strikeouts
Clemens set a high bar with 292 K's in 1997, and the next season, he claimed second place in Blue Jays history with 271. Robbie Ray tried in 2021 (248 K's) and Kevin Gausman took a run in '23 (237), but Clemens’ combination of workload and strikeout ability makes this such a difficult record to touch. Even though Clemens’ two seasons are rarely memorialized in Toronto, we may never see better pitching in this city.
4. Jose Bautista’s 54 home runs in 2010
Back in 2021, when Vladimir Guerrero Jr. hit 48 homers, it felt like this record would fall in just a matter of time. Since then, though, we’ve learned that Guerrero is likelier to land in the range of 30-40 home runs, which works just fine within his overall offensive game. Guerrero still has every bit of talent to launch 55 in a season if it all comes together, but Bautista could sit comfortably with this record for years to come.
5. Carlos Delgado’s .949 career OPS
Guerrero will eventually knock off Delgado in many counting-stat categories, but this one frames just how dominant Delgado’s time was with the Blue Jays. He owns the highest career slugging percentage in Toronto (.556) and is second with a .392 OBP, trailing only John Olerud (.395). Good luck catching that one, future Blue Jays.
OPS captures Delgado well because it speaks to not just his peaks, but his greatness across his entire time with the organization. Perhaps a superstar can come in and rip off a few elite seasons, but to do this over a decade? That’s a tall ask.
6. Mark Eichhorn’s rubber arm
While Eichhorn’s 1986 season may be one of the most interesting in Blue Jays history, with a 1.72 ERA over 157 innings of relief, his record of 89 appearances the following year feels like it may never be touched. Now that pitchers must face a minimum of three batters, which eliminates the old-school lefty specialists, even 65 appearances feels like a lot. Could you imagine a modern reliever running in for their 90th?
7. Duane Ward’s 45 saves
First part of a tandem with Tom Henke, then taking over as closer himself, Ward’s 1993 season was dominant with 45 saves and a 2.13 ERA. You could drop him onto a roster in 2026 and he’d fit right into the modern game. No other closer has touched 40 in club history, though, and Ward is now into his fourth decade owning the record.
8. Dave Collins’ 60 steals
Lloyd Moseby’s career club record of 255 feels awfully safe, too, but Collins’ 60 steals in 1984 feels even further out of reach. Collins played just two seasons with the Blue Jays, but it’s been decades since anyone came close to this. Roberto Alomar ranks second with 55 in 1993.
9. John Olerud’s 1993 season
Olerud hit .400 into the first week of August that season and finished the year with single-season club records in average (.363) and on-base percentage (.473). Olerud was one of the most gifted hitters this organization will ever see, and if these records ever fall, someone will be taking home an MVP award.
10. Tony Fernandez working overtime
Due to a game that was rained out, ruled a tie and then replayed the next day, the Blue Jays played 163 games in 1986. They finished with an 86-76-1 record, and since Fernandez was the only player on the roster to play in every single game, he owns a 163-game season -- played entirely with one club. Good luck with that one!
