The 2025 Chicago White Sox season wasnât defined by wins. It was defined by arrivals.

A wave of young talent finally started breaking through â names like Colson Montgomery, Kyle Teel, and Shane Smith grabbing headlines and giving the fanbase something it hasnât had in a while: a reason to watch closely, even when the standings didnât cooperate.
But one of the most important developments of the year wasnât the loudest.
It was Grant Taylor â and it happened fast.
The White Sox brought Taylor straight to the big leagues from Double-A Birmingham in June, and within minutes, it was obvious he wasnât just another arm filling innings.
He looked like something else entirely: a pitcher with the kind of velocity and movement that makes hitters uncomfortable before the ball even leaves his hand.
This week, White Sox general manager Chris Getz didnât just praise Taylor â he placed him in a category that changes expectations overnight.

âGrant Taylor, I believe, has a chance to be an elite pitcher in this game,â Getz said while appearing on the Rekap White Sox podcast.
âAt this point, heâs a reliever for us. What does that mean in the future? Does he become a starter? Perhaps. Time will tell. But in the meantime, heâs in the bullpen. I think he can be in the Mason Miller mold. I do. I think this guy â heâs got elite stuff.â
The Mason Miller mold.
Thatâs not a casual comparison. Thatâs not something you throw out just to fill airtime.
Thatâs the kind of statement that either becomes a prophecy⌠or a pressure cooker.
Because Mason Miller isnât âgood.â Heâs not âpromising.â Heâs the blueprint for what baseball looks like when a reliever becomes a nightmare â a late-inning weapon so dominant he changes the entire shape of a game.
And the wild part is: Taylorâs raw ingredients actually support the idea.
If you only look at Taylorâs traditional stats, you might shrug. A 4.91 ERA doesnât scream âfuture elite closer.â It screams âneeds work.â It screams âinconsistent.â It screams âanother guy with a big arm who hasnât figured it out.â
But thatâs the trap with pitchers like Taylor.
Because the deeper you look, the more the story flips.
Taylorâs average fastball velocity sat at 98.7 MPH â a number that ranked in the 97th percentile in all of baseball. He generated swings and misses at an elite rate.
Even when he gave up hard contact, much of it stayed on the ground, supported by a strong 51.1% ground-ball rate.
And the underlying metrics paint an even sharper picture: an xERA of 2.91 and a FIP of 1.42 suggest Taylor wasnât getting exposed â he was getting unlucky. Let down by defense.
Punished by sequencing. Hit with the kind of âbad breaksâ that make a young pitcherâs stat line look worse than the actual performance.

His MLB debut felt like a trailer for whatâs possible. Three up, three down. Twelve pitches, ten strikes. First pitch at 101.5 MPH. Six fastballs over 100.
That isnât normal. Thatâs a warning label.
The comparison to Mason Miller is bold, but it also makes sense when you understand Millerâs own path. Drafted by the Athletics as a starter, Miller debuted as a starter in 2023 before injury pushed him into the bullpen.
By 2024, he wasnât just closing games â he was erasing them. He struck out 104 hitters, held opponents to a .160 batting average, then somehow got even better in 2025, allowing a .139 average against.
Miller became so valuable that the Aâs traded him to the Padres at the deadline in a deal that included shortstop Leo De Vries, a consensus top-five prospect in baseball.
Thatâs what âMason Miller moldâ really means.
It means franchise-altering leverage.

And now the White Sox are openly suggesting Grant Taylor could be that kind of weapon.
But hereâs the twist nobody can ignore: Taylor might be more than a reliever.
He started in college. He has the stuff to be stretched into a starter. And in a system that doesnât exactly overflow with ace-level upside, the idea of keeping him in the bullpen forever feels⌠safe.
Too safe.
Of course, there are concerns. Injury history matters. Workload matters. And the White Sox may decide the smarter route is maximizing his impact in shorter bursts, where the velocity plays even louder and the risk feels lower.
If his floor is âgood late-inning reliever,â thatâs already valuable.

But if his ceiling is âMason Miller-level terror,â then the White Sox might have stumbled into the rarest kind of rebuild asset: one that can flip games, flip seasons, and flip the way the league looks at them.
With additions like Seranthony Dominguez and the emergence of Jordan Leasure and Mike Vasil, Taylor wonât have to carry the bullpen alone in 2026.
And that matters, because the White Sox lost the most one-run games in baseball last season â the exact kind of pain that elite relief pitching can erase.
Now it comes down to one question that feels heavier the longer you sit with it:
Was Getz just hyping up his guy⌠or did the White Sox quietly find the one arm that can change everything? âĄ
