The White Sox went looking for bullpen help at the deadline and traded for Huscar Brazobán, but the arm making the biggest difference down the stretch was already in the building.
Rookie Hagen Smith has turned into one of Will Venable’s most trusted high-leverage relievers almost as soon as he arrived. Since his MLB debut on Aug.
9, Smith has worked 23.2 innings and given up just three earned runs, good for a 1.14 ERA. He has piled up 34 strikeouts against 12 walks in that span.
The walks remain the one obvious concern. That was the issue that followed Smith through the minors, and his 13.2% walk rate still shows it.
Even so, the rest of the profile has been overpowering enough to cover it up. He has attacked hitters with elite swing-and-miss stuff and simply made it hard for them to make solid contact.
If the innings were high enough to qualify, Smith’s 37.4% strikeout rate would sit among the best in the majors. That number isn’t just a fluke of a tiny sample, either. Hitters have struggled to get anything going against him in a White Sox uniform, as shown by his 37.7% whiff rate, 2.2% barrel rate and .173 expected batting average.
Smith has mostly built his outings around a fastball-slider mix, but he has also mixed in a cutter and a changeup to keep hitters guessing. The changeup has been a small part of the plan - just 3% usage - yet it has produced a 40% whiff rate, second on the staff among his four pitches behind only the slider at 45%.
That changeup could become even more important if he keeps sharpening it over the offseason. The rest of the arsenal already looks nasty enough.
It was on full display last Saturday in St. Louis. With the game tied 4-4, Venable turned to Smith in the fifth inning, and the rookie answered with a perfect 1-2-3 frame against the middle of the Cardinals’ order.
He started the sixth by freezing Thomas Saggese with an 83 mph slider in the dirt, then got Masyn Winn to swing through an 86 mph changeup for back-to-back strikeouts. By the time Grant Taylor replaced him in the seventh, Smith had thrown just 21 pitches, completed two perfect innings and struck out three.
He kept rolling after that, following the St. Louis outing with two more scoreless innings against the Cleveland Guardians. In that appearance, he gave up one hit, issued no walks and struck out three.
The run of dominance was interrupted Wednesday when Cleveland finally pushed across two runs against him over 1.2 innings. Even then, the damage came more from Smith’s control than from hard contact. He walked a pair of hitters instead of getting squared up.
The second walk came with Smith one out from escaping the inning. After he issued a free pass to Austin Hedges, Venable pulled him, and both runners Smith left behind later scored when Sean Newcomb allowed a two-run homer to Petey Halpin.
For a bullpen that needed a lift at the deadline, Smith has become the surprise answer: a young power arm looking every bit like the kind of pitching piece Chicago hoped it was getting when it took him in the first round of the 2024 MLB Draft.

White Sox May Have A Sean Burke Decision Taking Shape
The White Sox have spent much of their extension energy looking elsewhere for now, but the conversation around young pitching is starting to get more interesting. Washingtons reported push to lock up Cade Cavalli, coming on the heels of his strong 2026 season, offers a useful comparison point for Chicago as it weighs how to handle Sean Burke, whose own performance this year has put him in the same general conversation.
Chicago does not appear to be at the decision stage yet, and the clubs current extension focus remains on other players. Still, Burkes emergence gives the White Sox something to consider for the road ahead, especially if they decide the next wave of planning should center on their young arms rather than only the position-player side of the roster.

Former White Sox Infielder Just Hit Another Rough Turn
Lenyn Sosas path has taken another sharp turn, with the Toronto Blue Jays releasing the infielder after his stint with Triple-A Buffalo. Sosa had landed in the Toronto system after being outrighted in mid-August, following the trade that sent him over from the White Sox, and he was trying to carve out a role in the organization down the stretch.
For Chicago fans who watched him come through the system, it has been a difficult season to track. Sosa was slowed by injuries and never found much rhythm offensively in 2025, leaving him in a precarious spot before Toronto moved on. His latest release adds another layer of uncertainty to a career that once looked like it might still have a clear path forward. [Read more 🡒]
White Sox Win Turned On One Tense Moment And A Huge Vargas Night
The White Sox found themselves in the kind of tight, late-inning spot where one call can shape the whole night, and Will Venables successful challenge made sure a tying run never crossed for Detroit. It was the sort of moment that can get lost in the box score but tends to loom large in a game like this, especially with Sean Burke giving Chicago six solid innings and allowing just one run to keep the club in control.
Miguel Vargas made sure the bigger story stayed on the Chicago side of the ledger. His home run capped a night that kept stacking milestones, including a team first that speaks to just how complete his season has become. For a White Sox club looking for any sign of momentum, it was the rare game where the pitching held the line and one bat did enough damage to make the rest matter less. [Read more 🡒]
