AL Wild Card Series, Game 1 | Chicago White Sox (84-78, No. 6 seed) at Houston Astros (81-81, No. 3 seed, AL West champions) | Tuesday, September 29, 2026 | 5:00 PM ET / 4:00 PM CT | Daikin Park, Houston | NBC/Peacock/NBCSN
I have to be honest with you: three years ago I would have laughed if you told me I’d be writing a White Sox playoff preview in September. After 102 losses in 2025 and 121 losses in 2024, this team was a punchline. Tonight, they’re in Houston opening a best-of-three Wild Card Series as the first club in MLB history to reach the postseason immediately after back-to-back 100-loss seasons. As a Sox fan, I don’t care how they got here. I just care that they’re here — and that the last time this franchise saw October, it was this same Astros team that ended it in four games in the 2021 ALDS.
Let’s get into what actually matters tonight: the bullpen chess match, the injury situations on both sides, and why I think this series opens up in a way the moneyline doesn’t fully capture.

Two Bullpen Games, Zero Traditional Aces
This is the single biggest storyline of the night, and it flattens the gap between these two rosters more than people realize. Both managers are opening with a reliever-turned-starter instead of a traditional ace.
Will Venable is going with rookie left-hander Hagen Smith to open the game for Chicago. Smith has been outstanding in a limited role down the stretch — a 1.29 ERA with 41 strikeouts — but he’s never been stretched into a true playoff-length outing, and the expectation is he gives the Sox two, maybe three clean innings before the bullpen takes over.
Houston is countering with AJ Blubaugh (5-5, 3.66 ERA) in the same role, holding both Framber Valdez and Hunter Brown back for Games 2 and 3 rather than using either on short rest in the opener. Brown was Houston’s best starter all year (3.19 ERA, 124 strikeouts), and the fact that Joe Espada is willing to skip him in a win-or-go-home Game 1 tells you exactly how much value this Astros front office places on setting up their rotation for the full series. It’s a defensible move, but it also means Houston isn’t throwing its best arm tonight — and neither is Chicago. That’s a real equalizer.
For a White Sox team that’s outscored people all September on the strength of contact and patience rather than swing-and-miss stuff, a bullpen game against a bullpen game is about as fair a fight as this roster is going to get in October.
The Lineups: Where Chicago Can Actually Win This
Houston is the more talented team, full stop, and I’m not going to pretend otherwise. Yordan Alvarez had a season for the ages — he led all of MLB in batting average (.316), on-base percentage (.432), slugging (.601), walks (109) and OPS (1.033). Jeremy Peña chipped in 22 home runs at short. If either of them beats Smith or the Sox bullpen with a mistake pitch, this game can get away from Chicago fast.
But this White Sox lineup isn’t the punchline team from the last two seasons. Third baseman Miguel Vargas quietly had a monster year — 33 homers, 22 stolen bases, 101 walks, top-10 in the league in the latter category — and he’s the one hitter in this lineup capable of a series-altering swing against a shaky Houston bullpen behind Josh Hader. Second baseman Chase Meidroth posted a 4.5-WAR season that got buried under the noise of a last-place-turned-playoff-team storyline, and rookie first baseman Munetaka Murakami has provided more thump than Houston’s Christian Walker for most of the second half.
The one lineup spot that worries me as a fan: shortstop Colson Montgomery set an ignominious MLB record with 227 strikeouts this season. Against a Houston bullpen that will be looking to bury this game with soft stuff away once Blubaugh exits, Montgomery’s ability to shorten up and simply put the ball in play late in games could be the swing factor in a one-run affair.
Injuries That Actually Matter Tonight
Catcher Kyle Teel played in just 39 games this season for Chicago because of a hamstring strain and a high ankle sprain, and his absence behind the plate has quietly cost this pitching staff some of its game-calling continuity down the stretch — worth watching if Chicago’s bullpen game starts leaking runs in the middle innings.
On Houston’s side, outfielder Daulton Varsho is likely done for the year with cysts in his left wrist, which has pushed the Astros into a slightly thinner, less athletic outfield mix than the one that carried them for most of the summer. It’s not a fatal blow, but it’s one fewer above-average defender and left-handed bat in an Astros lineup that already leans heavily on Alvarez and Peña to create offense.
Neither of these injuries is the kind of headline-grabbing news that will dominate the broadcast, but both are the type of attrition that shows up in a low-scoring elimination-format game where every at-bat and every defensive rep is magnified.
The Bullpen Battle Is the Real Series Decider
Houston’s trump card is Josh Hader, who was automatic all season — a 1.01 ERA and a perfect 26-for-26 in save chances. If this game is within two runs in the ninth, Houston’s win probability jumps enormously the moment Hader’s name gets called, and Chicago’s lineup needs to have this game decided before the ninth inning to have a real shot.
That’s where I think the betting market is underselling Chicago slightly. The total sitting around 8 runs assumes both bullpens hold reasonably well, but Houston’s rotation ERA as a group sat at 4.81 this season — solidly middle-of-the-pack — and tonight’s bullpen game format means Houston is leaning on relievers who didn’t pitch a full workload as starters all year. If Chicago’s lineup, which has been genuinely disciplined and situational all September, can push Blubaugh out of the game early and get into Houston’s middle relief before Hader is even a conversation, this game is very winnable.
What Actually Decides Game 1
Three things I’m watching as this game unfolds: how many clean innings Hagen Smith gives the Sox before Venable has to go to the pen, whether Vargas or Murakami can produce one loud swing against Houston’s non-Hader relievers, and whether Montgomery’s strikeout issue rears its head in a big spot. If Chicago’s bullpen matches zeroes with Houston’s for six or seven innings, I like this lineup’s chances to scratch across the game-deciding run late, because contact-oriented offenses tend to travel better in low-scoring playoff environments than boom-or-bust ones.
Houston is the better team on paper, the division champion, and the home team with real playoff pitching depth in reserve for Games 2 and 3. I’m not picking against that lightly. But a true bullpen game strips away Houston’s biggest individual advantage — its top-end starting pitching — and hands this game to whichever lineup executes better in a low-scoring, situational environment. I think that’s Chicago’s game to lose more than the moneyline suggests.
My Final Score Prediction: Chicago White Sox 4, Houston Astros 3 (White Sox win Game 1 and cover the run line)
