The Chicago White Sox opened their 2026 postseason campaign with a commanding 5 to 0 victory over the Houston Astros on Tuesday night, taking control of their American League Wild Card Series at Daikin Park.
Chicago struck early and never allowed Houston back into the game, combining aggressive offense with an outstanding pitching performance led by rookie Hagen Smith.
The victory gives the White Sox a 1 to 0 advantage in the best of three series and puts Houston under immediate pressure heading into Game 2.
For Chicago, the result continues one of the most remarkable turnarounds in Major League Baseball.
White Sox strike early in Houston
Chicago quickly put Houston's pitching staff under pressure.
The White Sox scored three runs in the second inning, with Sam Antonacci delivering the biggest early hit. Antonacci drove a two run single into left field to extend Chicago's advantage to 3 to 0.
Houston starter AJ Blubaugh struggled with his command, forcing the Astros to turn to their bullpen earlier than they would have wanted.
The Astros entered the game with postseason experience throughout their roster, but Chicago looked like the more composed team from the opening innings.
The White Sox continued adding pressure as the game progressed and eventually completed the 5 to 0 shutout.
Colson Montgomery delivers a postseason blast
One of the biggest moments came from Colson Montgomery.
The White Sox slugger launched a spectacular 432 foot home run, adding another run and giving Chicago even greater control of the game.
Montgomery is part of a young White Sox core that has helped transform the team into one of baseball's biggest surprise stories.
Chicago entered the postseason with several dangerous power hitters, including Montgomery, Miguel Vargas and Japanese star Munetaka Murakami.
Murakami hit 35 home runs during his rookie season, while Vargas finished with 33.
That combination of young talent and power has turned a team that spent several seasons near the bottom of baseball into a legitimate postseason threat.
Hagen Smith dominates Astros lineup
The most impressive performance of the night may have belonged to Hagen Smith.
The rookie left hander was used as Chicago's opener and delivered three scoreless innings against a Houston lineup featuring some of baseball's most dangerous hitters.
Smith entered the postseason with a 3 to 3 record and a remarkable 1.29 ERA across his limited Major League workload.
Chicago's pitching plan worked almost perfectly.
Smith helped neutralize Houston star Yordan Alvarez, and the White Sox bullpen maintained the shutout after his departure.
The performance was particularly notable because both teams entered Game 1 using unconventional pitching strategies.
Houston started rookie AJ Blubaugh, while Chicago turned to Smith. MLB described the matchup as a battle between two rookie pitchers being used in bullpen oriented games.
Chicago's strategy ultimately worked far better.
Astros offense disappears at home
Houston entered the postseason with plenty of recognizable names.
Jose Altuve, Jeremy Peña and Yordan Alvarez give the Astros an experienced offensive core, while the franchise has become synonymous with October baseball during the past decade.
But none of that translated into runs Tuesday.
The White Sox pitching staff kept Houston scoreless throughout the game, preventing the Astros from building any sustained offensive momentum.
The result was particularly surprising given Houston's postseason pedigree.
The Astros won their eighth American League West title in the past 10 seasons after defeating the Athletics 9 to 0 in their final regular season game.
Houston finished the regular season 81 and 81 but claimed the division and home field advantage for the Wild Card round. Chicago entered at 84 and 78.
The postseason opener, however, belonged completely to the visitors.
A remarkable White Sox turnaround
Chicago's presence in the playoffs is itself an extraordinary story.
The White Sox reached the postseason after three consecutive seasons with at least 100 losses, transforming themselves from one of baseball's struggling franchises into an 84 win playoff team.
Their young roster has been central to that revival.
Now the turnaround has produced something even more significant: a postseason victory on the road against one of MLB's most experienced playoff organizations.
And Chicago suddenly finds itself only one victory away from the next round.
Pope Leo XIV sends White Sox a message
Game day also produced an unusual subplot involving Pope Leo XIV.
The Chicago born pope, a longtime White Sox supporter, sent a letter to team owner Jerry Reinsdorf that arrived around the time of the postseason opener.
Pope Leo XIV, formerly Robert Prevost, attended Game 1 of the 2005 World Series when the White Sox also faced Houston.
In his recent letter, he thanked the organization for a tribute held earlier this season and praised the role sports can play in encouraging unity and cooperation.
The coincidence was difficult for White Sox fans to ignore.
Chicago then went out and defeated Houston.
What happens next in White Sox vs Astros?
The series continues Wednesday in Houston.
Game 2 is scheduled for 5 p.m. ET at Daikin Park, with the Astros facing elimination after losing the opener. MLB's schedule lists a potential Game 3 for Thursday if Houston can extend the series.
Houston is expected to turn to Hunter Brown for Game 2, while Chicago has another opportunity to use the pitching depth that proved so effective Tuesday.
The equation is now simple.
A White Sox victory sends Chicago forward.
An Astros victory forces a decisive Game 3.
After a 5 to 0 statement win in Houston, Chicago has put itself in exactly the position it wanted.
