White Sox vs Astros Game 2 Prediction, Preview & Analysis - 9/30/2026
Updated September 30, 2026
Updated September 30, 2026
The Chicago White Sox have a chance to finish the job Wednesday after taking Game 1 of the American League Wild Card Series 6-3 in Houston. Chicago struck early Tuesday, received 3 scoreless innings from Hagen Smith, and never gave up the lead. Houston now turns to Hunter Brown with its season on the line, while the White Sox counter with Sean Burke, their most reliable starter across the regular season. First pitch at Daikin Park is scheduled for 5 p.m. ET.
Why Our Model Sees Value:
“Houston deserves to be favored with Brown on the mound and home-field advantage, but a 59% implied probability gives too much weight to Brown's presence on the mound and Houston's regular-season success against Chicago. Burke's performance against the Astros, Chicago's superior season-long pitching numbers, and the price available on the White Sox make the underdog more attractive.”
Brown Impacting Houston's Pricing
The current Polymarket price has Houston at 59¢ and Chicago at 42¢. That is a considerable move toward the Astros compared with the pricing around Game 1, and Brown is the obvious reason. He finished the regular season 6-4 with a 3.19 ERA, 1.27 WHIP and 124 strikeouts in 107 1/3 innings. He was especially effective against Chicago, going 2-0 with a 1.38 ERA in 2 starts. There is a legitimate case for Houston being the more likely winner Wednesday. The issue is how much more likely.
What Our Projections Say
My projection lands closer to Houston at 55.5% and Chicago at 44.5%. That leaves the White Sox about 2.5% above their 42% Polymarket price. Burke helps close what might appear to be a large starting-pitching gap. He finished 11-7 with a 3.34 ERA, 1.20 WHIP and 185 strikeouts in 172 1/3 innings, and Houston has already seen how difficult he can be. Burke threw 5 2/3 scoreless innings at Daikin Park on September 1, allowing 1 hit while striking out 6. He also struck out 10 Astros over 6 innings in July.

Chicago could hardly ask for a better starter to have available with a chance to end this White Sox vs Astros series. Burke produced a 3.34 ERA across 172 1/3 innings and struck out 185 batters while holding opponents to a .225 average.
His recent form is another positive. Burke allowed just 1 run over 5 1/3 innings against Colorado in his final regular-season appearance, earning his third consecutive win. Before that, he held Detroit to 1 run over 6 innings and Cleveland to 1 run over 5.
Houston has also seen Burke twice this season. His September 1 outing was the more impressive of the 2, as the Astros managed only 1 hit in 5 2/3 scoreless innings. His command was not perfect, but Houston could not turn 4 free passes into runs.
The Astros could not use Brown in Game 1 because of the way their rotation lined up at the end of the regular season. They now get their best available starter on normal rest in an elimination game.
Brown's 3.19 ERA was backed by 124 strikeouts and only 81 hits allowed across 107 1/3 innings. He was also excellent down the stretch. In his final 3 regular-season starts, Brown allowed 2 earned runs across 15 1/3 innings while striking out 24.
Chicago has had trouble solving him. Brown allowed 2 runs over 6 innings in a 6-2 Houston victory on September 3, and Houston benefited from a 1.38 ERA for Brown across his 2 starts against the White Sox this season. His career numbers against Chicago have also been excellent.
The White Sox did not look overwhelmed by the postseason stage Tuesday. Sam Antonacci drove in 2 runs, Colson Montgomery homered, and Chicago built a 5-0 advantage before Houston finally scored.
Montgomery is a particularly interesting matchup against Brown. His strikeout total became an issue late in the regular season, but his power gives Chicago a way to change the game with one swing. Munetaka Murakami also finished the regular season with 35 home runs, while Miguel Vargas was one of Chicago's most consistent offensive contributors.
Brown should generate strikeouts against this lineup. Chicago's best path is probably getting runners aboard through walks or singles and then finding one extra-base hit in a high-value situation.
Houston finished the regular season with 226 home runs, the most in the majors, and Yordan Alvarez remains the hitter Chicago has to fear most. Alvarez finished at .316 and led Houston with 42 home runs and 106 RBIs.
Chicago kept him from controlling Game 1. Alvarez finished 1-for-4, and Houston did not score until Nelson Velázquez hit a 2-run homer in the fifth. Jose Altuve helped create another run later, but the Astros spent most of the afternoon trying to recover from an early deficit.
Burke's biggest task is limiting Alvarez, Jeremy Peña, Isaac Paredes and Altuve at the top of the order. Houston has enough power that Burke does not need to make many mistakes before the outlook changes.
Houston has the stronger starting pitcher in this game, home-field advantage, and an offense capable of producing several runs with very little warning. Those factors justify making the Astros the favorite.
But Burke's 2026 numbers are close enough to Brown's to keep the starting-pitching difference manageable, and his previous success at Daikin Park provides additional evidence that Houston's lineup is not a poor fit for him. Chicago also enters after showing it can pressure Houston's pitchers, get production throughout the order, and protect a lead.
At 42¢, the White Sox do not need to be the more likely winner to offer the better price. My model gives Chicago a 44.5% chance of taking Game 2 and ending the series. That makes Chicago White Sox to win at 42¢ my recommended prediction.
