White Sox vs. Astros Prediction, MLB Wild Card Game 2 Odds & Best Bets (9/30)

Fact checked at 9:09 AM ET, Sep 30, 2026

Odds as of Sep 30, 8:12 AM ET

The White Sox are one win from their first playoff series win since 2005. Chicago, the AL's No. 6 seed at 84-78, beat the third-seeded Astros (81-81) 6-3 in Tuesday's opener at Daikin Park. Colson Montgomery hit a solo homer, and Sam Antonacci drove in two with a bases-loaded single. Houston, the home team in every game of this best-of-three, is now one loss from elimination.

Both clubs ran bullpen games in Game 1. Game 2 has two regular starters: Sean Burke (11-7, 3.34 ERA in 172 1/3 innings, 185 strikeouts) for Chicago and Hunter Brown (6-4, 3.19 ERA in 107 1/3 innings, 124 strikeouts) for Houston. Brown was named Houston's starter Tuesday night and pitches on four days of rest after throwing 100 pitches Friday. Burke was confirmed after Game 1.

Houston is -150 on the moneyline, with Chicago +125, close to where it opened (-153/+126) Tuesday night. The total opened at 8 and is now 7.5 (-110 both ways), and the White Sox are -175 on the run line at +1.5. Bettors are split close to evenly on the moneyline and the total.

First pitch is Wednesday at 5:00 PM ET at Daikin Park in Houston, where the roof is expected to be closed (the National Weather Service has a 40% chance of storms and a high near 92), on Peacock/NBCSN. If Houston wins, Game 3 is Thursday.

White Sox vs. Astros Predictions

• Pick #1: Hunter Brown Over 6.5 Strikeouts (+110)
• Pick #2: Braden Montgomery Over 0.5 Hits (-139)
• Pick #3: Cam Smith Over 0.5 Hits (-130)

PICK #1: Hunter Brown Over 6.5 Strikeouts (+110)

Chicago's hitters struck out 1,494 times this season, fifth most in the majors and fifth per game, and Houston's pitchers struck out eight of them in Game 1. Brown's recent form fits the matchup.

He reached seven strikeouts in four of his last five starts: 10 against Atlanta on Sep 20, 10 against Kansas City on Sep 15, seven against Philadelphia on Sep 9 and seven against these White Sox on Sep 3, when he went six innings and allowed two earned runs on 101 pitches. The one miss was his last start, four strikeouts in 5 1/3 innings against the Athletics on Friday. For the season he has 124 strikeouts in 107 1/3 innings. RotoWire and MLB.com both project Chicago to run out the same nine hitters who started Tuesday.

There's no reported pitch limit or opener plan, and he threw 90 to 101 pitches in each of those five starts, getting at least 15 outs every time. We like getting plus money here; +110 implies 47.6%.

Walks are how this loses. His walk rate jumped from 2.77 per nine innings in 2025 to 4.61 this year, and a few long innings early could end his night short of seven, especially in an elimination game with Houston's relievers ready. Tatsuya Imai wasn't used in Game 1 and is available behind him. The Under is -140, so the market leans slightly the other way. Strikeout props usually require the listed pitcher to start; check your book's rules. The White Sox lineup isn't posted. If you'd rather bet his innings, Brown Over 14.5 Outs (-170) is the alternative: he got 15 outs in each of those five starts, though three of them stopped at exactly 15.

PICK #2: Braden Montgomery Over 0.5 Hits (-139)

Montgomery has 10 hits in his last five starts and at least one in each. He had two in Game 1 batting seventh, one Sep 27 against Colorado, two Sep 25 against Colorado, two Sep 24 at Kansas City and three Sep 23 at Kansas City.

He started in right field in all five and batted ninth in three of them, so the streak didn't come from a move up the order. RotoWire projects him ninth Wednesday; MLB.com keeps him seventh. Both projections keep the same nine hitters that beat Houston on Tuesday. Chicago has reported no new injuries entering Game 2, and Chase Meidroth, who is playing through a left hamstring strain, started Tuesday.

This does cut against Pick 1, which needs Brown striking out Chicago's hitters, and a bottom-of-the-order bat might only come up three times. Both can still cash. Brown can get seven strikeouts over 15 or more outs and give up a single to the bottom of the order, and Montgomery had two hits Tuesday in the same game Houston struck out eight White Sox. The lineups aren't posted, so his start and spot are projections. At -139, a hit is priced at 58.2%. Sam Antonacci, who has hit in each of his last five games, is the Chicago alternative at -189 (Over 0.5 Hits), and Christian Walker Over 0.5 Hits (-174) is the Houston option.

PICK #3: Cam Smith Over 0.5 Hits (-130)

This one sits on the other side of the game. It depends on Houston's hitters against Burke and Chicago's bullpen, not on Brown, so it doesn't overlap with the first two picks.

Smith has a hit in four of his last five starts, all in right field and all batting seventh or eighth: one in Game 1, two Sep 27 at the Athletics, none Sep 26, and one each Sep 25 and Sep 24, also against the Athletics. That's five hits in five games. He hasn't been moved around the order or rested, and Houston's injury news for the series is about left-handed reliever Steven Okert (out with a right hamstring strain), not the lineup. MLB.com's Game 2 preview has Houston moving Jose Altuve to designated hitter, Yordan Alvarez to left field and Nick Allen in at second base; RotoWire keeps Altuve at second. Both have Smith in right, batting eighth.

The bullpen angle helps. Chicago wants Burke to go deep after Game 1's bullpen game. Closer Grant Taylor threw a career-high 54 pitches Tuesday, and while he said he wants the ball Wednesday, his availability is uncertain after that workload. Hagen Smith, who opened Game 1, threw 38 pitches. If Burke leaves early, Cam Smith's later at-bats come against Chicago's middle relief.

Burke is no soft touch, though. He has been Chicago's steadiest starter, opponents hit .225 against him this season, and he allowed no earned runs over 5 2/3 innings against Houston on Sep 1. Smith went hitless Sep 26, and a bottom-of-the-order hitter can get as few as three plate appearances. Houston's lineup isn't posted either, and -130 implies 56.5%. Lucas Spence Over 0.5 Hits (-129), with a hit in four of his last five starts, is the alternative from Houston's lineup.
