Guardians vs White Sox Game 3 Prediction & Analysis: Chicago Looks to Secure Sweep
Updated October 6, 2026
Updated October 6, 2026
Chicago returns home with a chance to close out Cleveland in Game 3 of the AL Division Series on October 7 at Rate Field. The White Sox own a 2-0 series lead after winning 3-0 in Game 1 and 4-3 in Game 2, giving these clubs just 10 combined runs across the first 18 innings. Cleveland now has no room for another quiet offensive day, while Chicago can reach the ALCS with one more victory.
Model vs. Market
Polymarket had Under 7.5 priced at 48¢ as of October 6, with Over 7.5 at 53¢. That gives the under an implied probability of roughly 48%. My projection makes the under closer to a 52% outcome after accounting for the first two games, full-season offensive and pitching performance, expected pitcher usage, and bullpen availability. At the current price, that creates a 4% gap between the model and the market.
Low-Scoring Series Start
There is an important difference between saying Cleveland and Chicago are incapable of scoring and saying 7.5 is slightly too high for this specific game. Chicago averaged 4.79 runs per game during the regular season and finished with a 103 OPS+, so there is obvious scoring potential in this lineup. Cleveland averaged 4.19 runs with a 97 OPS+. Yet Cleveland also finished with a 3.77 team ERA and allowed 4.12 runs per game. More important right now, the Guardians have produced only 3 runs on 7 hits in this series. Chicago has scored 7 runs across the same 2 games. The first 2 contests finished with combined totals of 3 and 7.

Why Our Model Sees Value:
“The current price gives too much weight to Chicago's regular-season scoring ability and the uncertainty surrounding the starting pitchers. Cleveland's lack of production, the likely use of both bullpens, and rested high-leverage relievers on both sides create a better environment for another low-scoring game.”
The simplest explanation for Cleveland's 0-2 deficit is also the biggest reason to consider Under 7.5 when making a Guardians vs White Sox Game 3 prediction: the Guardians have barely hit.
Cleveland managed just 3 hits and 5 walks in the 3-0 Game 1 loss, going 0-for-3 with runners in scoring position. Game 2 offered a little more life, but the Guardians still finished with only 3 runs in a 4-3 defeat. Through 2 games, Cleveland has 7 hits, 3 runs and 8 walks. José Ramírez entered Game 3 at 0-for-6 in the series with 2 walks, while Angel Martínez was 0-for-8. Steven Kwan, Jo Adell and Travis Bazzana had recorded only 1 hit apiece.
Neither starter had officially been announced in MLB's latest Game 3 update. Cleveland has several possibilities. Tanner Bibee, Joey Cantillo, and Foster Griffin could work in traditional starting roles, while Daniel Espino could open before Cantillo handles multiple innings. That latter option is especially interesting for an under. Cantillo allowed just 4 hits and 4 walks with 17 strikeouts over 15 scoreless innings across 3 September outings behind Espino.
Chicago has similar flexibility. Hagen Smith is an obvious candidate after opening Game 1. Smith threw 2 2/3 hitless innings that afternoon and has logged 5 2/3 scoreless innings over his first 2 postseason starts. The White Sox have repeatedly shown that manager Will Venable is comfortable moving quickly from one arm to another rather than asking a pitcher to work deep into a game.
That setup can be frustrating for hitters. Cleveland may see different arm slots and pitch arsenals every trip through the order, limiting the value of seeing the same pitcher for a 3rd plate appearance.
The White Sox are clearly the greater threat to the under. Chicago scored 776 runs during the regular season, averaged 4.79 runs per game, and hit 211 home runs. Munetaka Murakami has already made his presence felt in this series, hitting a 2-run homer in Game 1 before adding an RBI single in Game 2. Miguel Vargas reached base 3 times Monday, and Braden Montgomery delivered the decisive 2-run double in the 6th inning.
Still, Cleveland has kept the damage limited. The White Sox have scored just 7 times through 2 games despite taking both contests, and Cleveland's pitchers have recorded plenty of strikeouts. Gavin Williams struck out 11 over 5 innings Monday while allowing 2 earned runs. Parker Messick gave up only 2 earned runs in 4 1/3 innings in Game 1.
Tuesday's off-day is significant because it allows both clubs to reset their bullpens. Cleveland can have Cade Smith, Hunter Gaddis, Erik Sabrowski, and Shawn Armstrong available in an elimination game. Chicago closer Grant Taylor should also be ready after needing just 7 pitches in Game 2. Taylor previously worked 4 scoreless innings while earning the save in Game 1, giving Chicago a powerful option if it carries a lead into the later innings.
Chicago has held Cleveland to 3 runs across 18 innings in this series. Game 1 required 5 White Sox pitchers, and Sean Burke then gave Venable 5 1/3 innings of 1-hit relief in Game 2 while striking out 6. He retired 13 consecutive Cleveland hitters during that appearance.
Under 7.5 is the better side of the current Polymarket price. Chicago's lineup is capable of producing a crooked number, and the lack of confirmed starters keeps this from being an extremely high-confidence play. Even so, the evidence through 2 games points to another contest where pitching changes come early, and high-leverage relievers enter before either lineup gets repeated looks at vulnerable arms.
Cleveland has scored only 3 runs in the series, Chicago has scored 7, and both previous games stayed below 7.5. With rested bullpens, an elimination-game pitching plan for Cleveland and Chicago likely turning to several arms again, my projection puts the probability of 7 or fewer total runs at 52%.
