The 2026 ALDS comes down to one game. The Chicago White Sox and Cleveland Guardians play a deciding Game 5 at Progressive Field tonight, with first pitch at 8:00 pm ET and the series tied 2-2. Chicago won Game 1 3-0 and Game 2 4-3. Cleveland answered with a 9-3 win in Game 3 and came back from an 0-2 deficit to force tonight's game. The winner faces Tampa Bay in the ALCS.
Sean Burke starts for Chicago. He went 12-7 with a 3.37 ERA in the regular season. Gavin Williams starts for Cleveland after a 14-8 regular season with a 3.75 ERA. Our pick is Under 7.5 runs.
The number
- Model total: 7.0 runs. - Pick line: 7.5. The model engine's market reference shows 8.5. Current listings we found range from 7 to 7.5. We grade this pick at 7.5. - Model probability: n/a. Market-implied probability: n/a. Edge: none quantified. - Model confidence: 56.9 (engine output, on the model's internal scale).
No edge figure was generated for this pick, so we are not publishing one. Against 7.5, the model's 7.0 sits half a run under the line. Against the 8.5 reference, it sits 1.5 runs under. The direction is consistent across both numbers. The size of the cushion depends on which line you are looking at. At 7.5, it is thin.
A confidence reading of 56.9 is a modest lean, not a strong signal. We record this pick on the public ledger at the line stated above, win or lose.
Why the model leans this way
The totals. The model's 7.0 is below every market number we have: 7, 7.5 and 8.5. Most of the market has already moved toward a lower-scoring game. A 7.5 line means the game must stay at seven runs or fewer for the Under to win. The projection lands right at that threshold.
The park is neutral. Progressive Field carries a park factor of 1.0. The environment does not add runs, and it does not take them away. The lean comes from the matchup, not the venue.
The offenses are close and modest. The model rates Cleveland's offense at 36.9 and Chicago's at 35.3. That is a 1.6-point gap, and neither lineup grades as a run-producing outlier on the model's scale.
The starting pitching. Burke's postseason line is 1-0 with a 3.86 ERA, a 0.64 WHIP and 14 strikeouts in 9.1 innings. A WHIP that low means very few baserunners, which limits multi-run innings. Williams has a 3.00 ERA with 12 strikeouts in 6.0 innings this postseason. Both starters are missing bats at a high rate in October.
Series scoring. Two of the three results we have stayed low: 3-0 (3 total runs) and 4-3 (7 total runs). Both would have cleared an Under 7.5.
Late-inning structure. Cleveland was 62-5 when leading going into the 7th inning in 2026. Closer Cade Smith recorded 41 saves. If Cleveland leads late, the innings that follow have tended to be controlled.
Form. Cleveland has lost 1 straight and Chicago has won 1 straight. In a one-game series, single-game streaks carry little weight, and the model does not lean on them.
The case against
Game 3 shows how the Under loses. Cleveland's 9-3 win produced 12 runs. The same two lineups have already shown they can break a low total open in this series.
Burke allows home runs. Despite the 0.64 WHIP, Burke has allowed 3 home runs in 9.1 postseason innings. A low WHIP keeps runners off base, but solo and two-run homers can push a game past 7.5 without many baserunners.
Chicago has two power bats. Munetaka Murakami hit 35 home runs this season, even with a .207 average. Miguel Vargas hit 33 homers with 93 RBI. Against a starter who has been vulnerable to the long ball, these two hitters are the clearest threat to the pick.
Small samples. Williams' 3.00 ERA covers 6.0 innings. Burke's numbers cover 9.1 innings. Postseason lines this short can shift quickly, and a single rough inning from either pitcher could undo the case built on them.
Ordinary variance. The line sits half a run above the projection. Games near a total land on either side often. One extra-base hit with runners on, or a defensive mistake, decides an Under like this one. Treat this as a modest lean, consistent with the 56.9 confidence reading, not a near-certainty. We do not have a model probability to state how often the Over wins. Read the pick as close to a coin flip with a slight tilt toward the Under.
Elimination-game managing. Both managers are likely to go to their bullpens aggressively. That can suppress scoring, but it also exposes more relievers. Any one of them can have an off night.
The pick stands: Under 7.5. The model total is 7.0, the confidence reading is 56.9, and no edge was quantified. It will be logged and graded on the ledger like every other pick.
