White Sox vs. Guardians Prediction, MLB ALDS Game 1 Odds & Best Bets (10/3)

Fact checked at 9:30 AM ET, Oct 3, 2026

Odds as of Oct 3, 5:36 AM ET

One game separated these teams over 162. Cleveland (85-77) won the AL Central by that game and earned a first-round bye, while Chicago (84-78) had to sweep the Astros in the Wild Card Series, 6-3 and 7-3, to get here. The head-to-head was even tighter: the White Sox took the season series 7-6 and outscored Cleveland 58-57.

Both clubs send rookie left-handers to the mound for Game 1 with very different jobs. Parker Messick (12-9, 2.56 ERA over 186.1 innings) makes a normal start for Cleveland on five days' rest. Hagen Smith, who posted a 1.29 ERA in 28 regular-season innings, opens a bullpen game for Chicago, the same role he filled with three scoreless innings in the Wild Card opener. Manager Will Venable has said Smith and closer Grant Taylor could pitch in each of the first three games.

The consensus has Cleveland -155 and Chicago +130, with a total of 7 (Over -100, Under -120). Cleveland opened as a somewhat bigger favorite, and the total has come down from 7.5 at some books to 7. First pitch at Progressive Field is 1:00 PM ET Saturday on TBS and truTV, and the forecast is sunny and about 64 degrees with a light northeast wind and no rain. Lineups aren't posted yet. The two hitter picks assume Colson Montgomery and Kyle Teel are in Chicago's lineup, and the third assumes Smith opens. If either hitter sits or Smith doesn't open, drop that pick. Prop prices are as of 6:13 AM ET.

White Sox vs. Guardians Predictions

• Pick #1: Colson Montgomery Under 0.5 Hits + Runs + RBIs (+103)
• Pick #2: Kyle Teel Over 0.5 Hits (-120)
• Pick #3: Hagen Smith Under 0.5 Earned Runs (-139)

PICK #1: Colson Montgomery Under 0.5 Hits + Runs + RBIs (+103)

Montgomery is 1-for-17 over his last five starts, and four of those five ended without a hit, a run or an RBI. Chicago has already noticed. Venable batted him ninth for the first time all season in the Wild Card opener, kept him there for Game 2, and the projected lineup against Messick has him ninth again. That spot got four plate appearances each night in Houston, one fewer than the top of the order.

This isn't a one-week dip. Since Sept. 23 he is 1-for-23 with 11 strikeouts, and he closed the regular season 4-for-62 with 34 strikeouts over his final 19 games. Messick struck out 29 White Sox in 25.2 innings over four starts this season, and Montgomery is 9-for-47 (.191) against Cleveland. At +103, the implied probability is 49.3%, so you're getting a coin flip on a hitter in a deep hole.

Now the problems. He homered in Game 1 at Houston, and a guy with 31 homers only needs one swing. The prop can also lose without a hit, on a walk that comes around to score or a run driven in by an out, and he did walk in Game 2. Lefties haven't been his issue either: he hit .237 with 10 home runs against them and .179 against right-handers. On Sept. 27 he started against Colorado's left-hander, Kyle Freeland, batting seventh, and went 0-for-4. Ninth is a projection, and another projection has him seventh, which would mean a little more volume. If he's not in the posted lineup, skip it.

To avoid sweating a walk, Under 0.5 Hits (-119) takes that out of play, and nothing in his last five starts separates the two. This pick only pulls against the Teel Over in a narrow way (a Teel single puts a runner on ahead of the bottom of the order), and plenty of ordinary games cash both.

PICK #2: Kyle Teel Over 0.5 Hits (-120)

Teel has hit in six straight starts, 9-for-22 since the streak began Sept. 23, and the left-on-left matchup doesn't scare me.

The splits are close to identical: .212 against left-handers, .209 against right-handers. Messick has also been more hittable for lefties (.245) than righties (.206). Over his last five starts Teel is 8-for-19, including 3-for-10 in the Wild Card Series, with four of those starts in the No. 2 spot and one in the sixth, and he averaged 4.8 plate appearances. The only lefty starter he saw in that stretch was Jose Quintana on Sept. 26. Teel batted sixth that day and got two hits. The -120 price implies 54.5%.

My worry is the lineup card. The projection against Messick has Teel seventh, not second, and a seventh-place hitter won't get the 4.8 trips a night he's been getting. A one-hit bet leans on every plate appearance. He also sat on Sept. 27 when Colorado started the left-handed Freeland, struck out 14 times in 33 at-bats against lefties this season, and fanned three times in Game 2. After Messick, Cleveland goes to a bullpen with a 3.54 ERA and 10.21 strikeouts per nine that has had at least five days off. If Teel isn't in the lineup, skip the pick. If he's batting seventh, it still stands, just on the thinner case laid out here.

Teel Over 0.5 Hits + Runs + RBIs (-144) gives you more ways to win at a higher price. None of this conflicts with the Smith Under below, which lives on Cleveland's half of the box score.

PICK #3: Hagen Smith Under 0.5 Earned Runs (-139)

A pitcher going two or three innings doesn't have much time to give up an earned run, and that's the whole idea here.

Venable said the White Sox can "lean on some of the bullpen arms to get us through some bulk," and added that if Smith throws three innings Saturday he might need an extra day. Chicago has done this before. Smith opened the Wild Card opener at Houston with three scoreless innings on 38 pitches, and he started Sept. 10 against Pittsburgh with two scoreless innings on 33 pitches. His season highs are three innings and 48 pitches. In 18 regular-season appearances he allowed four earned runs in 28 innings (1.29 ERA) with 41 strikeouts and 11 hits, and only three of those outings had an earned run. His outs line sits at 6.5, roughly two innings. Cleveland averaged 4.19 runs a game, 24th of 30 clubs. -139 works out to a 58.2% chance.

Walks are the danger. Smith issued 16 in 28 innings, and in three relief outings against Cleveland this year he walked six in 5.2 innings and gave up two earned runs, both on Sept. 16. Cleveland's offense also looks better lately than its season number suggests: it scored 245 runs from Aug. 1 on, a stretch that includes the Aug. 3 trades for Jo Adell and Nathaniel Lowe. Cleveland's lineup isn't posted either. This bet needs Smith to open as Venable said he will. If Chicago changes course, skip it.

Hagen Smith Under 6.5 Outs (-157) bets on the short outing directly, though his three-inning start at Houston would have lost it. A low-scoring game can pay this and the Montgomery Under together: one needs Cleveland held down early, the other needs Chicago's No. 9 hitter quiet.
