The Chicago Cubs (92-70) and Milwaukee Brewers (97-65) clash in Game 1 of their NL Division Series at American Family Field on Saturday afternoon. This series opener sets the tone for two fierce NL Central rivals, with the Cubs turning to Colin Rea while Milwaukee counters with ace Freddy Peralta. With Milwaukee’s dominant bullpen, home field advantage, and postseason-tested rotation, this Game 1 matchup offers several sharp betting angles for bettors looking to cash in on October baseball.
Quick Picks:
- Best Bet: Milwaukee Brewers -1.5 (+145) ★★★★☆
- Top Prop: Freddy Peralta Over 6.5 Strikeouts (-115) ★★★★☆

Chicago Cubs vs Milwaukee Brewers Betting Odds & Latest Line Movement
| Market | Chicago Cubs | Milwaukee Brewers |
|---|---|---|
| Moneyline | +131 | -157 |
| Run Line | +1.5 (-175) | -1.5 (+145) |
| Total | Over 7.5 (+105) | Under 7.5 (-125) |
Opening Line: Brewers -150, Total 7.5
Sharp Money Analysis: Where Pro Bettors Are Placing Their Wagers
The Brewers opened at -150 and have been bet up to -157, indicating professional money backing the home favorite despite nearly 60% of public tickets landing on Chicago. The total has held steady at 7.5, but the juice shifted toward the under (-125), which suggests sharp bettors anticipate a lower-scoring opener. That aligns with playoff baseball tendencies and Milwaukee’s run-prevention strength. While the Cubs +1.5 is drawing attention at -175, I see better value siding with Milwaukee’s dominance at home in this critical Game 1.
Pitching Matchup: Colin Rea vs Freddy Peralta – Who Has the Edge?
Chicago Cubs: Colin Rea (0-0, 0.00 ERA)
- Minimal postseason experience (just 1.2 playoff innings pitched)
- Strong early control, no walks issued in limited playoff work
- 0.60 WHIP shows ability to keep runners off base in small sample
- Vulnerable to power hitters during the regular season
- Inconsistent as a starter across 2025 campaign
Milwaukee Brewers: Freddy Peralta (0-0, 0.00 ERA)
- Brewers’ ace making his postseason debut for 2025
- Elite strikeout arm with a high swing-and-miss rate
- Excelled at American Family Field during regular season
- Handled Cubs’ lineup effectively in past matchups
- Fully rested and prepared for this pivotal Game 1 assignment
Advantage: Clear edge to Milwaukee. Peralta brings frontline, October-caliber stuff, while Rea profiles as more of a middle-rotation option. Peralta’s strikeout upside against a Cubs lineup averaging nearly 8 strikeouts per game gives the Brewers a significant edge in the opener.
Bullpen Breakdown
Milwaukee boasts one of MLB’s best bullpens, anchored by Trevor Megill (30 saves) and Abner Uribe (37 holds). Their swing-and-miss relief corps (8.84 K/9) gives them a huge advantage in late-inning playoff scenarios. Chicago has Daniel Palencia (22 saves) as their closer, but overall lacks the same depth and power. With October magnifying high-leverage outs, the Brewers’ bullpen edge could swing this Game 1.
Key Betting Trends & Team Statistics That Matter
- Milwaukee’s .599 win percentage bested Chicago’s .570 during the season
- Brewers’ run differential: +172 vs Cubs’ +145
- Milwaukee pitching staff strikeouts: 8.84 K/9 vs Chicago’s 7.79
- Brewers’ team OBP: .332 vs Cubs’ .320
- Cubs hit more home runs per game (1.37) but Brewers suppress runs better overall
- Milwaukee dominated the season series against Chicago
- American Family Field has been a fortress for Milwaukee in 2025
- Since the wild card era, Game 1 winners in a best-of-five win the series over 70% of the time
Abner Uribe: Milwaukee’s X-Factor
Abner Uribe might be Milwaukee’s secret weapon this October. His high-90s heater and sharp slider neutralized opposing power all season, allowing just 3 homers in 67 innings while posting a strikeout rate over 30%. Against a Cubs lineup reliant on the long ball (1.37 HR/game), Uribe is the perfect bridge from Peralta to closer Trevor Megill. His dominance in the 7th or 8th inning could easily swing Game 1 momentum.
American Family Field Factor
This ballpark plays unique in October. With a 1.139 home run factor, homers remain a big part of the scoring equation. But its 0.976 run factor suppresses overall runs, meaning power matters more than small-ball rallies. With the roof closed for playoff conditions, the ball won’t carry as much as in summer, which benefits Milwaukee’s pitching-first approach. That dynamic is a problem for Chicago’s feast-or-famine lineup and adds another layer of advantage for the Brewers in Game 1.
Expert Prediction & Best Bets for Cubs-Brewers Game 1
Primary Play: Milwaukee Brewers -1.5 (+145)
Milwaukee’s edge on the mound and in the bullpen is too strong to ignore. Peralta gives them the ability to control the opener, and with the Cubs relying on Colin Rea in his first true October test, this sets up as a multi-run Brewers win. At +145, the run line offers strong value.
Strong Value Play: Under 7.5 Runs (-125)
Game 1s often trend lower, and with Peralta’s strikeout arsenal combined with Milwaukee’s shutdown bullpen, scoring should be limited. Rea could struggle, but even if he does, Milwaukee’s staff is equipped to keep the game under control. Under is the sharper angle here.
Worth Considering: Freddy Peralta Over 6.5 Strikeouts (-115)
Peralta’s swing-and-miss stuff plays in October, and he’s exceeded this total in 3 of his last 4 outings vs Chicago. Expect him to get every opportunity to work deep in this series opener, especially if he’s commanding the fastball. At -115, this is a strong prop to back.
Player Props Worth Targeting in Game 1
| Player | Prop | Odds | Rating |
|---|---|---|---|
| Freddy Peralta | Over 6.5 Strikeouts | -115 | ★★★★☆ |
| William Contreras | Over 1.5 Total Bases | +115 | ★★★★☆ |
| Colin Rea | Under 4.5 Strikeouts | -130 | ★★★☆☆ |
| Abner Uribe | To Record a Hold | +140 | ★★★★☆ |
Final Thoughts: Brewers Poised to Take Game 1
This series opener tilts heavily toward Milwaukee thanks to Freddy Peralta’s frontline presence and a bullpen built for October. Colin Rea has been steady but doesn’t profile as a Game 1 starter in a postseason series, especially against a disciplined Brewers lineup. American Family Field, Milwaukee’s bullpen edge, and their season-long superiority create the perfect recipe for a strong start to the NLDS. Expect the Brewers to handle business in Game 1 and seize early control of the series.
Score Prediction: Milwaukee Brewers 5, Chicago Cubs 2
