Current moneyline pricing lists the Brewers at +120 and the Phillies at -142 for tonight’s 6:40 PM ET first pitch.

That market puts Philadelphia in the favorite role at Citizens Bank Park, while Milwaukee offers plus-money value despite entering the matchup with a dominant 98-58 overall record. Under Manager Pat Murphy, the Brewers recently locked up their fourth consecutive NL Central title and are playing with immense confidence. On the other side, the Phillies counter with an 86-70 record, but Philadelphia’s roster is currently in flux, with recent bullpen shuffling and interim manager Don Mattingly actively managing starter innings as the postseason grind continues.

Once Polymarket prices post, they will be expressed as a Yes % (cents on the dollar), which directly correlates to the implied win probability. For reference, a traditional Brewers +120 moneyline implies roughly a 45.5% break-even probability, while Phillies -142 implies roughly 58.7% before accounting for sportsbook hold. If Polymarket’s Brewers Yes price opens meaningfully below that +120 benchmark, Milwaukee could become an attractive value target; if the Phillies trade cheaper than their -142 implied probability, Philadelphia may offer the stronger market angle.
