Philadelphia Phillies vs. St. Louis Cardinals

Platform comparison

Market context

The game is the **Philadelphia Phillies against the St. Louis Cardinals**, and in this market a **YES** share pays out if Philadelphia wins, while a **NO** share pays out if St. Louis wins. Because the crowd price is **59% YES**, the market is implying the Phillies are a modest favourite, but not overwhelmingly so; that is consistent with a matchup where either side can plausibly win on a single night.

Recent results help frame that number. The Phillies beat the Cardinals **6-5 on 10 August**, and AP reported that Philadelphia entered that matchup on a **three-game road winning streak**. AP also noted strong recent form overall, with the Phillies going **7-3** in their last 10 and the Cardinals **5-5**, while Philadelphia had also outscored opponents by more runs over that span. Head-to-head trends are less decisive than the crowd price might suggest: Statmuse shows the Phillies are **13-7** in the last 20 meetings, but the Cardinals have taken some individual games in the series as well.

For traders, the main catalysts are straightforward: the official starter announcements, any late scratches, and whether the game is actually played as scheduled. This market stays open if the fixture is postponed until it is completed, but it resolves **50-50** if the game is cancelled without a make-up or ends in a tie, so schedule changes matter directly. Line-ups and pitching changes can move the likely winner quickly in MLB, especially in a tight matchup with a crowd price near 60/40. [1][7]
