Portland Timbers vs. St. Louis City SC: Moneyline Breakdown
The Consensus Favorite
St. Louis City SC is the favorite across every book posting a line. Their pricing runs from -164 (LeoVegas) to -204 (PMU), a meaningful gap. PMU is a clear outlier, pricing St. Louis roughly 25 cents juicier than the rest of the market. Bettors targeting a St. Louis moneyline should avoid PMU and look to LeoVegas at -164 or Kalshi at -169. Getting -164 versus -204 is a significant difference in what you're risking for the same potential return.
The Underdog Case for Portland
Portland's best available price is +400 at LeoVegas, with most books in the +355 to +375 range. PMU again sits at the bottom, offering only +340 for the Timbers. The difference is not trivial: a $100 bet at +340 returns $440 total, while the same bet at +400 returns $500. Line shopping on the Portland moneyline has a direct dollar impact.
The Draw
Soccer markets carry a three-way outcome, and the draw is priced between +310 and +370. PMU offers the lowest price at +310; LeoVegas sits highest at +370. That range implies a draw probability of roughly 21-24%, in line with typical draw rates in competitive MLS knockout situations.
The Totals Market
Most books are using a line of 3.5 goals, priced at -114 on both sides. Grosvenor posts the same 3.5 total but bumps the juice to -118 on both sides. PMU is again the worst option here, listing -132 on both the over and under at 3.5.
With most books at -114 each way, the market has no strong lean on goals. It is effectively a coin flip on whether combined scoring clears 3.5.
