St. Louis City SC Would Make History

No modern MLS expansion club ever has won the league’s title in their first season, with Atlanta United FC being the fastest to do so (in their second season of play in 2018). The Chicago Fire won MLS Cup as a first-year team in 1998 but the whole league was only in its third season.

St. Louis City SC has the best odds of any modern expansion club at achieving such a feat, with a clear path to the MLS Cup championship match as LAFC is on the other side of the West bracket.

So, – your source for Missouri online casinos should iGaming come to the state – sees hypothetical odds of +812 for the expansion side of winning the 2023 MLS Cup. That equals out to an 11% probability. We peg FC Cincinnati (the Eastern Conference top seed) at +355 (22%) and 2022 league champs LAFC at +600 (14.3%) on our MLS Cup odds board.

The MLS’ newest club has better Western Conference championship odds, with our metrics given them +275 odds (or 26.7%) of getting past the wild-card round winner (either FC Dallas or the San Jose Earthquakes going into Saturday), the 4/5 winner, currently the Houston Dynamo and Real Salt Lake, and a likely conference championship showdown with LAFC after that.

That road to history begins later this month, when the MLS Cup Playoffs kick off with the league’s wild card matches on Oct. 25 and 26. The 2023 MLS Cup final is slated to take place on Dec. 9.
