After the match

Writing a quick retrospective on how the market read this one…

The matchup

The St. Louis Cardinals are entering this matchup with a record of 25 wins and 34 losses from their 59 games this season, averaging 4.4 points for and against. Their last five games have been disappointing, with three consecutive losses against the San Francisco Giants, followed by a recent 1-9 blowout defeat against the Washington Nationals on September 19. This recent streak demonstrates both a lack of scoring stability and defensive weaknesses, especially considering that they allowed the Nationals to score nine runs in that game.

On the other hand, the Washington Nationals hold a record of 24 wins and 38 losses across 62 games, averaging 5.0 points for and 4.9 against. Their recent form shows more promise, particularly highlighted by their significant victory over the Cardinals. They have notched a string of solid performances against the Philadelphia Phillies and Los Angeles Angels leading into this matchup, demonstrating their offensive capability by scoring six runs in two of their last four games. The head-to-head results this season are notably one-sided in favour of the Nationals, with their 9-1 victory against the Cardinals just a day prior amplifying the importance of their form heading into this game.

Does the price match the form?

The market currently lists the St. Louis Cardinals at $1.72, which reflects a 58.1% implied probability of winning, while the Washington Nationals are at $2.25, with an implied probability of 44.4%. The total market probability stands at 102.6%, indicating a bookmaker margin of 2.6% above 100%.

Examining the implied probability of the Cardinals, there seems to be a disconnect when compared to their recent performances. Despite being favoured according to the odds, the Cardinals have lost their last match against the Nationals and three of their last five games overall. Their form suggests instability, particularly in both scoring and defence, which may warrant further investigation into whether the market view aligns with the reality of their current performance. Are the Cardinals truly the stronger side given their recent results, or is the market overvaluing their chances based on their home advantage?

Where to look in the markets

Considering the data at hand, a few markets warrant closer scrutiny for this matchup. First, the totals over/under market could be appealing, as the combined scoring average for these teams based on their season statistics is about 9 total points. Evaluating this figure against the bookmakers’ posted line should give insights into potential scoring outcomes.

Additionally, examining the head-to-head market is crucial, particularly after Washington Nationals’ recent 9-1 victory over the Cardinals, which may shape perceptions and adjustments in odds. The margin market could also provide value, especially since the Cardinals have exhibited defensive lapses recently, notably allowing high run totals in consecutive games. This suggests a potential for variation that warrants investigation.
