The matchup

The Seattle Mariners enter this matchup with a record of 9 wins and 33 losses over 42 games, displaying a concerning average of 3.3 points scored and 6.7 points allowed per game. Notably, their recent form has been especially poor, as they have lost four of their last five games. The Mariners' most recent result was a 4-7 defeat to the Athletics at home on September 4, which underscores ongoing struggles in both scoring and pitching. Their recent string of losses, including a 0-7 blowout against the Toronto Blue Jays, highlights a significant defensive collapse during the season.

On the other hand, the Oakland Athletics have fared similarly poorly this season, recording 12 wins and 35 losses across 47 games, with a scoring average of 3.6 points for and a staggering 7.7 points against per game. They secured a notable recent victory against the Mariners (7-4) just prior to this upcoming clash but were not without their own troubles, suffering losses in their previous three matches against the Texas Rangers and the Baltimore Orioles. Given that both teams have allowed more runs than they have scored throughout the season and considering their recent head-to-head clash, fans may anticipate another competitive meeting with numerous scoring opportunities.

Does the price match the form?

The current best-of-market decimal odds show the Seattle Mariners at $1.47, reflecting a 68.0% implied probability, while the Athletics are positioned at $3.05, carrying an implied probability of 32.8%. The total market adds up to 100.8%, which indicates a slight bookmaker margin embedded in these figures.

When comparing these implied probabilities with the recent results, the 68.0% implied probability for the Mariners does seem elevated given their ongoing struggles, particularly their recent loss to the Athletics. This prompts the question: is the market overvaluing the Mariners based on their home advantage, or is there something in their performance that suggests a reversal in form is imminent? Furthermore, do the Athletics' recent win and similar subpar performance warrant their higher odds, or does their head-to-head victory suggest that they may have an edge?

Where to look in the markets

  • Head-to-Head: The Mariners are currently favoured, but their poor record raises questions about whether this should be the case, particularly after the Athletics' recent victory.
  • Totals Over/Under: Both teams combine for a scoring average of about 7 total points, suggesting that it’s worth investigating the posted totals line, which could be reflective of their erratic scoring patterns.
  • Relevant Player Props: Given the recent defensive issues for both sides, looking at player performance props, especially for those involved in scoring, could yield valuable insights.

Staking this game

With the Seattle Mariners priced at $1.47, you would need them to achieve a 68% strike rate just to break even. It’s advisable to consider a disciplined staking approach, such as flat staking of 1-2%, to endure the inevitable losing runs that can occur even when backing strong favourites.
