The matchup

The Seattle Mariners enter this matchup with a dismal record of 1W-10L over their last 11 games, averaging just 2.6 runs scored while allowing a staggering 5.5 runs against. Notably, their last five games feature a consistent pattern of losses, including two shutouts against the San Francisco Giants where they lost 0-7 on July 18 and July 19, both at home. This poor form raises concerns about their offensive capability and their ability to compete effectively in this matchup.

In contrast, the Cincinnati Reds have fared somewhat better, with a record of 5W-9L over their last 14 games, and an average of 2.7 runs scored versus 2.9 runs allowed. Their recent performance is marked by a three-game winning streak against the Colorado Rockies, where they posted victories of 7-2 on July 18 and 19. This includes a strong performance where they scored four runs without reply against the Chicago Cubs in a home series earlier in July. While both teams are struggling to find consistent scoring, the Reds' recent success could be a significant factor heading into this game.

Does the price match the form?

The current best-of-market decimal odds are as follows: Seattle Mariners at $1.67 with an implied probability of 59.9%, and Cincinnati Reds at $2.37 with an implied probability of 42.2%, leading to a market total of 102.1%. Reflecting on these figures, the Mariners' implied probability suggests they are indeed favoured, but does this align with their recent performances? Given the Mariners' singular win in their last 11 games, it raises the question: is the market being too bullish on the home side given their recent form and lack of offensive output?

Where to look in the markets

When considering which markets to explore, the totals over/under is an area worth investigating. The combined scoring average of both teams stands at around 5 total points, so it’s essential to compare the bookmaker's posted line against this average. Additionally, since the Mariners are struggling offensively, looking at potential margins could be insightful, particularly considering the Reds' recent scoring explosion. Exploring the head-to-head market could also be beneficial, given that the Reds have shown the ability to secure wins against stronger teams, contrasting with the Mariners' current form.

Staking this game

The Mariners are priced at $1.67, requiring a 60% strike rate just to break even. Given their recent form, a conservative 1-2% flat staking strategy could help manage risk, as it is vital to account for the losing runs that can arise even with a strong favourite.
