Last Updated: July 30, 2025 5:08 PM EDT • 4 minute read X Social Google News Link

The A's have enjoyed playing spoiler in the AL West recently, but my Mariners vs. Athletics prediction expects the reign of terror to come to an end tonight.
The best sports betting sites list Seattle as a sizable betting favorite (-145) in the rubber match. First pitch is set for 10:05 p.m. ET (MLB Network) from Sutter Health Park in Sacramento, Calif.
My Mariners vs. Athletics best bets anticipate the A's having some success at the plate - specifically, Tyler Soderstrom - but ultimately falling short against their familiar foes.

Mark Kotsay's men have single-handedly shaken up the American League West race over the last couple of weeks. They dropped three games to Texas before sweeping a four-game set at Houston, and now a series win over Seattle is so close they can taste it. However, my Mariners vs. Athletics prediction expects the visitors to crash the party tonight.
It's been a tale of two starts for Bryan Woo against the A's this season. He's pitched six frames in both, allowing one run in the first meeting and five runs in the second. However, he's generally been rock solid recently. Woo has given up three or fewer runs at a 70% clip across his last 10.
Meanwhile, Jeffrey Springs' splits are worse at Sutter Health Park (4.27 ERA) than they are away from home (4.01 ERA). The Sacramento park favors the slightly more powerful lineup of Seattle, a sentiment that Andrew Brennan shares in his best home run predictions tonight.
As such, my Mariners vs. Athletics best bet looks to the visitors to keep pace with the AL West-leading Astros and take the three-game series. The best sports betting apps price Seattle moneyline at -145 in the all-important rubber match.

While the aforementioned Woo has been solid against the Athletics, one player who has gotten the better of the starter so far is Soderstrom. My Mariners vs. Athletics player prop looks to capitalize on this success with a sneaky singles pick.
Soderstrom is 4-for-13 (.308) against Woo across his first three seasons in the majors. Three of those four hits were singles, and seeing as the 23-year-old has registered base knocks in each of the first two games of the series, I feel comfortable backing him to go Over 0.5 singles again.
Bettors have a true pick of the litter among the best sportsbooks with this play. BetMGM, bet365, and DraftKings all have a more favorable price (-105) than the standard vig offered elsewhere.

❓MLB betting FAQs
How do betting odds work?
Betting odds represent the probability of a specific outcome and determine how much money you can win on a bet. There are three main formats: American odds, Decimal odds, and Fractional odds. In the U.S., American odds are most common.
What is the run line in baseball?
The run line in baseball is a form of point spread betting unique to MLB. It typically sets a standard spread of 1.5 runs, meaning the favored team must win by at least two runs to cover the run line, while the underdog can lose by one run or win outright to cover.
What does moneyline mean in betting?
The moneyline in betting refers to a wager on which team or player will win the game outright, with no point spread involved. It’s the most straightforward type of sports bet - just pick the winner.
