Athletics vs Mariners Prediction, Betting Analysis
A’s vs Mariners Player Props: Bryan Woo Outs
By Charlie Wright
Woo is an efficient pitcher and he’ll get a boost pitching at home, but there’s no reason to push him in his first start.
Woo battled injuries throughout 2024 and the Mariners handled him carefully for much of the season. He only reached 90 pitches three times in 22 starts. Woo maxed out at 78 pitches and 4 innings during Spring Training.
Seattle has gotten good length from its starting pitchers through three games. Logan Gilbert went seven innings on Thursday, Luis Castillo covered innings innings on Friday, and Bryce Miller finished with 5 2/3 innings on Saturday.
Eduard Bazardo has thrown back-to-back days and Collin Snider threw 18 pitches on Saturday. Other than those two, everyone should be available.
Closer Andres Munoz and setup man Gregory Santos have only thrown an inning apiece so far. Trent Thornton, another late-inning option, hasn’t pitched since Opening Day. Lefties Gabe Speier and Tayler Saucedo should be good to work today if needed.
It’s a solid spot and Woo will likely be effective, but there’s a well-rested bullpen behind him. I’d expect Seattle to remain cautious with his usage.
Pick: Bryan Woo Under 17.5 Outs
Athletics vs Mariners Over/Under Prediction
By Bruce Marshall
Time for fake beards and mustaches for the Seattle hitters?
Why? Across the past three nights, the Mariners have only scored six runs, and against A’s starting pitchers, they’ve only scored once (across 17 innings).
This follows last season when the Mariners offense often went into funks and suggests that maybe the offseason didn’t cure those woes.
None of the first three games in this series has cleared seven runs, and we’re not sure the A’s do a lot of business today against Bryan Woo, who posted a 2.49 ERA in 10 starts at T-Mobile park last season, and only allowed 2 earned runs in 20 1/3 IP (0.89 ERA) vs. the A’s last season.
Now, can JP Sears keep the Seattle bats off-balance on Sunday?
Pick: Under 7.5
