Mariners vs A's Expert MLB Picks, Prop Bets
The Athletics are set to host the Mariners on Wednesday afternoon in what will be the last of a three-game homestand at their temporary home in Sacramento at Sutter Health Park.
Seattle's 29-year-old righty Logan Gilbert will take the mound for the visiting Mariners, while left-hander Jeffrey Springs is set to be on the bump for the Athletics.
While the Mariners’ Gilbert has consistently been one of baseball’s top pitchers over the last few seasons, their 6 '6 righty has struggled across his first 11 starts of the 2026 season.
In over 62 innings pitched on the mound thus far, Gilbert has recorded a mediocre 4.04 ERA thus far. That said, the Mariners’ righty has had a far more efficient WHIP on the mound this season, ranking inside the top-30 amongst all starting pitchers at 1.11.
Upon starting his 2026 campaign in unbelievable form with Springs having recorded a quality start in four of his first five starts of the season, the Athletics' lefty has fallen off big time and now has posted a 4.11 ERA on the season.
Like Gilbert, Springs has a far more efficient WHIP as well, at 1.17, but could definitely have some trouble on Wednesday afternoon, having to face a very versatile Mariners lineup from 1 to 9.
However, the same can be said for Gilbert, as the Athletics boast tremendous young talent, featuring the likes of Nick Kurtz and Tyler Soderstrom, among several others.
How To Make Mariners vs A's Picks
For my first betting angle ahead of Wednesday afternoon’s AL West showdown, I will be looking to target the Athletics’ first baseman and superstar young slugger, Nick Kurtz, who is currently one of the hottest hitters in all of baseball.
The former 2024 fourth overall draft pick is coming off an insane rookie campaign in which the Athletics’ left-handed slugger smashed 36 homers in just 117 games.
While Kurtz had a case of the “sophomore slump” earlier this season, with the 23-year-old having struggled mightily at the plate over the first few weeks of the season, the Athletics’ youngster has finally started to revert to his rookie form.
Kurtz has recorded a hit in 19 of his 22 games in the month of May, and now ranks eighth in the Big Leagues with 37 RBIs. He is batting .424 AVG over the last three weeks and just surpassed Ricky Henderson’s incredible 46-game on-base streak.
His staggering 21.7% walk rate this season really conveys his exceptional discipline at the plate, as he rarely finds himself behind in the count.
Kurtz stands at 6'5" and 240 lbs with impressive patience in the box and exceptional raw power, often generating elite exit velocities and hard-hit rates at the plate.
While the Athletics’ lefty went hitless as a rookie against the Mariners’ righty, Kurtz is 1-for-2 against Gilbert this season, having drawn a walk as well.
Though I very much respect Gilbert's high-velocity arsenal on the mound, featuring an elite four-seam fastball and an effective slider, his lackluster form in 2026 gives me pause, especially having to face a hitter of Kurtz’s caliber currently in the midst of a historic hot streak and uncanny ability to reach the base paths.
Given his elite ability to draw walks, I will be looking to target Kurtz to exceed his 1.5 HRR (Hits + Runs + RBIs) mark on Wednesday night, fully expecting the Athletics’ youngster to record at least one hit and to reach the base paths safely.
As a secondary betting angle, it should come as no surprise that I favor backing Kurtz to smash a homer on Wednesday afternoon, especially given Gilbert’s high susceptibility to heavy damage against left-handed power hitters.
Pick: Nick Kurtz Over 1.5 HRR / Kurtz 1+ Home Run (+616, DraftKings)
