Oakland Athletics vs Seattle Mariners Picks and Predictions May 5th 2025

Upstart A’s Aim to Stay Hot as Mariners Roll into Sacramento

The surprise story of the American League West this season? Look no further than the Oakland Athletics. With a winning record 35 games into the season and a recent move to West Sacramento energizing the franchise, the A’s are writing a fresh chapter — and it continues Monday night against the first-place Seattle Mariners.

The two teams split a four-game set to open the year, but a lot has changed since. Oakland’s young core has caught fire, winning nine of their last 12 games, while Seattle just had a six-game win streak snapped in a lopsided 8-1 loss to Texas.

Heading into this three-game series, the Mariners still lead the division, but the A’s are just two games behind, riding confidence, grit, and a batch of fresh talent.

A’s Finding Life After Oakland

After three straight seasons with over 100 losses, no one expected Oakland to be relevant in May. But moving away from the cloud of relocation drama in Oakland seems to have breathed life into this roster.

Manager Mark Kotsay gave his squad props after Sunday’s 3-2 win over Miami

That win came on a clutch rally in the ninth — Nick Kurtz, the No. 4 pick in the 2024 draft, ripped his first career triple and Tyler Soderstrom delivered the go-ahead RBI single. Not bad for a pair of rookies.

Kurtz, who was slugging in Triple-A just weeks ago, reflected on his early MLB experience:

His mindset mirrors the entire team’s approach — hard contact, smart baseball, and youthful energy.

Mariners Looking to Bounce Back Behind Bryce Miller

Despite Sunday’s stumble against the Rangers, Seattle has looked every bit the part of a playoff team recently. Before the 8-1 loss, they had outscored opponents 50-14 during a six-game tear.

Bryce Miller (2-3, 3.52 ERA) takes the hill Monday, hoping to avenge a loss to Oakland back in March. In that game, Miller gave up three runs and a homer to Shea Langeliers, the only home run he’s allowed all year.

Still, Miller has been steady. In five career starts vs. the A’s, he owns a solid 2.73 ERA, and he’s pitched five shutout innings in both of his wins this season.

Severino Seeks Run Support in Strong Season Start

Oakland counters with veteran Luis Severino (1-3, 3.30 ERA) — a pitcher who’s arguably better than his record suggests. He’s allowed one run or less in four of his seven starts, but poor run support has kept his win total low.

Ironically, his best start of the year came against Seattle on Opening Day — six scoreless innings with six strikeouts. The Mariners still managed a 4-2 win, but Severino was sharp throughout.

Jorge Polanco (5-for-11, 1 HR) has good numbers against him, while Rowdy Tellez (2-for-12, 5 Ks) has struggled. If Severino gets just a bit of help from the A’s lineup, he’s positioned for another strong outing.

What’s at Stake in This Series?

This series could shake up the AL West standings — or solidify Seattle’s top spot. For Oakland, a series win at home would send a major message: this team isn’t just a feel-good story — it’s a real contender.

With the Mariners offense cooling off and the A’s playing loose and confident, momentum favors the underdogs. But can they deliver again in crunch time?

Keep an eye on Kurtz, Langeliers, and the A’s bullpen. If those pieces click, Oakland could walk away with the series lead by midweek.
