Oakland’s Rising Stars Power Momentum Ahead of Mariners Series

The Oakland Athletics are enjoying their hottest stretch of the season, riding a four-game sweep of the division-leading Astros into a three-game set against the Seattle Mariners. The action shifts to West Sacramento, where Oakland hopes their youth movement continues to shine.

At the heart of the surge is Nick Kurtz, who’s fast becoming the new frontrunner for AL Rookie of the Year, overtaking teammate Jacob Wilson thanks to a dominant series in Houston.

Kurtz Ignites A’s Sweep with Historic Power Display

Kurtz, just 22, went an astonishing 11-for-15 with nine RBIs in the series before sitting out Sunday’s finale with a tired lower body. He etched his name into the record books Friday by going 6-for-6 with four homers, eight RBIs, and 19 total bases — one of the best single-game performances in MLB history.

The slugging first baseman now sports a .309 average, 23 home runs, and a .683 slugging percentage across 67 major league games. His ascent from Triple-A Las Vegas to the big stage has been a revelation for a team eager to build a competitive core. Follow his progression and the rest of the A’s roster on the official MLB teams page.

While Kurtz soars, Wilson is battling a cold stretch, going just 4-for-38 in recent outings. He missed part of the Houston series with a lingering hand injury and remains questionable for Monday.

Cal Raleigh Keeps Mariners in Playoff Picture

The Mariners arrive tied for second in the AL West and locked in a wild-card race. Leading the charge is Cal Raleigh, who made history by becoming the first catcher and switch-hitter in league history to hit 40 homers before August.

Raleigh homered in the last two games of Seattle’s series in Anaheim and will look to stay hot in Sacramento. For updated odds and player prop performance, check the latest MLB scores and odds page.

Key Pitching Matchup: Castillo vs Sears

Monday’s opener features Luis Castillo (7-6, 3.30 ERA) for the Mariners squaring off against JP Sears (7-8, 4.98 ERA) of the Athletics.

Castillo last faced Oakland on March 28, allowing two runs in five innings. He owns a 3.28 ERA across eight career starts against the A’s. On the flip side, Sears has held the Mariners in check historically, posting a 2.67 ERA over 10 appearances.
