Padres and Mariners meet in Spring Training Game 14 in Peoria with regular season series ahead

Spring schedule spotlights Padres-Mariners matchup in Arizona

The San Diego Padres continue their Cactus League slate Thursday, March 5, 2026, with Spring Training Game 14 against the Seattle Mariners at the Peoria Sports Complex in Peoria, Arizona. First pitch is scheduled for 12:10 p.m. Pacific time. The game is slated for Padres.TV, with radio coverage on 97.3 The Fan.

Peoria remains a familiar setting for both clubs. The Padres and Mariners have shared the Peoria complex as their primary spring home for decades, making the matchup a recurring feature of the preseason calendar and one of the more routine cross-league meetings in Arizona’s spring circuit.

What spring results do—and don’t—indicate

As with most spring training games, the immediate stakes are limited. Teams typically prioritize workload management, health evaluations, and roster decisions over in-game tactics designed to maximize a single result. Pitching usage often follows pre-set plans, while position players may be rotated to accommodate at-bats for regulars and non-roster invitees.

For the Padres and Mariners, the March 5 contest also functions as a measuring point for depth: late-inning innings are commonly assigned to relievers competing for bullpen roles and to younger players seeking to force their way into the conversation for Opening Day roster spots or early-season call-ups.

Regular-season context: a six-game series and a trophy

Beyond the preseason, San Diego and Seattle are scheduled to meet six times in the 2026 regular season, continuing MLB’s format that pairs certain American League and National League clubs as annual opponents. Those games now carry added context through the Vedder Cup, a trophy created to be awarded to the winner of the season series between the Padres and Mariners. The series has also been tied to a charitable fundraising effort supporting research into epidermolysis bullosa, a rare disorder that can cause severe skin blistering.
