On May 23, 2026 the Athletics opened a three-game Memorial Day weekend series at Petco Park against the San Diego Padres, with Jeffrey Springs making the start for Oakland and Mason Miller facing his former team for the first time since he was traded last July.
The immediate stakes were clear: Oakland came in off a Southern California road trip in which the A's won three of four games against the Los Angeles Angels — and needed 10 innings to take each of the final two — while San Diego provided a stiff test at home. The Athletics sat at 26-24 and in first place in the AL West; the Padres were 29-20 and one-and-a-half games out in the NL West. Oakland held a one-and-a-half-game lead over the Texas Rangers.
Springs started his 11th game of the season with a 3-4 record, a 3.93 ERA, a 1.20 WHIP and 47 strikeouts in 55 innings. He took the loss in his previous outing against the San Francisco Giants despite allowing two runs, one earned, over six innings. Opposite him, Walker Buehler began for San Diego with a 3-2 record, a 5.01 ERA and 37 strikeouts in 41.1 innings; Buehler had allowed two runs on five hits over five innings in his last start against the Seattle Mariners.
The bullpen matchup and lineup choices added texture. Mason Miller — traded from Oakland last July — entered the game with a 1-1 record, a 0.79 ERA and 15 saves in 22 appearances, and had racked up 45 strikeouts in 22.2 innings pitched. Carlos Cortes remained in the leadoff spot for the Athletics; Nick Kurtz and Shea Langeliers swapped spots in the order. Henry Bolte started in center field while Lawrence Butler was on the bench.
Those roster notes underscored a season built on small margins. Oakland has been skirting tight games; the double 10-inning finishes against the Angels illustrate how often the A's have been pushed the distance. San Diego, meanwhile, arrives with a bullpen and rotation profile that has produced enough wins to keep them near the top of the NL West and to make this interleague series competitive beyond the novelty of Miller facing his old club.
The tension is immediate and specific: Springs offers stability in the rotation but has been the victim of an unlucky decision in his most recent start, taking a loss after six innings with two runs allowed, one earned. Miller's first trip back to face Oakland represents another awkward edge — a reliever with a sub-1.00 ERA and 15 saves against the team that traded him — but it is Miller's role with San Diego, not a headline grab, that could determine the late innings in any close game the weekend produces.
Beyond the box-score details, there is a track record that matters. The Padres took two of three from the Athletics in Sacramento last year, a recent memory that discounts the idea of a comfortable matchup for either side. The A's recent resilience in extra innings and their hold on first place make this series more than interleague exhibition: it is a measuring stick for Oakland's ability to protect its slim AL West advantage while playing away from the Coliseum.
What happens next is straightforward and consequential: can Springs give the A's length and quality early, and can Oakland's lineup — with Cortes atop the order and the Kurtz-Langeliers switch — manufacture enough offense before Miller or other San Diego relievers are needed? That is the single question hanging over this Athletics - Padres weekend, because it will decide whether Oakland keeps its fragile hold on the division or gives San Diego momentum after a season-opening stretch that has left both clubs within 1.5 games of their respective divisional targets.
