Mariners score another painful ending in San Diego. Seattle lost 5-2 to the Padres on April 16, 2026, with the game turning into a ninth-inning disaster that finished off a road trip sweep.
The break came on one play. Josh Naylor dropped a ball that should have started a double play, and the inning unraveled from there: one run scored right away, then two more Padres crossed to make it 4-0. By the time Seattle could answer, the damage was already heavy.
Cal Raleigh tried to keep the Mariners in it. Seattle threatened in the fourth inning after a pair of leadoff singles by Brendan Donovan and Raleigh, but both runners were stranded. In the sixth, Raleigh lined a ball to right field to score Cole Young and get Seattle on the board, and the Padres then had to replace Walker Buehler after the rally.
The game had already tilted earlier. Fernando Tatís Jr. made a shoestring catch to end the second inning, and Brendan Donovan opened the game with a walk before being picked off at first for the second out. Those missed chances mattered because the Padres kept pressing, and Seattle kept letting them off the hook.
That is what made the loss sting beyond the 5-2 score. The Mariners were swept on the road trip, and the collapse extended a rough stretch against a San Diego club that has been one of their toughest tests over the last two weeks. Seattle had chances to change the shape of the game. It did not take them.
What remains for the Mariners now is simple and uncomfortable: stop the late breakdowns before another close game turns into another loss.
