Jordan Walker's two-run homer in the fourth — 108.3 mph off the bat, 425 feet — held up until the ninth, when Nick Castellanos tied it with a two-run shot on a 3-2 sinker. Walker Buehler went six and gave up nothing else, and Ron Marinaccio added two clean behind him, and still it was not enough. The Padres left nine on base through nine innings, a number that should have cost them. Nolan Gorman hit the hardest ball of the night — 110.8 mph, a lineout — and it changed nothing, and then Manny Machado hit a fly ball to right field that changed everything.
