Manny Machado hit a tiebreaking grand slam in the fifth inning and the San Diego Padres beat the New York Mets 7-4 on Wednesday night in a matchup of postseason contenders.

With two runners aboard in the ninth, All-Star closer Robert Suarez knocked down Juan Soto's line drive with his glove and calmy threw to first base for the final out.

Soto nearly tied the score at 6 with a two-run homer off Miller in the seventh, but his opposite-field drive on a 102 mph fastball sliced foul by inches in the left-field corner. Miller then struck out Soto and Alonso on sliders to end the threat.
