For five innings, Saturday night at Petco Park looked like the kind of taut, low-scoring duel these two rivals have traded all year. Then the Dodgers' sixth inning turned it into a rout.

The inning that broke it open

With Padres starter Randy Vásquez still on the mound, Kyle Tucker launched a two-run homer to snap a four-game hitless slide, Yahoo Sports reported. The next batter, catcher Dalton Rushing — mired in a slump of his own — worked to two strikes and then drove the ball over the wall for back-to-back home runs. The blasts opened the floodgates on a nine-run inning, helped along by a pair of San Diego errors, and the Dodgers cruised to a 15-3 win.

Slumps snapped

The night was a tonic for two struggling bats. Tucker finished 3 for 5 with four runs batted in. Rushing, who had gone hitless in five straight games, celebrated his homer with teammate Alex Freeland at the plate. Mookie Betts piled on with a three-run shot — his third home run in three games — to put the result well out of reach.

Yamamoto cruises

The offense made things easy on Yoshinobu Yamamoto, who gave the Dodgers exactly what a blowout needs from its starter: six innings, two runs, and no drama. By the late innings, with the margin lopsided, both teams turned to position players to finish out on the mound — the surest sign a game is long decided.

The bigger picture

The Dodgers and Padres have spent the season trading blows atop the NL West, but a double-digit beatdown in San Diego — with Vásquez tagged for both early homers — is the sort of night that lands a psychological marker. Manager Dave Roberts, still awaiting catcher Will Smith's return from a neck injury, watched his lineup erupt for 15 runs against its fiercest rival. Heading into the summer stretch, that is about as comfortable as a contender can look.
