SAN DIEGO (Interstat) — Xander Bogaerts drove in three runs with three hits and Michael King delivered six strong innings as the surging San Diego Padres defeated the Seattle Mariners 4-1 on Tuesday night at PETCO Park.

The victory was the sixth straight and ninth in 10 games for the Padres, who improved to 11-6. The Mariners, coming off a series win over Houston, fell to 8-10.

A crowd of 38,152 watched the Padres claim the opener of the three-game Vedder Cup series, an annual interleague competition named for Pearl Jam frontman Eddie Vedder, who has ties to both cities. The trophy is a Fender Telecaster guitar signed by Vedder.

The most important sequence of the game unfolded in the bottom of the third inning, erasing Seattle’s early lead and setting the tone for the Padres’ control of the contest. Trailing 1-0, Ramón Laureano led off the frame with a triple off Mariners starter Bryan Woo. Fernando Tatis Jr. followed with an RBI single to tie the game. After Jackson Merrill singled, moving Tatis to third, and a pop out, Bogaerts stepped in. The shortstop lined a two-run single to center, scoring both Tatis and Merrill to give San Diego a 3-1 advantage it would not relinquish.

That offensive outburst was more than enough support for King (2-1), who earned the win. The right-hander allowed one run on four hits over six innings, walking one and striking out five. He efficiently navigated traffic, aided by two double plays turned behind him. King has now logged quality starts in two of his last three outings.

Seattle’s lone run came in the second inning. Randy Arozarena and Luke Raley opened the frame with singles, and after a hit-by-pitch loaded the bases, Dominic Canzone lifted a sacrifice fly to center to plate Arozarena. King limited the damage by striking out Cole Young to end the threat.

Woo (0-2) took the loss for Seattle despite a solid effort. He worked seven innings, yielding three runs on eight hits with three strikeouts. The Mariners’ offense, however, managed only four hits total and grounded into two critical double plays to stifle potential rallies.

The Padres bullpen preserved the lead with three perfect innings. Adrian Morejon struck out one in the seventh, Jason Adam needed just eight pitches in the eighth, and Mason Miller closed it in the ninth for his fifth save. Miller’s scoreless innings streak now stands at 29 2/3, the longest active run in the majors and the third-longest in Padres history. He has struck out 20 of the 27 batters he has faced this season.

San Diego added an insurance run in the eighth off Seattle reliever Casey Legumina. Merrill led off with a double, advanced to third on a flyout, and scored on Bogaerts’ third hit of the night, a single to right.

The Mariners never seriously threatened after the third. Their best chance came in that inning when they put runners on the corners with one out, but King struck out Arozarena to end the frame. Seattle’s 3-4-5 hitters — Julio Rodríguez, Josh Naylor and Arozarena — combined to go 1-for-11 with a walk and four strikeouts.

The game time was 2 hours, 19 minutes.

The teams continue the series Wednesday night at PETCO Park. The Mariners will look to even the Vedder Cup series before it shifts to Seattle later in the season. The Padres, riding their winning streak, will aim to secure the series victory ahead of a weekend Freeway Series against the Los Angeles Angels.
