Fernando Tatis Jr. knocked in two runs Thursday and Walker Buehler pitched into the sixth inning for his first win with San Diego as the Padres stretched their winning streak to eight games with a 5-2 verdict over the visiting Seattle Mariners.

Buehler (1-1) took a 4-0 lead into the sixth before Seattle reached him for three consecutive hits, the last an RBI single by Cal Raleigh. The right-hander limited the Mariners to two runs on five hits with a walk and seven strikeouts in five-plus innings.

Four relievers took care of things from there with closer Mason Miller logging his sixth save by striking out the side in the ninth. That enabled San Diego to sweep the three-game series and finish a 7-0 homestand.

Seattle starter Luis Castillo (0-1) gave up seven hits and four runs (one earned) over 5 1/3 innings. He walked three and fanned three.

Castillo experienced all of his trouble in the second, when he allowed four hits and did some damage to himself. His low throw to first on Jake Cronenworth’s comebacker gave the Padres an unexpected baserunner, and as they’ve done during their winning streak, they capitalized.

Luis Campusano knocked in the first run with a single, and Ramon Laureano made it 2-0 with a groundout to first. Tatis followed by lacing a two-run single to left-center, giving San Diego all the offense it needed.

Seattle had its chance to change the game’s arc in the sixth. After chasing Buehler, the Mariners got within 4-2 when Julio Rodriguez greeted reliever Bradgley Rodriguez with an RBI single. However, Adrian Morejon rode in from the bullpen when the Mariners filled the bases with one out and quashed the threat with a strikeout of pinch hitter Connor Joe and a groundout.

The Padres tacked on an insurance run in the seventh when Manny Machado blooped a single over a drawn-in infield to score Tatis.

Machado and Miguel Andujar each collected two of San Diego’s 10 hits. Seattle got two hits apiece from Raleigh and Brendan Donovan.
