Luis Campusano and Ha-Seong Kim each belted three-run homers Sunday and the San Diego Padres scored 12 runs in the first three innings en route to a 13-4 drubbing of the visiting San Francisco Giants.

In earning a split of the four-game series, the Padres outhit San Francisco 16-5. Campusano finished with three hits and four RBIs, while Kim delivered three hits and three runs. Manny Machado doubled twice and drove in three.

The Padres wasted no time jumping on San Francisco starter Daulton Jefferies (0-1), scoring five in the first inning. A passed ball brought Xander Bogaerts home with the first run, Machado ripped an RBI double to center and Campusano sliced a three-run homer just over the right field wall.

San Diego made it 9-0 in the second. Jake Cronenworth laced an RBI double to the right field wall, and Kim capped the explosion by lining his three-run shot down the left field line.

In two innings, Jefferies allowed the nine runs, five earned, and nine hits in two innings. He walked none and fanned one.

Kai-Wei Teng relieved Jefferies in the third but couldn't avoid the Padres' onslaught. Rookie Jackson Merrill punched a double to the left field corner to score another rookie, Graham Pauley, and Machado later made it 12-0 by drilling a two-run double off the right field wall.

The Giants got on the board in the fourth via Thairo Estrada's first homer of the season, a two-run homer to left-center, against Padres starter Michael King.

In four innings, King allowed two runs and two hits and struck out six, but he also walked seven, pushing his pitch count to 88, 47 for strikes.

Reliever Pedro Avila (1-0) picked up the win after pitching three innings. He surrendered two runs in the seventh inning, both on infield groundouts.

Campusano capped the scoring in the bottom of the eighth with an RBI single to right-center that plated Kim.
