Fernando Tatis Jr. and Jurickson Profar slugged back-to-back homers in the first inning Friday night as the San Diego Padres snapped a five-game losing streak with a 10-3 rout of the visiting Arizona Diamondbacks.

Tatis stretched his hitting streak to 13 games when he slugged a first-pitch sinker from Brandon Pfaadt (2-5) an estimated 415 feet to center field for his 11th homer of the year. Profar followed by lining a sweeper just inside the right field foul pole for his ninth homer of the season.

Benefitting from the early offense was Michael King (5-4), who tossed five scoreless innings to earn his second win of the year over Arizona. King allowed four hits and a walk while striking out five. He has tossed 11 scoreless innings against the Diamondbacks this season.

Pfaadt was touched for nine hits and five runs over 5 1/3 innings, walking one and fanning five. It was his second loss of the year against San Diego.

The Padres, who had scored just 11 runs in their skid, added on to their early, explosive start. Luis Campusano’s RBI single in the fourth scored Ha-Seong Kim for a 3-0 lead. Kim knocked out Pfaadt when he cracked a two-run homer off the top of the center field wall in the bottom of the sixth.

Arizona got back into the game in the seventh against reliever Wandy Peralta via back-to-back homers. Ketel Marte unloaded his 13th homer with Corbin Carroll aboard, the ball barely clearing the left field wall. It was Marte’s eighth home run of the year.

Pinch hitter Lourdes Gurriel Jr. followed by lining an 0-2 pitch into the seats in left, his ninth of the season, to cut the Diamondbacks’ deficit to 5-3.

San Diego broke it open in the eighth when Campusano delivered an RBI single and Profar followed with a three-run double to right. Donovan Solano capped the inning by delivering an RBI single to center.

Campusano finished with three of the Padres’ 14 hits.
