CINCINNATI (AP) -- Will Venable hit the first of San Diego's three solo homers on Friday night, taking advantage of Jon Moscot's shaky debut, and the Padres pulled away to a 6-2 victory over the Cincinnati Reds in a rain-delayed game.
Will Middlebrooks and Derek Norris also connected for the Padres, who matched their season high for homers. Every starter except the pitcher had a hit.
The Reds lost for the 13th time in 18 games, unable to overcome a rough first inning by another rookie starter. They've used four rookies in the rotation this season.
Moscot (0-1) was called up to fill in for the injured Raisel Iglesias. The right-hander threw 37 pitches in the first inning alone, walking three batters -- including Yonder Alonso with the bases loaded.
Tyson Ross improved to 4-0 in his career against the Reds by going five innings before heavy rain moved in.
Ross (3-5) allowed five hits, including Joey Votto's two-run single, before a delay of 69 minutes in the top of the sixth.
The Reds have scored a total of four runs off Ross over his career. They got only one hit off the bullpen after the rain delay.
San Diego's two runs in the first inning gave it 42 in the opening inning this season, the most in the National League.
Venable's fourth homer made it 3-0 in the second inning. Middlebrooks hit his eighth homer an inning later. Moscot lasted five innings, giving up four hits and three walks while throwing 83 pitches.
Morris homered in the seventh off Pedro Villarreal, who also was called up from Triple-A before the game.
TRAINER'S ROOM
Padres: Wil Myers' left wrist felt good after swinging a bat. He's been on the disabled list since May 19 with tendinitis. If he feels good after hitting again on Saturday, he'll start a minor league rehab assignment.
Reds: Iglesias had soreness in his left side following his start last Saturday and it bothered him when he tried to throw again, prompting the Reds to put him on the 15-day DL on Friday with a strained oblique.
UP NEXT
Padres: RH Andrew Cashner (2-8) is coming off his shortest outing, 4 2-3 innings of a 7-0 loss to the Mets. He leads the majors in losses.
Reds: RH Michael Lorenzen (1-1) makes his third consecutive start after two relief appearances. He's 0-0 with a 2.03 ERA in those last two starts.
