Teammate Cory Spangenberg hit two solo home runs as the Padres knocked around Nationals right-hander Doug Fister. Fister (2-2) allowed seven runs in two innings.
Tyson Ross (2-3), meanwhile, won for the first time since April 12, allowing two runs on five hits in five-plus innings with three walks and six strikeouts. His outing was interrupted after one out, when the tarp was rolled out for a rain delay that lasted one hour and 56 minutes.
"In all my days of playing and coaching, we had one instance of weather here, one instance of rain that would affect the game," Nationals manager Matt Williams said. "Hey, there is nothing we could do about it except to see if we could get the game in. Unfortunately, it didn't go our way tonight. So, we'll get back at it tomorrow."
MOMENTS THAT MATTERED Another fast start: After the delay, the Padres jumped on Fister for three runs in the bottom of the first -- all coming on Norris' home run to left field, his third of the season. The Padres have scored 30 runs in the first inning this season after scoring 62 a year ago. More >
Nats don't hit often enough: The Nationals collected eight hits, but only three after the fifth inning. Wilson Ramos had the biggest knock, a single in the fourth that scored Bryce Harper. Ramos now has a 16-game hitting streak, the longest active streak in the Majors. He is hitting .387 (24-for-62) during the streak.
Not a slap hitter: Spangenberg, the Padres' speedy leadoff hitter, didn't need his feet to make an impact. He hit his first two home runs of the season, one to right field and another to left field, an opposite-field shot. When he was drafted in the first round in 2011, his coach at Indian River State College, Mitch Markham, said Spangenberg wasn't a "punch and Judy hitter." He has four career homers. Power hitter?
"I wouldn't say that," Spangenberg said, smiling. "But I think I have it in me. When I do hit the ball well, it travels all right."
Fister gets hit hard: Fister had his worst outing of the season, pitching just two innings and allowing a season-high seven runs on eight hits, but he didn't think the rain delay was to blame.
"I can't make any excuses for what I did tonight," he said. "It's one of those nights I didn't do my job at all. I put our team in the hole. That hurts me and the team. There is no excuse." More >
SOUND SMART WITH YOUR FRIENDS
Norris, who was drafted by the Nationals in 2007, continues to torment them. In four career games against Washington, he has three home runs and 12 RBIs. He drove in a career-high six runs in a game against the Nats last season while playing for the A's.
Fister walked one batter, his first since April 27 against the Braves, a span of 19 1/3 innings.
RAIN, RAIN, GO AWAY
Ross got off to a fast start, striking out Denard Span before rain halted the game after he threw six pitches in the top of the first inning. This marked the sixth delayed game in Petco Park history -- the ballpark opened in 2004. Five of the delays were due to rain, one because of bees (yes, bees) in 2009.
WHAT'S NEXT Nationals:Jordan Zimmermann (2-2, 4.20 ERA) will take the mound on Friday night at Petco Park. The last time Zimmermann faced the Padres on the road was June 8, when he struck out 12 in a two-hit shutout. Zimmermann retired the first 16 batters he faced before Alexi Amarista singled to right field in the sixth inning.
Padres:Odrisamer Despaigne (2-1, 5.13) gets the start in the second game of the series at 7:10 p.m PT. Despaigne is filling in for No. 5 starter Brandon Morrow, who is on the disabled list with a inflammation of his right shoulder.
