SAN DIEGO -- Trouble comes in threes, as the old saying goes, and for Luis Perdomo and the Padres on Monday night, the majority of the trouble came via three doubles in one inning as the Dodgers clubbed their way to an 8-2 victory at Petco Park.
Los Angeles led off the fourth with five straight baserunners before Perdomo recorded an out. Cody Bellinger led off with a double and scored two batters later when Yasmani Grandal ripped a double of his own. Chris Taylor followed with an RBI single and Alvin Toles added a two-run two-bagger before racing home on Joc Pederson's fielder's choice grounder to cap the five-spot.
The barrage gave the Dodgers a comfy lead they wouldn't relinquish, as the Padres were held to two hits over six scoreless innings by Clayton Kershaw and dropped their 14th series opener at home this season.
"That inning was obviously the rough spot," manager Andy Green said. "I thought it got quick that inning."

Perdomo, making his second start since being recalled on July 4, nearly matched Kershaw's efficiency for the first three frames. He notched 1-2-3 first and third innings, and maneuvered through three hits and an intentional walk in a scoreless second, but his luck ran out in the fourth.
He finished having allowed six runs on 10 hits with three walks over seven innings.
"It's a little bit of a different mix than before, and there's moments where it's worked really well for him," Green said of Perdomo's adjustments. "There's a lot to like about the work he's put in. His effort's been great. He always wants to stay in. He knew what he was doing today, going seven innings for us."

After Sunday night's 16-inning affair vs. Arizona, San Diego opened this four-game series with a bullpen in dire need of rest and recovery, and Perdomo's seven innings provided just that.
"We needed that length badly, and he managed to give that to us," Green said. "When you play 16, the very next day turns out to be survival for your bullpen.
"To the outside world, that might not seem like a big deal. To those guys in that clubhouse that are exhausted from throwing that 16-inning game, that was a huge deal. His teammates will like that today."
There's room for improvement, but for a potential rotation candidate, Perdomo's newfound durability is a step in the right direction. In his four starts in April, Perdomo recorded just 14 innings. In his two starts since being recalled, he's accounted for 12 2/3.
MOMENTS THAT MATTERED
Kershaw remains unsolved: The Dodgers' ace was in usual form as he dominated the Padres once more. The Dodgers have won the last 13 games Kershaw has started against San Diego, with the left-hander going 10-0 with a 0.89 ERA in a span that began in September 2013.
"Compared to how we've seen him on video the last couple times out, I thought he was sharper," Green said. "I thought he had depth to his cutter and life to his fastball. We're still struggling to solve him."

Myers homers again:William Myers bashed his seventh homer of the season in the bottom of the ninth inning to give San Diego its first run of the game. He also became the third player in club history to hit five home runs in a three-game span, joining Nate Colbert (1972) and Brian Giles (2007).

LOCKETT'S LATE ARRIVAL
The Padres called up right-hander Walter Lockett from Triple-A El Paso before the game, but Lockett didn't land in San Diego until 8:15 p.m. PT, over an hour after first pitch. The reliever had two delayed flights and a reroute before finally touching down in San Diego. Not long after arriving at the ballpark, he notched two innings of relief.
"It was a little bit of a victory getting here today," he said. "A couple delayed flights, but I made it in time for two innings."
In his first stint back with the club since June 1, Lockett allowed two runs on four hits with one walk and two strikeouts.
"No time to think," he said. "Just get ready, let's go."
UP NEXT
It's youth vs. experience on Tuesday at Petco Park as rookie Eric Lauer gets the nod against Dodgers veteran Rich Hill at 7:10 p.m. PT. Lauer is in the midst of a seven-start streak in which he has pitched at least five innings, and he yielded just one earned run over five innings against Arizona on Thursday.
