"Chatwood threw well and has all year," said Dodgers manager Dave Roberts.
Howie Kendrick's second-inning single was the only hit for the Dodgers, who were one-hit by the Cubs one week earlier. Chatwood bounced back from a second inning where his command had loosened, walking the leadoff hitter then allowing his only run of the night.
"It was a bit of a grind on my command early, but then I was able to settle in and the offense put some runs on the board," Chatwood said. "I was able to go right at guys and some two-seamers were working to get ground balls."
The Rockies struck in the top of the second inning on Gerardo Parra's fifth home run, but the Dodgers answered in the bottom of the frame with an Adrian Gonzalez walk, Kendrick's single and an RBI fielder's choice grounder by Kiké Hernandez. Mark Reynolds doubled and was singled home by Nick Hundley to break the tie in the fifth inning. Arenado singled in the other Rockies run in the sixth inning.
MOMENTS THAT MATTERED Sixteen for Story: Story broke the game open in the sixth inning with a three-run blast, projected by Statcast™ at 405 feet away. His 16 homers have him tied for fourth in the Major Leagues, and the only player with more in the National League is Arenado.
"I can't get too overwhelmed or emotional, but it gives you a little extra attitude up there," Story said.
Nice pickup: Dodgers reliever Casey Fien struck out one in another scoreless inning. He's retired 13 of 15 batters faced with eight strikeouts after being claimed from Minnesota on May 28.
Rejected pitch from Chatwood: Sitting at 100 pitches after eight innings, Chatwood lobbied manager Walt Weiss to keep him in to pitch a complete game, and actually got the skipper to consider it. However, Weiss decided to send out Gonzalez Germen to preserve Chatwood's arm, which underwent its second Tommy John Surgery two seasons ago.
"He was outstanding," Dodgers catcher A.J. Ellis said of Chatwood. "The guy's a bulldog, competes really hard, uses both sides of the plate. He's been a handful as long as I've been here."
SOUND SMART WITH YOUR FRIENDS The combined one-hitter is the second in Rockies' history. The first came in 2006 against the Athletics, with starter Jason Jennings, Tom Martin, and Brian Fuentes combining for the milestone.
STREAK WATCH Charlie Blackmon's single in the third inning extended his on-base streak to 32 games, a new career high and the longest active streak in the Majors.
WHAT'S NEXT Rockies:Eddie Butler will take the mound Tuesday with first pitch scheduled for 8:10 p.m. MT at Dodger Stadium. Butler will look to move on from an eight-run outing against the Reds in his last time out. He's been fine on the road, allowing a 2.66 ERA in 20 1/3 innings.
Dodgers: Starter Julio Urias gets a third shot at his first Major League win in the 7:10 p.m. PT start. The 19-year-old has a 9.39 ERA in two outings that have lasted a total of 7 2/3 innings. He was taken deep three times in his last start at Wrigley Field.
