DENVER — Nolan Arenado and Trevor Story continued their home-run duel Sunday as the Colorado Rockies walloped the Atlanta Braves 7-2 to sweep their four-game series.
Arenado hit a three-run homer, his 25th of the season, in the first when the Rockies jumped on Braves starter Tyrell Jenkins for four runs.
Story belted his 27th homer in the fourth, a two-run shot that made it 7-0. It was Story’s fourth homer in three games and fifth in his past seven. During that span, Story has driven in 12 runs, giving him 69 RBIs for the season.
Story leads the National League in home runs. Arenado, who topped the NL last year with 42 homers, is tied for second with Kris Bryant of the Chicago Cubs.
DJ LeMahieu, who had three hits, led off the fourth with his career-high-tying sixth home run, matching his 2015 total. LeMahieu had gone 75 at-bats without a homer since he last connected June 25 against Arizona.
Rockies starter Tyler Chatwood had a bizarre outing. He allowed one hit — a first-inning single — in five scoreless innings with a career-high eight walks and six strikeouts. Chatwood (9-6) threw just 51 strikes among his 97 pitches but won for the first time in five starts since June 11.
Daryl Kile is the only other Rockies pitcher to throw five or more scoreless innings with eight or more walks. On May 30, 1999, at Philadelphia, Kile walked eight in 7 2/3 innings but allowed three hits.
The sweep of the Braves enabled the Rockies finish their homestand 5-2. They are 7-3 in the second half and have won 10 of their past 16 games.
The Braves were swept in a four-game series for the second time this year, the other coming April 11-14 at Washington. The Braves have lost five straight games and are 2-8 since the All-Star break.
The Rockies have won 10 straight games from the Braves at Coors Field, matching their record win streak there against any team. Colorado also won 10 straight games at Coors Field against Cincinnati from Aug. 23, 2008-Sept. 9, 2010.
The Rockies have won 14 of their past 16 games overall against Atlanta and swept the Braves in a four-game series for the second time in two seasons.
Arenado homered for the second time in three games after Charlie Blackmon led off the bottom of the first inning with a single and LeMahieu walked. Story doubled with one out and scored on Nick Hundley’s two-out single. Jenkins walked Chatwood to load the bases but struck out Blackmon to end a 37-pitch inning that included just 19 strikes.
Chatwood gave up two walks and a single in the first but escaped unscathed in a 21-pitch first that saw him throw more balls (11) than strikes (10). Jace Peterson was caught stealing second after opening the game with a walk. Chatwood then issued another walk and Freddie Freeman’s single but struck out Nick Markakis and got Jeff Francoeur to ground out.
Chatwood issued two more walks in the second, but sandwiched between them was a hit-robbing catch by shortstop Story of A.J. Pierzynski’s flare to short center. Chatwood then struck out Jenkins and Peterson to end the inning.
His previous career high in walks was six — a mark he tied in the fourth inning — on Sept. 13, 2013, at Arizona.
In his third career start, Jenkins (0-2) allowed eight hits, including six for extra bases, and seven runs with five walks and two strikeouts in 3 1/3 innings, an 87-pitch outing that included 45 strikes.
The Braves scored two runs in the seventh off Gonzalez Germen. Freeman doubled home the first run and took third when right fielder Carlos Gonzalez’s throw home took a high bounce, enabling Freeman to take third. He scored on a ground out.
NOTES: SS Trevor Story, 23, on Saturday became the youngest player to have a 4-for-4 or better game with two homers and one stolen base since 21-year-old Joe Morgan went 6-for-6 in 1965, according to the Elias Sports Bureau. …Braves RHP Julio Teheran felt fine after playing catch and expects to make his next scheduled start Thursday against Philadelphia. He came out of his start Friday in the fifth inning with right lat tightness. …Beginning Monday, the Rockies play 29 of their next 35 games against teams that are at least seven games above .500. …Rockies LHP Chris Rusin (left shoulder strain) was scheduled to make his third rehab start Sunday night for Triple-A Albuquerque. He was scheduled to throw five innings and/or 75 pitches. He will join the Rockies in Baltimore, where they begin a series Monday, and be re-evaluated.
