Phoenix, AZ (Sports Network) - Adam LaRoche had three hits and two runs scored, helping Barry Enright win his third game of the season, as Arizona doubled up Washington, 8-4, in the finale of a four-game set at Chase Field.
Enright (3-2) gave up two runs on six hits with three strikeouts and two walks over six frames. Kelly Johnsonwent 3-for-4 and Rusty Ryal had two hits, two runs scored and an RBI for Arizona, winners in two of three games.
Ross Detwiler (0-2) took the loss, yielding seven runs -- four earned -- on nine hits with five strikeouts and two walks over four-plus frames. Ryan Zimmerman hit a pair of homers, the fifth time he has accomplished the feat this season, for the Nationals, losers in two of three.
"We don't make plays when he (Detwiler) pitches," said Nationals manager Jim Riggleman. "Terrible performance by our club."
Arizona scored a pair of runs in the second as LaRoche doubled and scored when Ryal reached on a fielding error by Adam Dunn at first. Bobby Crosby then hit a two-bagger to right scoring Ryal for a 2-0 edge.
Adam Kennedy's home run in the third cut the deficit in half, but Arizona's offense went back on the attack in the fourth. Ryal singled and another Nats miscue, a fielding error by Zimmerman, on a grounder by Crosby left both runners safe. Stephen Drew sliced a run-scoring single to center and John Hester moved up both runners with a grounder to second.
Crosby was caught stealing home, but Drew scored the inning's second run on a single off the bat of Enright.
Zimmerman atoned for his miscue with a solo shot to right in the fifth, but the Diamondbacks kept the pressure on with a three-spot in the home half. Johnson tripled down the line in right and scored on Justin Upton's single. He moved to second on LaRoche's base hit then Ryal's single through the hole and into right plated Upton. Hester walked to load the bases and a wild pitch on a strikeout of Enright allowed LaRoche to score for a 7-2 lead.
Roger Bernadina and Zimmerman hit solo home runs in the seventh and eighth frames, respectively, to cut the deficit to 7-4, but the Diamondbacks added an insurance run on Upton's sacrifice fly in the eighth.
Detwiler has a 1-8 all-time record in the majors over 19 total appearances (17 starts) ... Enright has yielded two runs or less in all but one of his seven starts ... LaRoche now has 24 doubles on the season ... Zimmerman has nine career multi-homer games.
