The 24-year-old right-hander yielded just two hits over six scoreless innings, and the Atlanta Braves got home runs from Martin Prado, Freddie Freeman, Dan Uggla and pinch-hitter Eric Hinske to rout the Dodgers 10-1 on Tuesday night.
Beachy (1-1) struck out seven and walked two. He came in with a 5.19 ERA over his three previous outings this season, including a 6-5 loss on Thursday against Florida at Turner Field in which he was charged with five runs and four walks in 5q innings.
"It's not a bad place to get the first win. I don't think any place would have been a bad place for that, but I think it's pretty cool that it happened here," said Beachy, who struck out the side in the fourth. "It took a lot longer than I had hoped to get it, but it feels good. I commanded the fastball tonight, and that was key."
The Dodgers trimmed Atlanta's lead to 2-1 in the seventh against Scott Linebrink when Juan Uribe led off with a scratch single off Linebrink's glove and scored from third when third baseman Chipper Jones robbed rookie Jerry Sands of a possible double down the line with a diving stop and threw him out by a step.
The run ended a scoreless streak of 18w innings by the Braves' bullpen. Jonny Venters replaced Linebrink, striking out pinch-hitter Marcus Thames and retiring Casey Blake on a bases-loaded grounder after a two-out walk to Jamey Carroll.
The Braves blew it open with eight runs in the ninth. Hinske batted for Venters in the ninth and deposited Kenley Jansen's 3-1 pitch into the first row of the lower seats in the right field corner for a two-run homer.
Hinske also capped the rally with an RBI single after Uggla's three-run homer off Ramon Troncoso and RBI singles by Brian McCann and Alex Gonzalez.
