Under the watchful eye of manager Fredi Gonzalez -- who made the trip rather than stay home during a split-squad doubleheader -- Beachy twirled five shutout innings and moved his Grapefruit League ERA to 1.80 in the Braves' 2-1 loss.
Andy Dirks delivered a double to plate Brennan Boesch and Scott Sizemore off Braves reliever Arodys Vizcaino in the ninth, the first runs Vizcaino has given up in four Spring Training games.
Beachy, who has given up three runs in 10 Grapefruit League frames, needed nearly 30 pitches to get through the first inning, but seemed to go on cruise control from there. He finished with one hit and three walks while throwing 50 of his 84 pitches for strikes.
"I was really struggling to throw my off-speed [pitch] early on," Beachy said. "I was not happy about that at all. As the game went on, I started throwing some curveballs for strikes, which made my slider more effective and my fastball came down in the zone."
On the other side, Rick Porcello nearly matched him pitch for pitch. The 22-year-old right-hander gave up one run on three hits and three walks in 4 2/3 innings, and he has a 3.12 Grapefruit League ERA after his start.
Jordan Schafer led off the game with a triple, then scored on an Alex Gonzalez single to give the Braves an early lead.
