Ludwick, who entered Wednesday hitting .209 with four home runs and 11 RBIs, is hitting .324 with three home runs over his last eight games.
"He's swinging better," Padres manager Bud Black said. "And we're seeing more hard contact. He's confident right now."
Ludwick had hit safely in each of his last six games against the Braves since April 26, 2010, and is a career .292 hitter against the Braves in 96 at-bats.
