Duvall went 2-for-4 with two home runs and three RBI in Friday's 8-4 loss to the Mets.
The veteran outfielder gave Atlanta an early 2-0 lead when he took Kodai Senga (calf) deep in the second inning, before adding a solo shot in the ninth off Jake Diekman. Duvall has taken over the starting job in right field over the last month or so, but only because Atlanta hasn't found a better option -- in his last 20 games, he's slashing just .243/.282/.459 with four homers, nine RBI and a 4:22 BB:K. With Michael Harris (hamstring) due back in mid-August and the team likely to be active at the trade deadline, the clock on Duvall's starting stint could be ticking.
