Prado had last hit a home run in the Braves' 10-5 victory on June 20 against Phil Hughes and the Yankees.
Prado has six home runs this season and is on pace to hit eight, which would be his lowest total since becoming a regular fixture in the Braves lineup in 2009.
Prado said he's not concerned with hitting home runs and believes he's been too worried about them in the past.
"I was concentrating so much on hitting homers last year that I was forgetting what brought me here," Prado said. "What brought me here was hitting the ball the other way, moving the runner, doing the little things in baseball. That, for me, is more important than hitting homers."
Prado has done the little things well this year and is hitting .299 with a .359 on-base percentage, despite a second-half slump. He is hitting .240 since the All-Star break, down from his .321 first-half mark.
