"My teammates have picked me up, but I'm not going to lie, I've had some low moments," Uggla said.
"They've picked me up enough. It's time for me to start picking them up."
Manager Fredi Gonzalez said the homers in back-to-back games are not the first signs of Uggla finding his swing.
"It's nice to see him hitting the ball hard," Gonzalez said. "It's not all of a sudden. There have been some signs."
The Braves moved within three games of first-place Philadelphia in the NL East after the Phillies lost to Florida 7-6 in 10 innings.

Colorado again played without outfielder Carlos Gonzalez and shortstop Troy Tulowitzki, who were held out with wrist and quadriceps injuries, respectively. Gonzalez may return to the lineup in Thursday's final game of the four-game series.
Before the game, Jones said a cortisone shot in his right knee after Sunday's game did not provide much relief for the discomfort he has felt much of the season.
He found more pain in the first inning when he fouled a ball off his right ankle and immediately fell in the batter's box. Jones slowly got up and appeared to be favoring the ankle when he ran to first base on his ground out to second.
Jones' reward for remaining in the game came in the third when his fly ball barely cleared the left-field wall for his eighth homer.
Cook struggled early in his sixth start after breaking a finger in spring training and missing the first two months of the season.
Schafer led off with a triple past Charlie Blackmon in center field. Alex Gonzalez drove in Schafer with a single to right before scoring on Brian McCann's double to center. With two outs, McCann scored on Eric Hinske's single for a 3-0 lead.
Jurrjens took a no-hitter into the seventh inning of his 4-0, one-hit shutout of Baltimore on Friday night.

Herrera moved to third on Ty Wigginton's infield hit before Seth Smith ended the inning with a fly ball to left.
Scott Linebrink struck out Wigginton with the bases loaded to end the seventh.
Cook gave up 10 hits and seven runs in five-plus innings. He was pulled after giving up singles to Hinske and Uggla in the sixth.
