"We just got to play better. Period," Kemp said. "That's all I'm worrying about, playing better and getting wins.
"I feel if I continue to hit, we'll get something going."
Kemp, who was the designated hitter on Tuesday, went 2-for-4 with a double in an 8-3 loss to the Astros at Minute Maid Park. He scored and drove in a run in Atlanta's three-run sixth inning.
The two-time National League All-Star is hitting .364 (16-for-44) during his 10-game hitting streak, which dates to April 28. Missing eight games with a right hamstring strain, Kemp returned from the DL on April 20.
"Physically I feel great," said Kemp, who was acquired from San Diego on July 30, 2016. "I feel great at the plate, having good at-bats. Just got to keep it going. We got to continue to plug away.
"I'm feeling good at the plate but we need to do more. We haven't been winning games. ... We need to be firing on all cylinders and we haven't."
Kemp hit a career-high three home runs on April 29 at Milwaukee. Since joining the Braves, he has batted cleanup in all of his 76 starts. In Atlanta's three-run sixth, Kemp singled through the hole at second base, scoring Ender Inciarte. Kemp scored when Dansby Swanson walked with the bases loaded.
But it wasn't enough to keep the Braves from a fifth straight loss as they opened an eight-day, seven-game road trip.
"This is unacceptable, our team is too good," Kemp said. "We have good pitching and we have good hitting, we got a good bullpen. We got weapons to win games, and we got to do better."
