Peavy was effective through the first five innings, allowing just two runs, including a homer to Ian Desmond in the fifth. The game unravelled for Peavy in the sixth when he gave up two-run homers to both Jayson Werth and Adam LaRoche that ultimately decided the outcome.
With temperatures in the mid-80s at the beginning of the game, Peavy admitted he labored through most of his start.
"It was hot and humid and I just ran out of gas," Peavy said. "I didn't have much there. That's a good lineup and they're going to work you. It was just a hot and humid night. I just gave up a few long balls that cost us the game."
Peavy lasted 5.1 innings, allowing six runs on nine hits with seven strikeouts and a walk. He evened his record to 1-1 with a 5.56 ERA. The White Sox managed just two runs through six innings before the bats came alive against Washington's bullpen.
White Sox manager Robin Ventura was supportive of Peavy after the game and credited Washington's lineup for being able to manufacture runs.
"He was good," Ventura said about Peavy. "Going through that lineup, they're tough and it takes a lot out of you. A lot of good at-bats. They finally got to him."
Peavy wished he could have a couple of pitches back.
"Obviously, the sixth inning got away from us," he said.
