Marcum allowed a leadoff single in the first to Andrelton Simmons, quickly erased on a hard-hit double play, and didn't permit another hit until the sixth. The only baserunner the Braves managed during that stretch came when Uggla was hit by a pitch in the second.
After that, Marcum retired 13 straight batters before Simmons reached down and floated a flare over shortstop with two outs in the sixth. Hustling all the way out of the box, Simmons legged it out for a double. He was stranded when Jason Heyward took a called third strike.
Relying on an effective slider and changeup to go with his 85 mph fastball, Marcum cooled off the Atlanta bats with finesse. He struck out slumping B.J. Upton looking to end the seventh, surpassing his previous career high of 11 strikeouts set on June 16, 2007, with Toronto against Washington.
It was the right-hander's fourth career double-digit strikeout game and first since July 20, 2010, with Toronto against Cleveland.
"You don't have to light up the radar gun to be successful," Uggla said. "Marcum really knows how to pitch — every aspect of the word pitching. He's very patient. He knows his strengths, knows his weaknesses, and he had just unbelievable command. Not just his fastball, but of everything. He knows what he wants to do with every pitch. So he was good tonight, man. He really kept us off balance."
Freddie Freeman fanned all four times up for the Braves, who lead the NL by a wide margin with 448 strikeouts. Upton and Heyward each whiffed three times.
