Washington Nationals pitcher Stephen Strasburg left his start Saturday after just three innings because of heat-related issues.
Laboring in 104-degree conditions, Strasburg didn't return to begin the fourth against Atlanta, tying for the shortest outing of his 33-start career.
Chien-Ming Wang replaced Strasburg, who allowed two hits, three runs and four walks. Making 36 of his 67 pitches for strikes, Strasburg struck out four to reach 122, most in the majors.
Strasburg took extra time between pitches and walked slowly between innings. He left trailing 3-2 after the Braves' three-run third.
His previous shortest outing was Sept. 11, 2011, when he received no-decision at home against Houston - the second start he made after returning from elbow surgery on Sept. 3, 2010.
