The gametime temperature was 104 degrees, the hottest game in Nationals’ history, and Strasburg clearly labored. He slowly paced around the mound in between pitches. Sweat collected on his forearms and neck. His shirt and pants were soaked.

Strasburg was pulled after three innings and 67 pitches, after allowing three runs on two hits and walking four batters. He walked the game’s first two batters. In the third inning, he walked consecutive batters and then gave up two doubles, turning a Nationals 2-0 lead into a 3-2 deficit.

After batting in the top of the fourth inning, Strasburg was pulled for reliever Chien-Ming Wang. Strasburg was dizzy, breathing heavy, his blood pressure was high and struggled to talk clearly, Manager Davey Johnson said. “When he came back, he was white as a sheet,” he said.

Strasburg said he had prepared more than normal for the start, knowing it would be dangerously hot.

It matched the shortest outing of his career. The last time Strasburg completed only three innings was Sept. 11, 2011 against Houston.
