Washington starting pitcher Stephen Strasburg (6-1) yielded only four hits, including one for extra bases, over seven dazzling innings during the Nationals' 2-0 victory over Atlanta on Saturday. Strasburg struck out nine batters, walked none and threw 90 pitches (59 strikes) to lower his ERA to 2.35 on the season. Twice he gave up singles and then induced double-play grounders. The right-hander allowed multiple baserunners just once -- in the third inning when Jose Constanza doubled and Michael Bourn singled -- but he did not surrender a run. "He was electric. He's always electric, but today he was hitting his spots, had his curveball going, his changeup was nasty," Atlanta's Dan Uggla said.
