Nationals pitcher Stephen Strasburg has 22 strikeouts in 12 1/3 innings, giving him a 16.06 strikeouts-per-nine-inning mark.

"I'm just trying to execute pitches," Strasburg said after his second start on Sunday. "I'm not worried about strikeouts. It's not always going to be that way. There will be nights when you rack 'em up, and nights when you have one or two. I'm just worried about making them swing the bats and put it in play."

He became just the sixth pitcher in history to strike out 20 or more batters over his first two Major League appearances, and the first in 39 years.
