Strasburg has been scratched from his start Wednesday due to illness.

It's unclear what illness has hit the right-hander, but it appears to have Strasburg feeling bad enough that he'll take the night off. It's also unknown whether Strasburg will simply pitch Thursday or if he'll wait until his next scheduled start, but that should become clearer as the day goes on and once we know exactly what ailment has hit him. Tanner Roark will start in his place Wednesday.
