With his team down 2-1 to the Cubs in the National League Division Series, Nationals starter Stephen Strasburg declined the opportunity to start Game 4 because of an illness, reports USA Today's Bob Nightengale. Tanner Roark was scheduled to start against in Game 4 on Tuesday, but the game was rained out and rescheduled for Wednesday. That gave Strasburg an extra day of rest; Strasburg last pitched on Friday, so he would have been pitching on four days' rest. Nationals manager Dusty Baker announced that Roark would start on Wednesday in a press conference shortly after the game was officially postponed. Baker initially said that Strasburg threw a bullpen session on Tuesday, which would have rendered him unable to pitch on Wednesday, but the team later said Baker misspoke and that Strasburg threw the session on Monday.
