Nats to stick with Roark over Strasburg for G4

The Nationals are sticking with Tanner Roark as their starter for Game 4 of the National League Division Series, presented by T-Mobile, against the Cubs even after Tuesday’s game was postponed due to rain and rescheduled for Wednesday. That extra day meant Washington could have started Stephen Strasburg on normal rest with its season on the line as the Nats trail the NLDS two games to one.
