Saturday’s Nationals-Tigers exhibition game at Nationals Park has been canceled because of rain. The teams were expected to play at 2 p.m., the final game before the Nationals open the season on Monday in New York. But because of the inclement weather in the forecast for most of the afternoon, the teams agreed to cancel the game. The Nationals believed there was an opening in the rain to start as scheduled at 2 p.m. but called it then.

Right-hander Tanner Roark, who was scheduled to start, will throw a heavier-than-normal bullpen session instead. In the event of a cancellation, Manager Matt Williams said he wanted Roark to pitch in a simulated game of sorts, so the right-hander will rest on the bench several times during his bullpen session to replicate innings of a game.

The Nationals announced that fans with tickets to Saturday’s canceled game can exchange them for any remaining “regular or value” home game for the 2014 season. Tickets cannot be exchanged for the home opener on April 4. Because Saturday is an exhibition game, it will not be made up.
