Nats-Fish rained out; Gio to pitch in San Diego

Makeup date yet to be announced for game vs. Miami

WASHINGTON -- Sunday's game between the Nationals and Marlins has been postponed because of rain. The makeup date will be announced in the coming days.

Tickets for Sunday's game at Nationals Park can be exchanged at the Nationals Park Box Office for seats of equal or lesser value for the rescheduled makeup game or a regular or value game during the 2012 regular season.

For more information on exchanging tickets purchased through nationals.com or the Nationals telephone charge line, please visit nationals.com or call 888-632-NATS(6287). All rain check exchanges are subject to availability. It excludes prime or marquee games.

With the rainout, the Nationals will push left-hander Gio Gonzalez back two days and their other starters one. Gonzalez was scheduled to pitch Sunday, and after Monday's off-day, he will now throw against the Padres on Tuesday night at Petco Park. Right-hander Jordan Zimmermann is expected to pitch the next day.

Stephen Strasburg will now pitch against the Dodgers on Saturday, and he will not be matched up against ace left-hander Clayton Kershaw, who is pitching on Friday.

With Strasburg on an innings limit this season, manager Davey Johnson was asked why the young hurler is not being skipped in the rotation.

"One of the worst things you can do to any pitcher is too much time between starts," Johnson said. "Regularity is what they need. ... In this case, we keep them in line."

The Nationals ended the homestand with an 8-2 record. Overall, they entered Sunday in first place in the National League East with a 12-4 record, 1 1/2 games ahead of the Braves. But Johnson said there is still work to be done.

"We are not where we need to be," Johnson said. "We are going in the right direction. Every day, another guy gets a little bit better, offensively. We are getting contribution from a lot of people, so that's good."
