Nationals' Patrick Corbin: Start moved up

Corbin is listed as the Nationals' probable pitcher for Sunday's game against the Mariners, Bobby Blanco of MASNSports.com reports.

Corbin's next start will come five days after he allowed eight runs against the Twins on Tuesday, pushing Mitchell Parker to Monday in order to give the young southpaw an extra day of rest. Corbin has been erratic this season, yielding five or more runs four times but surrendering fewer than three runs on three occasions. He owns a 6.29 ERA overall.
