Grace was recalled from Triple-A Syracuse and will serve as the Nationals' 26th man for Sunday's doubleheader with the Phillies, Dan Kolko of MASN reports.
Grace will give the Nationals an extra innings eater out of the bullpen in the event that either Gio Gonzalez or Max Scherzer isn't able to work deep into his respective start Sunday. Expect Grace to return to Syracuse once the doubleheader is completed.
