I'd imagine Gonzalez will report to Triple-A Syracuse, although the team has not announced Gonzalez's assignment.
Gonzalez, 35, was released by the Nats on Tuesday. He originally signed a minor league deal with the team early this month, and allowed four runs on seven hits over four Grapefruit League innings.
The veteran lefty joined the Nats on a minor league deal back in 2012, and quickly worked his way up to the big leagues, where he became a solid contributor on the Nats' National League East championship team.
With Jerry Blevins and Ross Detwiler serving as the Nats' lefties in the bullpen to begin the season, there wasn't a spot for Gonzalez. But along with Xavier Cedeno, he'll serve as left-handed relief depth that the Nats might call upon later in the season.
Here is the Nationals' lineup for today's Grapefruit League finale against the Mets:
3B Anthony Rendon
CF Denard Span
RF Jayson Werth
C Wilson Ramos
LF Bryce Harper
SS Ian Desmond
1B Adam LaRoche
2B Danny Espinosa
RHP Jordan Zimmermann
