Roster reset for the record:
2 Cs - Gomes and Avila
7IF - Bell, Harrison
1, Turner, Castro, RZ, Garcia
2, and Mercer
3 OFs - Schwarber, Robles, Soto
4 Starting pitchers - Lester, Corbin, Fedde, and Ross
9 (10) RPs - Hand, Rainey, Finnegan, Suero, Clay, Voth, Miller, Espino
3, J-rod, (Harper as 27th man)
1 Harrison is the backup outfielder at all 3 positions while Stevenson is on the DL.
2 Garcia on roster with Stevenson on the 10 day IL.
3 Both Espino and Rodriguez are likely available in the bullpen. Nats have not announced their starting pitcher for Tuesday (6/20) when the 5th starter slot comes up. Could be one of Espino or Rodriguez, but Scherzer would be eligible to come off the IL. That likely would result in J-Rod being sent down.
Regarding Tuesday's starter, there's this:
RHP Max Scherzer (groin inflammation)
Expected return: Possibly Tuesday
Scherzer threw a 40-pitch bullpen session on Saturday afternoon in between doubleheader games. Following his session, he said, "All good, see you Tuesday." The Nationals will evaluate how Scherzer feels on Sunday. (Last updated: June 19)
