The Washington Nationals have posted their lineup for today's game, per the official club account.
The release lands at a notably active moment for the roster. A day after CJ Abrams returned to the field at shortstop following a stretch that had him limited to DH duty, the lineup card carries a bit more weight than usual — his presence or absence in today's configuration is worth a look.
The surrounding context has been busy. Matt Waldron was activated and Trevor Williams designated for assignment. Luis Perales was recalled for his MLB debut with Jake Bird optioned in the same move. The organization has been reshaping its active roster in real time.
