In placing right-handed starter Doug Fister on the 15-day disabled list on Saturday afternoon, the Nationals formally announced the opening day 25-man roster, which had no surprises. Manager Matt Williams has refused to name a starting second baseman, although the team has operated as if it will be Anthony Rendon. Both Rendon and Danny Espinosa are listed as infielders, while Ian Desmond, Adam LaRoche and Ryan Zimmerman are listed at their specific positions.

The Nationals will open the season Monday at 1 p.m. in New York against the Mets.
