WASHINGTON (AP) -- Right-handed starter Joe Ross was optioned to Triple-A Syracuse and right-hander Jeremy Guthrie was reassigned to minor league camp as the Washington Nationals finalized their opening-day roster.
Sunday's moves mean infielder Wilmer Difo and outfielder Michael A. Taylor made the roster.
The Nationals do not need a fifth starter right away, so by sending Ross to the minors they have a spot for an extra position player.
The initial 25-man roster includes seven relievers - three are lefties - two catchers, seven infielders and five outfielders.
Five of the players were not on the NL East champions last season: center fielder Adam Eaton, catcher Matt Wieters, first-baseman-outfielder Adam Lind, right-hander Joe Blanton and left-hander Enny Romero.
The Nationals open Monday at home against Miami.
