Eight Nationals players filed for arbitration this evening, a procedural step toward determining their 2014 salaries.
Right-handers Jordan Zimmermann, Doug Fister, Drew Storen and Tyler Clippard, left-handers Ross Detwiler and Jerry Blevins, shortstop Ian Desmond and catcher Wilson Ramos all officially filed paperwork, according to the MLB Players' Association.
Those players and the Nationals must submit competing salary figures on Thursday, figures that ultimately would be presented before an arbitration panel during hearings next month.
The two sides are free to continue negotiating and agree to terms on their own at any point between now and the February hearings, and most cases are settled without ever going to arbitration.
The Nationals previously agreed to terms with two other arbitration-eligible players: Stephen Strasburg ($3.975 million) and Ross Ohlendorf ($1.25 million).
Players are eligible for arbitration when they have accrued 3 to 6 years of major-league service time, plus a handful of players with fewer experience (referred to as "Super 2" players).
