The Nationals declined the 2011 option for Adam Kennedy, according to MLB.com's Bill Ladson (on Twitter). Washington held a $2MM option for the infielder's services with a $500K buyout.
Kennedy, 34, batted .249/.327/.327 in 389 plate appearances for Washington this year. He joins a free agent market filled with some solid regulars and others who will have to battle for playing time. Kennedy is not a ranked free agent, so the Nats have no shot at draft pick compensation.
