The Washington Nationals will decline first baseman Ryan Zimmerman's $18 million option for 2020, according to Jon Heyman of MLB Network.
Heyman noted the club is interested in bringing the longtime star back at a lower salary.
The 35-year-old has played his entire 15-year career in Washington after the Nats drafted him fourth overall out of the University of Virginia in 2005.
The two-time All-Star has smacked 270 home runs, knocked in 1,015 runners and posted a .818 OPS for his career. He has won two Silver Slugger Awards, finished among the top 25 in the NL MVP voting four times, won a Gold Glove and finished second in the NL Rookie of the Year race.
