WASHINGTON — The Washington Nationals have fired manager Matt Williams as well as their entire coaching staff, the club announced Monday afternoon.

First reported by The Washington Post’s James Wagner, Williams was relieved of his duties after the Nationals failed to make the postseason with an 83-79 record. They finished the season seven games behind the New York Mets in the NL East.

Williams is the former NL Manager of the Year, winning the prestigious award after leading Washington to 96 wins and a division title in 2014. They were quickly eliminated in the National League Division Series, however.

Failure to live up to expectations followed the club — the preseason World Series favorites — into 2015.

Along with Williams, the Nationals have released bench coach Randy Knorr, pitching coach Steve McCatty, hitting coach Rick Schu, third base coach Bobby Henley, first base coach Tony Tarasco, bullpen coach Matt LeCroy and defensive coordinator Mark Weidemaier.
