The Expos' first manager was Gene Mauch, who managed for six seasons.[3]Felipe Alou is the franchise's all-time leader in regular season games managed (1,408) and regular season game wins (691). Jim Fanning is the only Expos manager to have gone into the post-season. Buck Rodgers and Alou are the only managers to have won the NLManager of the Year Award with the Expos, in 1987 and 1994 respectively.[4]Karl Kuehl, Jim Fanning, and Tom Runnells have all spent their entire MLB managing careers with the Expos/Nationals.[5][6][7] After Manny Acta was fired during the 2009 season, Jim Riggleman, the bench coach, was named interim manager to replace him, and was promoted to the position full-time for the 2010 season.[8] After Riggleman resigned during the 2011 season and John McLaren ran the team for three games as an interim manager, the team hired veteran manager Davey Johnson, who had previously served as an advisor to Rizzo. Johnson led the team to the 2012National League East title and the franchise's first playoff berth since moving to Washington and was 2012's NL Manager of the Year, but the team did not advance past the 2012 National League Division Series. Johnson retired after the 2013 season. Matt Williams took over in 2014, leading the team to another National League East title that season, and was 2014 NL Manager of the Year, but the team did not advance past the 2014 NLDS, and Williams was fired after an unsuccessful second year in 2015. Dusty Baker managed the team in 2016 and 2017, leading Washington to consecutive National League East titles, but the team did not advance beyond the NLDS in either season and Baker's contract was not renewed after the 2017 season. The Nationals hired Dave Martinez in October 2017 to take the helm in 2018; along with leading the team to its first World Series championship, Martinez has the most victories as a manager since the team moved to Washington.
