Ronald Washington (born April 29, 1952 in New Orleans, Louisiana) is a former infielder in Major League Baseball and the current manager of the American League's Texas Rangers. Prior to managing the Rangers, Washington coached in the New York Mets and Oakland Athletics organizations.
Washington plays a major role in the events of the book Moneyball, a book detailing how the A's have been successful despite a small budget. Washington is shown in a positive light for the way he trained Scott Hatteberg to field first base for the first time in his career. Washington is also, however, portrayed as too old-fashioned and traditional in his unacceptance of general manager Billy Beane's sabermetric strategies.On November 6, 2006, the Texas Rangers announced that Washington had accepted their offer to manage the team
Washington replaced Buck Showalter, who was fired a month earlier after failing to lead the team to a playoff appearance in four years. Washington beat out four other candidates for the job: Rangers bench coach Don Wakamatsu, then New York Mets third base coach Manny Acta, Nippon Ham Fighters manager Trey Hillman
and former Rangers catcher John Russell
The A's also had a managerial vacancy after the firing of Ken Macha at the end of the season, but it is suspected that Washington's independence eliminated him from consideration by Beane 
At the beginning of the 2007 season, it was rumored that there was a rift between Washington and Rangers star Mark Teixeira. Asked about the rift, Washington responded,
Teixeira was traded to the Atlanta Braves in July 2007. He had been rumored to have been on the trading block before reports of tensions with Washington, as his agent, Scott Boras, had refused to negotiate a contract extension beyond the 2008 season.
Similar reports rumored tensions between Washington and catcher Gerald Laird. Questioned about the rumors, Washington conceded that the pressure he put on Laird was "a lot to put on a young kid... (But) that's what we've got. He's got to grow up fast." 
On August 6, 2007, Washington was ejected for the first time of his managerial career after arguing with umpire Bill Miller after a questionable third called strike to Michael Young, who also was ejected. The Texas Rangers exercised their option to extend Washington's contract in September of his rookie season, ensuring he would manage the team through 2009.
