The Pittsburgh Pirates selected Washington in the 10th round of the 1997 Major League Baseball Draft out of Jones County High School.

In 2002, he was left off the Pirates' big-league roster and thus was available for selection in baseball's Rule 5 draft, where he was taken by the San Diego Padres.

Washington played in the Padres' system in 2003 and 2004, advancing to Triple-A, but did not make the big-league club and in 2004 was granted free agency.

[1] In 2008, just shy of his 30th birthday, after ten years and 3,980 at bats in the minor leagues, Washington finally made the majors when the Cardinals selected him to be on their big-league roster as a backup infielder.

At the start of the 2010 season, Washington signed with the Kansas City T-Bones of the American Association of Independent Professional Baseball, and re-signed with them for 2011.
