Donald Ray "Spin" Williams, Jr. (born January 5, 1956, at Davenport, Iowa)[1] is an American professional baseball coach.
[2] A left-handed pitcher who stood 6 ft 3 in (1.91 m) tall and weighed 210 lb (95 kg) during his playing career, Williams attended Winona State University before signing with Pittsburgh.
He then became a coach with Pirate farm teams, and spent part of the 1993 season as manager of the Double-A Carolina Mudcats of the Southern League.
He was promoted to the staff of Pirate manager Jim Leyland in 1994 when Pittsburgh bullpen coach Terry Collins departed to become skipper of the Houston Astros.
When the Pirates turned over their coaching staff after the 2005 season, Williams was released; he joined the Nationals as a player development advisor the following spring.
