Draft and minor leagues

Williams was drafted by the San Francisco Giants in the first round (as the third pick) of the 1986 Major League Baseball draft.

San Francisco Giants (1987–1996)

Williams began his major league career in 1987 primarily as a shortstop for the Giants while playing some games at third base also. He played both shortstop and third base until the 1990 season when he became the starting third baseman for the Giants and went on to lead the National League in RBI with 122 while making the National League All-Star team. Despite suffering from several leg injuries and some lower-back ailments, Williams was an excellent fielder at third base, and a dangerous and productive hitter. As a third baseman, Williams had good reflexes and excellent hands, with a quick release and strong, accurate arm. During his career, he earned four Gold Glove Awards, all between 1991 and 1997.

A hitter with exceptional power, six times he hit more than 30 home runs in a season as a Giant, with more than 90 RBI. His best season was 1994 when he hit a National League-best 43 home runs and had 96 RBI in only 112 games as the Major League Baseball season was shortened by nearly one-third because of a season-ending strike by Major League baseball players. He was on pace to challenge the single season home run record of 61, at the time held by Roger Maris, with his 43 home runs in 115 games, projecting to 60.6 home runs at season's end. Williams finished second in the voting for the National League Most Valuable Player Award that year behind first baseman Jeff Bagwell of the Houston Astros.

Cleveland Indians (1997)

Williams was traded to Cleveland after the 1996 season in a six-player trade that worked out for both teams; the Giants received future National League MVP Jeff Kent in the deal.

In 1997, while Williams' streak of three straight All-Star selections ended, he exceeded 30 home runs and 100 RBI and won a Gold Glove and Silver Slugger, all for the first time since 1994. He also helped lead Cleveland to its second American League pennant in three years, although the Indians lost the World Series in seven games to the Florida Marlins. After his divorce from his first wife Tracie, Williams requested and was granted a trade to the Arizona Diamondbacks to be closer to his children.^[4]

Arizona Diamondbacks (1998–2003)

Williams was an original member of the Arizona Diamondbacks from the club's inaugural season in 1998.^[5] He shares the Diamondbacks record for the most RBI in one season with a total of 142 during 1999; the record was tied by Luis Gonzalez in 2001, but has never been exceeded.^[6]

Williams was a partial owner of the Diamondbacks, and carried the title of "Special Assistant to the General Partner". Williams occasionally also served as color commentator during Diamondbacks radio and television broadcasts,^[7] and also assisted in coaching and with player personnel matters.^{[citation needed]}

Williams was hired in November 2009 by the Diamondbacks to be the first base coach for 2010. Williams moved from first base coach to third base coach for the 2011 season, while working under first-year manager Kirk Gibson.^{[citation needed]}

Washington Nationals (2014–2015)

On October 31, 2013, the Washington Nationals announced that they had hired Williams to replace Davey Johnson as their manager for the 2014 season.^[8] Prior to the 2015 season, the Nationals exercised an option to extend Williams through the 2016 season.^[9] Williams managed the Nationals to a NL East division title and the playoffs,^[10] but lost the NLDS to the San Francisco Giants. Williams was named the 2014 National League Manager of the Year.

On October 5, 2015, the Nationals terminated Williams after a disappointing season where they were World Series favorites and failed to make the postseason.^[11] He finished with a record of 179 wins and 145 losses.^[12]

Kia Tigers (2020–2021)

Williams joined the Kia Tigers of the KBO League, becoming their first American-born manager before the 2020 season.^[13] On November 5, 2021, it was announced that Williams would not be returning to the team in 2022 after the club finished in ninth place with a 58–75 record in 2021.^[14]
