Matt Williams is a former professional baseball player who played for the San Francisco Giants, Cleveland Indians, and Arizona Diamondbacks during his career. He was born on November 28, 1965, in Bishop, California, and attended the University of Nevada, Las Vegas, where he played college baseball.

Williams was drafted by the Giants in the first round of the 1986 MLB draft and made his major league debut in 1987. He quickly established himself as a power hitter and a solid defensive third baseman, earning a reputation as one of the best players in the league. He was named to the All-Star team five times and won four Gold Glove awards for his defensive prowess.

In 1994, Williams had one of the best seasons of his career, hitting 43 home runs and driving in 96 runs in just 112 games. He was on pace to break Roger Maris' single-season home run record before the season was cut short by a players' strike. Despite the shortened season, Williams finished second in the National League MVP voting that year.

Williams played for the Giants until 1996, when he was traded to the Cleveland Indians. He spent just one season in Cleveland before being traded again, this time to the Arizona Diamondbacks. It was with the Diamondbacks that Williams had his greatest success, helping the team win the World Series in 2001. He hit three home runs in the series and was named the Most Valuable Player.

Williams retired from baseball in 2003 with a career batting average of .268, 378 home runs, and 1,218 runs batted in. After his playing career, he went on to become a coach and manager, working for several teams including the Diamondbacks, Washington Nationals, and Oakland Athletics.

In 2014, Williams was named the manager of the Nationals, but he was fired after just one season following a disappointing performance by the team. He then joined the coaching staff of the A's, where he worked until 2018.

Throughout his career, Williams was known for his powerful swing and his excellent defensive skills. He was also a respected leader in the clubhouse and was often called upon to mentor younger players. Despite some ups and downs in his managerial career, Williams remains one of the most beloved players in the history of the Giants and the Diamondbacks, and his contributions to the game of baseball will not be forgotten.
