Williams served as manager of the Washington Senators, from 1969–1971, then continued with the team when they became the Texas Rangers after the 1971 season. Williams's best season as a manager was 1969 when he led the expansion Senators to an 86–76 record in the team's only winning season in Washington. He was chosen "Manager of the Year" after that season. Like many great players, Williams became impatient with ordinary athletes' abilities and attitudes, particularly those of pitchers, whom he admitted he never respected. He occasionally appeared at Red Sox spring training as a guest hitting instructor. Beginning in 1961, he would spend summers at the Ted Williams Baseball Camp in Lakeville, Massachusetts, which he had established in 1958 with his friend Al Cassidy and two other business partners. For eight summers and parts of others after that, he would give hitting clinics and talk baseball at the camp. It was not uncommon to find Williams fishing in the pond at the camp. The area now is owned by the town and a few of the buildings still stand. In the main lodge one can still see memorabilia from Williams's playing days.
