Sherrard Alexander Robertson (January 1, 1919 – October 23, 1970) was a Canadian-American utility player, front office executive, and coach in Major League Baseball (MLB).

[1][2] The nephew of Baseball Hall of Fame pitcher, manager and club owner Clark Griffith, Robertson was part of an extended family that operated the Washington Senators/Minnesota Twins franchise of the American League for 72 years.

In his dozen years in that role, the organization produced four Hall of Famers: second baseman and seven-time batting champion Rod Carew, outfielder and three-time batting champ Tony Oliva, southpaw pitcher Jim Kaat, who won 283 games over his 25-year MLB career, and right-hander Bert Blyleven, whose 287-win, 22-year career (1970–90, 1992) began in Robertson's minor league system in 1969.

In 1970, Robertson returned to uniform as bench coach for Twins' manager Bill Rigney as the team won the American League West Division championship.

His throw to first baseman Mickey Vernon was high, and went into the front row of the stands, where it struck 32-year-old Clarence Stagemyer, who, after shaking his head a few times, said he was all right.

On October 25, 1944, he reported aboard the Naval Air Station Kaneohe Bay, Hawaii as a Specialist (Physical Training Instructor) 1st Class Petty Officer.
