Ronald Lavern Hansen (born April 5, 1938) is an American former shortstop in Major League Baseball who played for the Baltimore Orioles (1958–1962), Chicago White Sox (1963–1967, 1968–1969), Washington Senators (1968), New York Yankees (1970–1971) and Kansas City Royals (1972).

[2] His first hit in the majors was a single to center field off Pedro Ramos in the sixth inning of another season-opening victory over the Senators in the same ballpark two years later on April 19, 1960.

[3] Between the two milestones, he appeared in only 14 games in the majors and established an Orioles record among position players by going hitless in his first 25 at-bats to begin his career with the ballclub.

[4][5] Hansen surpassed all expectations by turning in a solid, injury-free 1960 season, filling the Orioles urgent need for a quality shortstop.

In February 1968, Hansen was sent to the Senators as part of a six-player trade, with infielder Tim Cullen being one of the players received by the White Sox.

[11] On August 1 he hit a grand slam home run,[12] and the following day, batting .185,[13] was traded back to the White Sox.

[1] During his work with the Phillies, Hansen was in the stands at Progressive Field in Cleveland on May 12, 2008, when Indians second baseman Asdrúbal Cabrera made his unassisted triple play, against the Toronto Blue Jays.
