Hansen's career was hampered throughout and was eventually cut short by chronic back ailments and other injuries. Despite being a tall shortstop at 6 ft 3 in (1.91 m), 190 lb (86 kg), Hansen was fluid and smooth in the field. He was a competent hitter as well.
A case of sciatica forced him to miss the entire 1957 season, costing him his first chance to make the Orioles.[1] His major-league debut came in a 6–1 win over the Washington Senators in the 1958 season opener at Memorial Stadium on April 15.[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 led AL shortstops in double plays in 1961, hitting 12 home runs with 51 RBI in 155 games. In the fall of 1961, Hansen was recalled for military service.[6] Before the 1963 season, he was sent to the White Sox along with knuckleballerHoyt Wilhelm in the same trade that brought Luis Aparicio to the Orioles.[7]
With Chicago, Hansen led the AL twice more in double plays and four times in assists. During a doubleheader in 1965, he tied an AL record with 18 total chances in the first game and added 10 more in the second for a total of 28, to set a major league record for a doubleheader.
In 1964, Hansen posted career-highs in batting average (.261), runs (85), hits (160) and doubles (25), and belted 20 home runs with 68 RBI. In 1965 he led the league with 162 games played, but was out again with back problems in 1966, appearing in only 23 games. He underwent surgery for a ruptured spinal disc and returned in 1967, playing in 157 games.
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.[8] On July 30, while playing for the Senators in a game against the Cleveland Indians, Hansen turned the eighth unassisted triple play in major league history and the first in 41 years. In the bottom of the first inning, Hansen caught a line drive off the bat of Joe Azcue, touched second base to put out Dave Nelson, then tagged Russ Snyder coming from first base.[9] In the at-bats following the triple play, Hansen struck out six consecutive times – four times on July 30,[10] and twice more on July 31.[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. Curiously, Hansen was exchanged for Cullen, the first time in MLB history where two players were traded for each other twice in the same season.[9]
Again with the White Sox, Hansen served in a backup role for the rest of the 1968 season, and again in 1969. He then finished his career as a utility infielder with the New York Yankees and the Kansas City Royals. After retiring as a player, he stayed involved with baseball, serving at different times as a major league coach and minor league manager, and also as an advance scout for the Yankees and then the Philadelphia Phillies, until retiring in 2010.[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.[1]
