After playing collegiate baseball at Kent State University from 1958 to 1960, and hitting.358 in his senior year, Rollins was signed for $6,000 as an undrafted free agent by the then Washington Senators prior to the start of the 1960 season and assigned to the Wilson Tobs in the class-B Carolina League. He hit into a triple play in his first professional game, which left a significant impact on his baseball career. As a result, despite the embarrassment, it was the main motivation for Rollins to become a better ballplayer. After hitting.341 in 62 games, Rollins was promoted to the single-A Charlotte Hornets in the South Atlantic League to start the 1961 season. After hitting.270 in 36 early-season games at Charlotte, he was promoted to AAA Syracuse in the International League for three games and made his major league debut on June 16 and spent the rest of the season with the Twins as a little-used bench player.
Twins career
During spring training, Rollins started in both shortstop and third base. Twins owner Calvin Griffith saw Rollins potential in third base, and recommended that Rollins should be given the job over more experienced players like Harmon Killebrew, and John Goryl. Griffith stated that it was Rollins "sincerity and steadiness" on how he handled the position that proved that he can start in the American League. Having got the job, Rollins responded by hitting.486 over the Twins' first 10 games. Playing in 159 games, Rollins finished the season hitting.298 with 16 home runs and 96 runs batted in, production that would earn him the nickname, at least among his teammates, of Pie, after Pittsburgh PiratesHall of Fame third baseman, Pie Traynor Rollins was also compared to former longtime Senators third baseman Ozzie Bluege. Rollins finished eighth in the American League MVP voting and also received the most All-Star Game votes of any American League player, starting both games that year. Rollins represented the Twins well in the games, reaching base three times in six plate appearances and scoring the AL's only run in their 3–1 loss in the July 10 game. Supporting his MVP candidacy and All-Star appearances, Rollins finished in the Top 10 in the league in singles, plate appearances, sacrifice flies, hits, at-bats, runs, on-base percentage, runs batted in, and batting average. While he finished third in assists by third basemen, his 28 errors were the most by any AL third baseman and second most in the league behind Detroit Tigers' infielder Dick McAuliffe. While Rollins' glove work would never be as bad, his errors would decrease from 28 to 8 over the next four seasons, his results at the plate would also decrease and despite an almost-as-good 1963 season despite an early-season broken jaw. On June 9, 1966, in the seventh inning of a game against the Kansas City Athletics, Rollins was one of five Twins players to hit home runs. The others were Harmon Killebrew, Don Mincher, Tony Oliva and Zoilo Versalles. These five home runs still stand as a Major League record for the most home runs hit in a single inning, and were hit off starter Catfish Hunter and relievers Paul Lindblad and John Wyatt. In that season, he was platooning at third base with Killebrew and César Tovar, among others.
Later career
Left exposed to the 1968 expansion draft, Rollins was the 26th pick of the Seattle Pilots on October 15. After backing up Tommy Harper at third base, he was released by the infant Milwaukee Brewers on May 13, 1970, after starting the season hitting.200. Rollins was immediately signed by the Cleveland Indians, for whom he would finish the season before retiring.
