Calvin Edwin Ripken Jr., nicknamed "the Iron Man", is an American former baseball shortstop and third baseman who played his entire 21-season career in Major League Baseball (MLB) for the Baltimore Orioles (1981–2001). One of his position's most productive offensive players, Ripken compiled 3,184 hits, 431 home runs, and 1,695 runs batted in during his career, and he won two Gold Glove Awards for his defense. He was a 19-time All-Star and was twice named American League (AL) Most Valuable Player (MVP). Ripken holds the record for consecutive games played (2,632), having surpassed Lou Gehrig's streak of 2,130 that had stood for 56 years and that many deemed unbreakable. In 2007, he was elected to the National Baseball Hall of Fame in his first year of eligibility with 98.53% of votes, the sixth-highest election percentage ever.

Shortstop, abbreviated SS, is the baseball or softball fielding position between second and third base, which is considered to be among the most demanding defensive positions. Historically, the position was assigned to defensive specialists who were typically poor at batting and were often placed at the bottom of the batting order. Today, shortstops are often able to hit well and many are placed at the top of the lineup. In the numbering system used by scorers to record defensive plays, the shortstop is assigned the number 6.
