Historically, there have been numerous players who have hit 20 doubles and 20 home runs in a year. It is the component of triples, however, that makes the 20–20–20 club so difficult to achieve. This is because hitting triples often comes under a similar hit placement as doubles, but may require impressive speed on the part of the runner. This would pose a challenge for both a slugger, who may be slower at running the bases and have the tendency to hit line drives and fly balls out of the park for a home run, as well as a speedster, who may be more swift around the bases but may not supply much power to drive the ball far.
Due to the rare occurrence and low membership of the 20–20–20 club, Baseball Digest called it "the most exclusive club in the Majors" in 1979, when there were only four members. Of the five members eligible for the Baseball Hall of Fame, three have been elected and two were elected on the first ballot.
