Ty Cobb was the fastest in terms of games to reach the 3,000-hit mark, driving a single on August 19, 1921 at the age of 34.
He reached the mark in his 2,135th game. Cobb was also the youngest player to reach 1,000, 2,000 and 4,000 hits. Cobb achieved all these feats while playing in the American League.
Born in Georgia in 1886, Ty Cobb overcame family tragedy to forge one of the greatest careers in big-league baseball history. He established records with his 12 batting titles and .366 career average, but also developed a reputation for his fierce play and terrible temper. Voted into the Baseball Hall of Fame in the inaugural election of 1936, he died in 1961 in Atlanta.
In Major League Baseball, the 3,000 hit club is an informal term applied to the group of players who have made 3000 or more career base hits.
Currently, there are 30 players who have accomplished this.
