A native of Millerton, a 384-acre village in Dutchess County, New York, Collins was unique in his time in that he was focused on both his athletic skills and his education and intelligence. He graduated from Columbia University (where he was a member of Beta Theta Pi fraternity) at a time when few major league players had attended college. He started his American professional baseball career on September 17, 1906, when he signed with the Philadelphia Athletics at the age of 19. When he signed with the Philadelphia organization, Collins was still a student at Columbia.
After spending all but 14 games of the 1907 season in the minor leagues, he played in 102 games in 1908 and by 1909 was a full-time player. That season, he registered a .347 batting average and 67 steals. He would also be named the A's starting second baseman in 1909, a position he would play for the rest of his career, after seeing time at second, third, short, and the outfield the previous two seasons. In 1910, Collins stole a career-high 81 bases, the first American League player to steal 80+ bases in a season, and played on the first of his six World Series championship teams. Collins was renowned for his intelligence, confidence, batting prowess and speed. He is one of only five players to steal six bases in a game, and the only person to do so twice, with both occurrences happening within eleven days, on September 11 and September 22, 1912 respectively. He was part of the Athletics' "$100,000 infield" (and the highest-paid of the quartet) which propelled the team to four American League (AL) pennants and three World Series titles between 1910 and 1914. He earned the league's Chalmers Award (early Most Valuable Player recognition) in 1914. In 1914, the newly formed Federal League disrupted major league contract stability by luring away established stars from the AL and NL with inflated salaries. To retain Collins, Athletics manager Connie Mack offered his second baseman the longest guaranteed contract (five years) that had ever been offered to a player. Collins declined, and after the 1914 season Mack sold Collins to the White Sox for $50,000, the highest price ever paid for a player up to that point and the first of only three times that a reigning MVP was sold or traded (the others being Alex Rodriguez in 2003, and Giancarlo Stanton in 2017 both to the New York Yankees). The Sox paid Collins $15,000 for 1915, making him the third highest paid player in the league, behind Ty Cobb and Tris Speaker.
