Edward Trowbridge Collins Sr. (May 2, 1887 – March 25, 1951), nicknamed "Cocky", was an American professional baseball player, manager and executive. He played as a second baseman in Major League Baseball from 1906 to 1930 for the Philadelphia Athletics and Chicago White Sox. A graduate of Columbia University, Collins holds major league career records in several categories and is among the top few players in several other categories. In 1925, Collins became just the sixth person to join the 3,000 hit club – and the last for the next 17 seasons. His 47 career home runs are the fewest of any player with 3,000 hits. Collins is the only non-Yankee to win five or more World Series titles with the same club as a player. He is also the only player to have been a member of all five World Series championships won by the Athletics during the franchise's time in Philadelphia.
Collins coached and managed in the major leagues after retiring as a player. He also served as general manager of the Boston Red Sox. In 1939, Collins was inducted into the Baseball Hall of Fame.
