In 1929, uniform numbers appeared on the back of baseball jerseys for the first time, thanks to the Indians and the Yankees. By 1937, numbers finally appeared across all uniforms, both home and away, across both major leagues. Since that time, 81 distinct numbers have been worn by members of the White Sox, while the Cubs boast 76.
Today, we continue our look at those players, picking our favorite, if not the best, player to wear each uniform number for both Chicago teams with #70. 3 players have donned #70 while playing in Chicago, all of whom suited up for the White Sox.
Aaron Bummer was selected by the White Sox in the 19th round of the 2014 draft. He made his major league debut on July 27, 2017, pitching an inning of relief against the crosstown Cubs. He wore #70 for his entire first year, before switching to his more familiar #39 in 2018.
