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 #57.  30 players have donned #57 while playing in Chicago, 17 for the White Sox and 13 for the Cubs.

Acquired by the Cubs, along with Matt Clement, in the deal that sent Dontrelle Willis, among others, to the Marlins in March of 2002, Antonio Alfonseca became the closer for a miserable 2002 Cubs team, which just so happened to be my first as a season ticket holder.  The 12-fingered Alfonseca went 2-5 with a 4.00 ERA and 19 saves in his first go-around with the team.  In 2003, he lost the closer role and was not particularly effective, going 3-1 with a 5.83 ERA.  He was suspended for 5 games in September after bumping an umpire with his generous stomach.  He was perfect in the post-season, appearing in 4 games total giving up no runs in 3 1/3 innings against the Braves and the Marlins.  He became a free agent following that 2003 season.

#57 has been a mainstay of the back end of the White Sox bullpen for many years, shared amongst such luminaries as Jace Fry, Zach Putnam, Tony Pena, and Boone Logan.
