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 #4.  43 different players have donned #4 while playing in Chicago, 10 for the White Sox, who retired the number in 1975, and 33 for the Cubs.

In his first go-around with the Cubs, Glenallen Hill switched to #4 for the 1994 season.  He played in 89 games and clubbed 10 home runs while collecting 38 RBIs before the strike cancelled the remainder of the season.

On the south side, Luke Appling started wearing his familiar #4 starting in 1933, where he started a string of nine straight seasons with an average above .300.  His best season was 1936, when he batted .388, knocked in 124 runs, scored 111 times, recorded 204 hits, and had a team-record 27-game hitting streak.  He became the first American League shortstop to win a batting title and his .388 average was the highest recorded by a shortstop in the entirety of the 20th century.

In 1940, Appling hit .348 with a career-high 13 triples as the White Sox finished fourth, their best finish in his career.  Appling missed the entire 1944 season and most of the 1945 season due to military service.  He hit .309 in 149 games in 1946 in his full-time return and earned his seventh and final All-Star selection in 1947 when he hit .306, Appling hit .314 and .301 in 1948 and 1949 respectively, during his age 41 and 42 seasons.  He retired following the 1950 season and was elected to the Hall of Fame in 1964.
