Page "Chicago Cubs" Paragraph 62

The Chicago Cubs retired numbers are commemorated on pinstriped flags flying from the foul poles at Wrigley Field, with the exception of Jackie Robinson, the Brooklyn Dodgers player whose number 42 was retired for all clubs.

The first retired number flag, Ernie Banks ' number 14, was raised on the left field pole, and they have alternated since then.

14, 10 and 31 ( Jenkins ) fly on the left field pole ; and 26, 23 and 31 ( Maddux ) fly on the right field pole.
