The MR on the team’s uniform is a mourning mark, a tribute to the chairman’s wife, who passed away in 2021 at the age of 85. Her name was Martyl Reinsdorf, so white letters in a black oval represent her initials. Members of the club will wear a commemorative patch until the end of the year. This woman has done a lot for athletes: she created the 2005 World Series championship rings and the 5th and 6th games of the Chicago Bulls NBA.
