Caitlin Clark wears the jersey number 22 because of a deeply personal family connection and basketball tradition she established during her youth. She originally chose the number 22 because her older sister wore it, and she admired her athletic journey. Furthermore, she was born on the twenty-second day of the month, making the number a recurring theme in her life. She carried number 22 throughout her historic collegiate career at the University of Iowa and into her professional career in the WNBA, turning the number into an iconic global brand.
