Ozzie Guillén, manager of the 2005 World Series Champion Chicago White Sox, has worn the number throughout his baseball career. Alex Rodriguez began wearing it upon joining the New York Yankees (three, the number he had previously worn, is retired by the Bronx Bombers to honor Babe Ruth). Dan Marino, an American football player known for passing the 3rd most yards in NFL history, wore the number 13. Basketball great Wilt Chamberlain wore the number 13 on his jersey throughout his NBA career. Also, FIBA rules require a player to wear the number in international competitions (only numbers from 4 to 15 could be worn, and as there are 12 players, one must wear 13); Chris Mullin, who wore No. 20 in college and No. 17 in the NBA, wore No. 13 for both (1984 and 1992) of his Olympic appearances. Shaquille O'Neal wore No. 13 in 1996; Tim Duncan wore No. 13 in 2004. Steve Nash is currently wearing it for the Phoenix Suns. Yao Ming wore it in the 2008 Olympics in Beijing. Mats Sundin, Pavel Datsyuk, Bill Guerin, and Michael Cammalleri wear 13 in the NHL.

In association football, both Gerd Müller and Michael Ballack have favoured the number 13, among others.[Citation needed]

In Italy, 13 is also considered to be a lucky number, although in Campania the expression 'tredici' (meaning 13) is said when one considers their luck to have turned for the worse.

Some people even have 13 tattooed onto them to represent the lucky number.
