Are Jan Kodeš and Nenad Zimonjić both tennis players?
Jan Kodeš Jan Kodeš (born 1 March 1946) is a right-handed Czech former tennis player who won three Grand Slam singles events in the early 1970s.
Kenneth Carlsen Kenneth Carlsen (born 17 April 1973) is a Danish former professional tennis player, who was active between 1992 and 2007. Carlsen played left-handed with a one-handed backhand. His greatest asset was his powerful serve, and his game was therefore best suited to fast surfaces (grass and hardcourt) . For most of his long career Carlsen was Denmark's best tennis player, and consistently among the few Danish players playing at the highest international level. He was awarded as best Danish "Tennis Player of the Year" seven times by the Danish Tennis Federation (first time in 1991, last time in 2005). Two times the award went to the Danish Davis Cup team, of which Kenneth Carlsen until 2003 was a central part (having a 29–13 record in singles).
