text:  In tennis, the defending Wimbledon men's champion Carlos Alcaraz is about to face Novak Djokovic in the singles final. It's a rematch of last year's final when the Spaniard, who's now 21, defeated Djokovic in five sets. If he wins, Djokovic, who's 37 and recently had knee surgery, will equal Roger Federer's record of eight men's Wimbledon titles.
