Tennis has evolved. On the evidence of one night at Wimbledon, so has Serena Williams

Serena Williams, 44, played her first competitive singles match in nearly four years on Tuesday night at Wimbledon's Centre Court, facing 20-year-old Maya Joint. The match highlighted how much elite women's tennis has changed since Williams' peak, with commentator Barry Cowan noting that world No. 51 Zeynep Sönmez was hitting the ball harder than Williams during a recent practice session. Williams showed signs of adapting to the modern game, though the match was considered an imperfect sample given her opponent's inexperience.
