Key stat I: 14, consecutive Wimbledon men's titles won by Federer, Djokovic, Nadal or Murray.
Key stat II: 2, past Wimbledon champions in the women's field, Venus Williams and Petra Kvitova.
Great eight? With Murray off form this season, Federer is a popular pick to win Wimbledon for what would be a record eighth time.
Rafa's return: Nadal is back at Wimbledon after being out last year with an injured left wrist.
Paris to London: After coming out of nowhere to win the French Open women's title, Jelena Ostapenko is seeded 13th. Grass is her favorite surface; she was the junior champion at Wimbledon in 2014.
