Tennis action begins at 6 a.m. ET with Djokovic, Sinner, and Swiatek all scheduled for center court appearances at Wimbledon.

If Djokovic beats his compatriot he will reach a century of victories at the All England Club, a feat only surpassed by eight-time champion Roger Federer, who won 105 times on the lawns of southwest London and Martina Navratilova, who chalked up 120 victories.
