Serena Williams defeated fellow American, Alison Riske, despite a sluggish performance to qualify for the semi-finals at Wimbledon.
Williams beat Riske 6-4 4-6 6-3, to keep hopes of her eight Wimbledon title and first Grand Slam title since January 2017, alive.

Williams was broken early in the opening set, with Riske not allowing her to settle but she broke back to level the scores at 3-3.
Riske immediately broke Williams again, only to lose her own serve once more, before Williams went on to break her decisively on her second set point to take the opener 6-4.
The second set, however, proved the polar opposite, staying on serve until Riske broke her opponent to go 5-4 up before serving out to love to seal a set in which Williams made 10 unforced errors.
But, having been broken immediately in the deciding set, Williams responded by winning three consecutive games, only to lose her serve once again.
