Venus Williams out of Wimbledon 2018 beaten by Kiki Bertens
Five-time Wimbledon champion Venus Williams became the eighth of the top 10 seeds to be knocked out after a third-round defeat to Kiki Bertens.
Ninth seed Williams, 38, was beaten 6-2 6-7 (4-6) 8-6 by the 26-year-old Dutchwoman on Court One.
Williams' fellow American Madison Keys lost nine consecutive games in her defeat to qualifier Evgeniya Rodina.
The 10th seed lost 7-5 5-7 6-4 in two hours 10 minutes against the Russian, who is ranked 120th in the world.
Williams made a sluggish start to the contest and her body language in the first set belied her frustration.
At 5-1 Williams, who won Wimbledon in 2000, 2001, 2005, 2007 and 2008, saved a set point on her serve to avoid being broken for a third time.
However, 20th seed Bertens remained unflustered and clinically closed out the set with an ace.
World number nine Williams eventually found some rhythm in the second set as the pair twice traded breaks - Beterns missing a chance to serve out for the match at 5-4 up.
In the tie-break that followed, Williams won two mini breaks to have a 6-2 advantage only to fluff a chance to close out the set before she eventually leveled the match.
The pair exchanged early breaks in the third set before Bertens squandered two break points in the eighth game as Williams held.
Williams saved two match break points on deuce at 7-6 down, but the pressure told and she struck a return low into the net to hand Bertens the victory in two hours and 40 minutes.
Keys, 23, had seemingly been cruising to the first set at 5-2 up only for the momentum to dramatically swing back to unheralded Russian Rodina.
The world number 11 made numerous unforced errors which allowed 29-year-old Rodina to come back into the match and take the first set.
Keys continued to struggle early in the second set as her losing streak of games continued and at 4-0 down the match appeared Rodina's for the taking.
However, the American suddenly rediscovered her mojo and produced a superb fightback to win the second set.
Rodina received lengthy treatment from the physio early in the third set and did not move around the court as freely.
Both players regularly exchanged breaks in a scrappy third set, before Rodina kept her nerve at 5-4 up to reach the fourth round of a Grand Slam for the first time in her career.
Ekaterina Makarova, who knocked out second seed Caroline Wozniacki in the third round, also progressed.
The 30-year-old Russian beatLucie Safarova of the Czech Republic 4-6 6-4 6-1 to seal her place in the last 16.
