The 37-year-old Williams, who is two wins away from equalling Margaret Court’s Grand Slam singles title record haul of 24, looked far from convincing as Riske pushed her the whole way over an engrossing two-hour duel.
However, Williams served it out with an ace to seal her 97th win at Wimbledon and avoid the same fate as world number one Ashleigh Barty, who Riske beat on Monday.
“It was really satisfying,” said Williams, whose clay court season was affected by a knee injury.
“I wouldn’t have won that match a couple of weeks ago.
“I’m glad that I was able to come through. She beat so many great players. She was really so close to taking the win today.”
Williams, who moved into second place overall behind Martina Navratilova’s record of 120 Wimbledon match wins, was constantly cajoling herself and letting out roars of come on during the match as her sometimes leaden-footed performance threatened to undo her.
Having sealed the match she turned to the players box where amongst others she was supported by older sister Venus and her husband, Reddit co-founder Alexis Ohanian, and yelled, pumping her fists.
“I was really pumped, it was for a place in the semis at Wimbledon — that doesn’t happen every day and it’s a long, arduous road,” said Williams.
“I just had to just button up and play hard.
“She was playing her heart out and she had nothing to lose and I realised neither did I.”
Serena set up a clash with unseeded Czech Barbora Strycova, who beat Britain’s Johanna Konta in straight sets.
