Seeded No.25 at the discretion of the All England Club, Williams showed flashes of brilliance and plenty of fight through the one hour and 28 minute match as she and Rus treated the crowd to two tense sets that culminated in a titanic final game, which she won on her sixth match point.
Sloane Stephens of the U.S. sits in her chair after losing a set to Donna Vekic of Croatia during the Womens Singles first round match at the Wimbledon Tennis Championships in London, Monday.
"Just test everyone equally", the seven-time Wimbledon champion said Sunday at a pre-tournament news conference. I expect to go out there.
Her first was at the French Open last month, where Williams had to pull out ahead of the fourth round with an arm injury, having suffered it as a result of playing singles and doubles in Paris. He is the first man in the Open era to play in the grass-court Grand Slam for a 20th straight year.
Williams has won 15 matches in a row at Wimbledon, a streak that encompasses titles in 2015 and 2016, although Williams said that hadnt occurred to her until a reporter mentioned it. "I'm completely so far away.' I guess they decided it was a missed test, which really doesn't make sense", Williams said. Just due to the numbers, it looks like I'm being pushed out. I just wasn't quite used to that level of wind.
Williams faces Tereza Smitkova or Viktoriya Tomova next.

"I am very happy to win, it was a tough match", Vekic said. I really dont like being away from her, Williams said.
In the women's draw, Serena's sister Venus overcame a slow start to claim a 6-7 (3) 6-2 6-1 win over Swede Johanna Larsson.
Wozniacki arrives at Wimbledon on the back of victory at the Nature Valley International and opened her campaign with a 6-0 6-3 demolition of Varvara Lepchenko.
She took the first set with a well-timed break at 6-5, with Rus serving to take it to a tie-break. It also is not unusual for athletes who have taken long breaks to be subject to additional testing because of natural physiological changes that might have occurred during the time off. "I also think it's healthy in a way for me to do what I need to do, be that working mum, then go back home and be the mum".
"How is it I'm getting tested five times?" "But I am a little bit shocked at how much I nearly want that pressure".
Magdalena Rybarikova was the first seed to lose on day one, the 19th ranked player beaten 7-5 6-3 by Sorana Cirstea, while 22nd seed Anastasija Sevastova was ousted 6-1 2-6 6-4 by Camila Giorgi.
