Serena Williams is through to the second round of Wimbledon championship after a 6-4 6-1 win over Margarita Gasparyan in Court 1.
The women top seed, who is much favoured to complete the ‘Serena Slam’- a non-calendar slam which could see her hold all Major wtitles at the same time for the second time in her career- is now tied for fifth with sister Venus Williams on the list of ladies with most career singles wins at Wimbledon with her 73rd win.
Men’s singles top seed Novak Djokovic opened his title defense with a 6-4 6-4 6-4 win over Germany’s Philipp Kohlschreiber on Centre Court.
The Serb will face either veteran Leyton Hewitt or Finland’s Jarkko Nieminen in the round of 64.
Flavia Panneta suffered the first upset of this year’s championship, as the No. 24th seed was sent packing by Zarina Dyas 6-3 2-6 6-4. Spanish ninth seed Carla Suarez Navarro followed suit, losing in straight sets to 2014 Wimbledon junior champion Jelena Ostapenko of Latvia, 6-2 6-0.
Nick Kyrgios defeated Argentina’s Diego Schwartzman 6-0 6-2 7-6 (6) to book his place in the second round.
2009 quarter-finalist Victoria Azarenka secured a routine victory over Estonia’s Anett Kontaveit.
Reigning U.S., Australian and French Open champion, Serena, was not at her best against debutant Gasparyan, but found the winning mentality when it mattered most.
The 20-time major winner lost her opening service game, but held to love to move to 1-2 and then recovered in the sixth game to level 3-all. She then put her experience to use to close out the set 6-4.
Williams raced to a 3-0 lead in the second set before saving three break points in the fifth game to move 4-1 clear at whose point there was no denying the 33-year-old victory against a player ranked 113 places below her.
“She came out so fast, I was like ‘if I don’t start I’ll be down a set’ and I’m so tired of being down a set,” the world No. 1 said. “It feels good to be back here at Wimbledon. I’ve done so well here in the past.”
