Sakkari, who started the week with a decisive victory over American teenager Coco Gauff, trailed by a set and a break in her first meeting with the 23-time Grand Slam champion only to roll through the final set after two hours and 17 minutes to win the match 5-7, 7-6(5), 6-1 on Tuesday evening.

“I haven’t realised it yet,” Sakkari said after the match as per the WTA website. “It feels pretty good, because she (Williams) has been a role model for me growing up, and obviously what she has achieved is huge. So it feels very nice.”

“I was not feeling good. This first set and a half, I could not feel my shots. There were some points where I was playing good, but I knew it was going to be ugly.

“I’m kind of proud of myself that I came through that match just because of my mentality and my fighting spirit,” she added.

 “It was tough,” Williams said after the match. “I literally should have won that match. There was no excuse.”
