NEW YORK (AP) — Hataw si Serena Williams sa naiskor na 18 ace tungo sa 6-0, 4-6, 6-3 panalo kontra Kaia Kanepi ng Estonia para makausad sa quarterfinals ng US Open nitong Lunes sa Flushing Meadows.

"It was a 'Serena scream.' I don't try to do it. It just comes out, and it's just emotions," pahayag ni Williams, six-time US Open champion.

"This is my job and this is what I do. This is how I earn a living. I'm going to do it the best I can. Winning a big game and a very important game and a really tight game, I think it was just a relief."

Samantala, nakausad din si defending champion Sloane Stephens nang pabagsakin si No.15 Elise Mertens ng Belgium, 6-3, 6-3.

'Pikon daw?' UAAP fan na nag-dirty finger, agaw-eksena sa San Juan Arena!

"You are not describing that point good. But I know what you're talking about," pahayag ni Stephens.

"She hit a drop shot. I hit a drop shot back. Then she lobs me to my forehand. I ran back and hit a forehand cross-court — and the crowd went crazy," aniya.
