Naomi Osaka brushed aside Anett Kontaveit to reach the US Open quarter-finals on Sunday.
The fourth seed is the favourite for the women's crown at Flushing Meadows and showed exactly why as she hit Kontaveit off the court in a 6-3 6-4 win on Arthur Ashe Stadium.
Osaka hit 21 winners and showed no signs of the hamstring injury which saw her withdraw from the final of last week's Western & Southern Open.
The 2018 champion now meets Shelby Rogers in the last eight and will have her eyes on a third grand slam title.
"For me I haven't played her in a while, she is a great player," Osaka said. "I am just going into it very optimistic. I feel like I would be the underdog having never beaten her. I am happy to be still here.
"My leg felt better, I felt like I was moving well so I am happy about that."
Osaka will play Shelby Rogers, who knocked out no.6 seed Petra Kvitova, for a place in the semi-finals.
