Muguruza motors into Hong Kong quarterfinals

No.4 Garbiñe Muguruza rolled into the quarterfinals of the Prudenital Hong Kong Tennis Open on Wednesday, dispatching Romania's Ana Bogdan, 6-2, 6-1.
The two-time major champion dropped just four games against compatriot Sara Sorribes Tormo in her tournament debut on Tuesday, and continued her blistering form to reach the last eight and a meeting with Luksika Kumkhum, who upset No.8 seed Alize Cornet earlier on Wednesday, 6-4, 4-6, 7-6(5).
"I think it was a very good match and I'm happy with the way I played in important moments," Muguruza said. "It was a long day and a long wait. She hits the ball very hard and is very fast, but I'm happy that I managed that and beat that." 
Muguruza broke serve five times over the course of the 75-minute victory to scored her second win over the Romanian this season, having needed three tough sets to defeat her en route to winning the title in Monterrey this spring. 
"I know tomorrow is a day off and I can train a little bit extra for my next opponent," Muguruza said. "I think the more matches I play, the better it is. I'm looking forward to a lot of matches in this final part of the year, and get a little bit more freedom [on the court]."
In other Wednesday action, unseeded teenager Dayana Yastremska and Kristina Kucova also reached the quarterfinals with straight-set victories, with the latter following up an opening-round upset of No.3 seed Jelena Ostapenko with a 6-1, 6-0 win over Bulgarian lucky loser Viktoriya Tomova.
