Zhuhai - Top-seeded Johanna Konta advanced to the semi-finals of the Elite Trophy by beating Caroline Garcia 6-2, 6-2 on Friday.
Konta converted four of five break points to eliminate Garcia and set up a semi-final match against Elina Svitolina.
"I really felt I played a very consistent match," Konta said. "I didn't give her many windows and I'm very happy I managed to do that today."
Third-seeded Petra Kvitova also advanced, beating Barbora Strycova 6-1, 6-4.
Kvitova hit seven aces and saved all six break points she faced to improve to 7-1 against her ninth-seeded opponent.
