Adelaide international qf

Adelaide International QF: Defending champion Madison Keys suffered a shock exit from the Adelaide International on Thursday, crashing out in the quarter-finals after a three-set defeat to Canada’s rising star Victoria Mboko.

World No. 17 Mboko, 19, defeated ninth-ranked Keys 6-4, 4-6, 6-2 in one hour and 53 minutes for her second career victory against a top-10 opponent.

Eighth seed Mboko struck first by breaking Keys early to take the opening set but struggled to match the American’s powerful serving in the second. In the deciding set, Mboko was clinical on serve, winning 75 percent of points on her first delivery and capitalising on the only break opportunity she earned.
