Pegula dethrones Keys to reach Australian Open quarter-finals

MELBOURNE, Jan 26 : Jessica Pegula knocked out defending champion Madison Keys at the Australian Open on Monday as the American sixth seed secured a dominant 6-3 6-4 victory to reach the quarter‑finals at Melbourne Park for the fourth time.
