US star Jessica Pegula has launched her season by making the quarter-finals while top seed Elena Rybakina saw off her sternest test of the year to also make the last eight of the Adelaide International.
Bernarda Pera's powerful left hand, which took her to an upset victory over former world No.2 Paula Badosa in the opening round, also shook her American compatriot Pegula in the early stages of their round-of-16 clash on Wednesday.
