Australian Open champion Keys knocked out by Pegula in fourth round

MELBOURNE, Jan 26 : Defending Australian Open champion Madison Keys was knocked out of the Melbourne Park Grand Slam after a 6-3 6-4 loss to fellow American Jessica Pegula at Rod Laver Arena on Monday.

Keys struggled to cope with Pegula’s aggressive tennis from the start and was too error prone to stop her title defence from ending in the fourth round.
