Barty, Osaka advance, Nadal has walkover in Aussie warmups

MELBOURNE, Australia (AP) — Top-ranked Ash Barty advanced to the Adelaide International semifinals with a 6-3, 6-4 win over 2020 Australian Open champion Sofia Kenin and Rafael Nadal advanced in Melbourne via a walkover in tune-up tournaments ahead of the year’s first Grand Slam event. Barty used her usual backhand slice and powerful forehand drive but also hit 17 aces and won 31 of 32 points on her first serve to advance. Barty lost to Kenin in the Australian Open semifinals at Melbourne Park two years ago. Nadal advanced without taking the court when Dutch opponent Tallon Griekspoor withdrew.
