Daniil Medvedev joked that the information he had gathered on opponent Terence Atmane from players on the ATP Tour had proved inaccurate. "He's just coming to tour so I didn't know much about him...," he said.

"Everyone told me he had a better forehand than backhand. But if you look at the stats, he missed like three backhands. Thanks guys." 1449 MEDVEDEV THROUGH TO SECOND ROUND

Medvedev reached the second round when opponent Atmane retired, with the Russian third seed leading 5-7 6-2 6-4 1-0. Atmane appeared to pull up with cramp and initially soldiered on but decided he could not continue after dropping the third set and being broken early in the fourth.

1315 GAUFF STEAMROLLS SCHMIEDLOVA Reigning U.S. Open champion Coco Gauff, the fourth seed in Melbourne, secured a comfortable 6-3 6-0 win over Anna Karolina Schmiedlova of Slovakia at Rod Laver Arena to secure a spot in the second round.

1232 VONDROUSOVA STUNNED BY YASTREMSKA Wimbledon champion Marketa Vondrousova crashed to a shock first-round defeat by Ukrainian qualifier Dayana Yastremska, who thumped the seventh-seeded Czech 6-1 6-2.

Yastremska's compatriot, 19th seed Elina Svitolina also made a fast start with a 6-2 6-2 win over local hope Taylah Preston. 1114 PLAY UNDERWAY
