MELBOURNE, Australia — Two days after beating Venus Williams in the first round, Belinda Bencic is out of the Australian Open.

Bencic, who defeated Williams, 6-3, 7-5, started out flatly and never recovered in losing to qualifier Luksika Kumkhum, 6-1, 6-3, in a match on Melbourne Park's third show court.

Bencic, who has reached a career high No. 7 ranking but entered the Australian Open at No. 78, had beat the 124th-ranked Kumkhum in straight sets in both previous matches they'd played.

Fourth-seeded Elina Svitolina has rallied to reach the third round with a 4-6, 6-2, 6-1 win over Katerina Siniakova of the Czech Republic.

Svitolina was 0 for 6 on break-point chances in the first set, but recovered to break Siniakova six times over the rest of the match.

The Ukrainian has now matched her best showing at the Australian Open, having reached the third round in four of the past five years. She's never advanced beyond the third round, however.

Svitolina comes into this year's tournament on a roll, winning her 10th career title at the season-opening Brisbane International. She beat two top-10 players to take the trophy.

Ukrainian women went 3-for-3 in second round matches on Wednesday afternoon, with 15-year-old Marta Kostyuk and Kateryna Bondarenko also advancing. Svitolina plays Kostyuk next.
