Elena Rybakina, who won Sunday's Brisbane International, and Jessica Pegula are the top women's seeds.

Tommy Paul is the top seeded player in the ATP portion of the tournament.

In a first-round result on Monday, Jack Draper beat fifth seed Sebastian Baez 6-1, 6-3.

MERTENS ADVANCES AT HOBART

At the Hobart International WTA tournament, top seed Elise Mertens, who won the tournament in 2017 and 2018, beat 2022 Australian Open finalist Danielle Collins 6-2, 6-3.

"(Collins is) definitely a tough opponent in the first round. She can definitely strike the ball very hard. The weather was in my advantage, a little bit more wind," Mertens said.

The Belgian player next faces Slovakia's Anna-Karolina Schmiedlova, who beat fellow qualifier Maria Camila Osorio Serrano 1-6, 7-6, 7-5.

EUBANKS BOWS OUT IN AUCKLAND

In New Zealand, Chris Eubanks struggled with a muscle injury before being eliminated from the ATP Auckland Classic in the first round on Monday.

Fifth seed Eubanks needed courtside treatment for a glute muscle injury and lost 7-6, 6-2 to Botic van der Zandschulp.

It is not yet clear whether the injury will impact Eubank's Australian Open campaign.

The big serving American indicated he was in trouble late in the first set and called for the tour trainer.

He received treatment between sets and elected to play out the match.

But he looked limited at times and unable to run at full stretch.

Van der Zandschulp converted his third break point in the second game of the second set to lead 2-1 and broke again at 5-2 to take the match at his first opportunity.

"I'm pretty happy with my performance. I think I played a decent level overall," van der Zandschulp said.

"Chris is serving amazing and you have to keep up every time. If you don't pay attention for just a couple of seconds you can be broken and it's tough to break him."

Earlier on Monday, Daniel Altmeier beat American Marcos Giron 7-6, 6-2 and Luca van Assche beat JJ Wolf 6-4, 6-2.

French veteran Gael Monfils also was beaten in the first round, losing 6-2, 6-7, 7-6 to Fabian Marozsan of Hungary.

The 37-year-old Monfils at times looked near exhaustion in the latter part of the match, slumping over a chair between points as the match dragged on against an opponent 13 years younger.

Yet he kept coming back to win clutch points.

He served for the match at 5-4 in the second set but Marozsan saved and rallied to win the match in the final tiebreaker.

Monfils spent all of the last week courtside in Auckland, following his wife Elina Svitolina as she reached the final of the women's Auckland Classic before losing in three sets to defending champion Coco Gauff.
