His last outing was at Houston, where he lost to world No.333 Michael Redlicki in three sets.

Venus has no singles ranking and hasn't played solo for a couple of years now, but holds the No.10 doubles spot and - with Aussie John Peers - he's top seed at this tournament.

1:35pm - Real pressure coming on service games now, with Hurkacz breaking Sonego to take the momentum in the second set at 3-1.

1:19pm - Sonego has had to survive three break points early to level the second set at 1-1. 

1:06pm - Hurkacz has finally taken the first set off Sonego 7-5, with the only service break coming in that final game.

An evenly balanced affair saw the Pole squader a couple of break chances earlier in the set, but his return game really tested his rival's serve in the final exchanges.

Sonego served up five aces with no double faults, compared to Hurkacz's 3-1.

12:07pm - Players for the first match of the day are warming up on Centrecourt, with sixth-seeded Pole Hubert Hurkacz facing 51st-ranked Italian Lorenzo Sonego, who has won the only previous encounter between these two.

Hurkacz is ranked 37th in the world.

*****

Kia ora, good morning and welcome to the opening day of play at the ASB Classic men's tournament from Auckland.

After yesterday's climax to the women's event, with Serena Williams holding centre stage, attention now turns to the men, where top seed Daniil Medvedev was an unfortunate late withdrawal.

Men's ASB Classic lacking star power of women's draw

Kiwi Michael Venus could now be the biggest attraction at next week's men's tournament, which lacks the star power of a Serena Williams.

Venus has been given a wildcard the day after top seed Daniil Medvedev's withdrawal.

World No.12 Fabio Fognini has inherited the top billing for the men's edition, which kicks off in Auckland on Monday.

But he doesn't bring with him the star power of Medvedev, a US Open finalist in 2019.

The Russian has decided to rest before the Australian Open later this month, after a deep run with his country at the ATP Cup in Sydney this week. 

"There's a massive tournament the week after us that the players logically want to get ready for," noted tournament director Karl Budge.

"He's [Medvedev] had a massive load this week."

Tournament director Karl Budge tried to fly in some big names for his wildcard spot to bolster the draw, but ultimately, he was forced to turn to Venus - one of the world's best doubles players. 

"We offered brothers wildcards, we offered private jets. We offered a lot to try to get people coming out of Australia and Doha this week." 

The withdrawal does give fans a favourite in Medvedev's absence.

"It could be a good opportunity to start the year - get some point play, before getting on the doubles court," Venus said. 

Venus will play defending champion Tennys Sandgren in the first round.

Despite featuring more top 20 players, the men's tournament lacks the big-name appeal of its women's counterpart, which included two of the biggest names in the sport in Williams and Caroline Wozniacki. 

"Our men's field is quite a lot stronger than our women's field," Budge said. "It just doesn't have man-on-the street appeal that the women's field has enjoyed this week."

But at least Michael Venus can enjoy the spotlight and hopefully get bums on seats.
