Carlos Alcaraz, Ons Jabeur, Emma Raducanu, Stefanos Tsitsipas sign off from Abu Dhabi

WATCH: Ons Jabeur beat Emma Raducanu in the women's exhibition at the Mubadala World Tennis Championship.

With less than two weeks until the start of the 2023 tennis season, it's a sure bet that Ons Jabeur and Stefanos Tsitsipas are ready to go after they were the winners of this weekend Mubadala World Tennis Championships in Abu Dhabi.

In the fifth edition of the women's exhibition, Jabeur beat Emma Raducanu on Friday 5-7, 6-3, [10-8] to win the title for the second straight year in a place she says "feels like home."

A year after she'd first hoped to, Raducanu seemed to enjoy her long-awaited Abu Dhabi debut. The Brit was supposed to compete against Belinda Bencic in last year's women's exhibition match, but came down with COVID-19 and couldn't play.

Amid reports she's taken on a new coach, Sebastian Sachs, Raducanu hit the court for the first time since her 2022 season ended prematurely due to a wrist injury.

She looked strong against world No. 2 Jabeur: Raducanu four straight games from 5-3 down in the first set, but failed to convert an 8-6 lead in the 10-point match tiebreak.

In the six-player men's event, third-seeded Tsitsipas won the title with a 6-2, 4-6, 6-2 win over No. 4 seed and defending champion Andrey Rublev. Previously, he beat fifth seed Cameron Norrie (6-1, 6-4) in the quarterfinals, and No. 2 seed Casper Ruud (6-2, 6-2) in the semifinals.

But perhaps the most notable participant in the UAE's capital city was world No. 1 Carlos Alcaraz, who played his first competitive tennis of any kind since he suffered an abdominal tear against eventual champion Holger Rune in the quarterfinals of the Rolex Paris Masters.

Forced out of both the ATP Finals and the Davis Cup Finals, Alcaraz nonetheless ended the season as world No. 1, the youngest to ever do so, and was awarded Most Improved Player of the Year honors.

Though he went 0-2 in Abu Dhabi with a semifinal loss to Rublev (6-2, 6-1) and a third-place loss to Ruud (6-1, 6-4) in a rematch of the US Open final, the teenager was in good spirits on social media in the aftermath.

Looking ahead, Tsitsipas and Ruud will represent Greece and Norway, respectively, in the inaugural mixed-gender United Cup that begins in Australia on Dec. 29.

Jabeur will officially open her 2023 season at the first of two WTA 500 events in Adelaide, while Raducanu will head to Auckland, New Zealand for the return of the ASB Classic.
