Sinner and Alcaraz chase year-end top spot in ATP Finals

TURIN, Italy :Jannik Sinner and Carlos Alcaraz are poised to reignite their rivalry at the ATP Finals, with the year-ending championship that begins on Sunday expected to produce another title showdown between the pair in a season that has belonged to them.

The dominant duo of men's tennis have shared the four Grand Slams this season, facing off in three finals, to set the stage for another encounter in Turin that will decide who walks away from the Inalpi Arena with the bragging rights.

Up for grabs in the Nov. 9-16 finale is the year-end world number one ranking, with Sinner needing a flawless run to remain on top, while Spaniard Alcaraz can leapfrog him with a string of early victories or a run to the final.

"Ending as the world number one has been an important goal for me. In the beginning (of the year) I didn't think about it," said Alcaraz, who leads Sinner by 1,050 points in the ATP Live Race that serves as the measuring stick.

"I'm really motivated to perform well, play my best tennis, try to get some wins and qualify for the semi-finals. Doing good in this tournament, winning matches, comes together with ending the year as the number one. It's the same motivation."

An unbeaten singles champion would also walk away with a little more than $5 million, apart from 1,500 points. The $15.5-million event will also feature the best eight doubles teams in a similar round-robin format before the semi-finals.

BACK TO THE SUMMIT 

Alcaraz had reclaimed top spot by reaffirming his dominance over Sinner in their head-to-head battles with a win in the U.S. Open final in September but an early Paris Masters exit allowed his Italian rival to climb back to the summit with the trophy.
