Carlos Alcaraz and Alexander Zverev make a blistering start in the ATP Finals

The ATP Finals kicked off in Turin with a stark reminder about pedigree and passion. Carlos Alcaraz dismantled Alex de Minaur 7-6(5), 6-2 in the opening match, while Alexander Zverev fought his way past Ben Shelton 6-3, 7-6(6) later in the evening. The Finals is perhaps the most coveted title outside of the majors in tennis, and as it is this week, matters far more than November bragging rights.

Alcaraz's path to victory looked treacherous at first. De Minaur, a player who's carved out a reputation as a nuisance against the elite, bullied his way back from a 4-1 40-0 deficit to drag the opening set to a tiebreaker. At 5-3 up, the Australian seemed positioned to steal it. Then came the collapse. Alcaraz reeled off four straight points from that deficit, a reminder of what separates the top deck from everyone trying to climb up.

Alcaraz lost his opening service game in the seocnd, but barely flinched. Breaking back immediately, he proceeded to rattle off three consecutive breaks of serve, dismantling De Minaur's resistance with precision forehands and the kind of court positioning that makes his opponent look immobile. Ninety minutes, done. The scoreline doesn't capture the gulf in quality during those final forty minutes. The Spaniard produced 32 winners and 28 unforced errors—to push his way through a straight set victory.

“This tournament is one of the best tournaments we have on Tour, without a doubt,” Alcaraz said. “We’re playing against the best players in the world, which shows how difficult and important it is. I’ve been struggling in the past few years to come to the end of the year with motivation. This year is a little bit different, which I’m proud about [as] I’m doing the right things to give myself a shot to try and win this tournament.”

Zverev's victory carried different weight. Shelton, making his ATP Finals debut after a career-best season, came with legitimate credentials. Zverev served well, but even more importantly penalised his opponent's second serve to eke out an emphatic win in 93 minutes. Zverev won 16 of 21 points when returning the second delivery, while also taking 44 of 54 points on his own serve. The German hurt his ankle in a semifinal loss to Jannik Sinner in Paris, but looked no worse for it on Sunday. Shelton led 4-0 in the tiebreaker but netted a simple forehand at 6-5, surrendering the momentum.

“He’s an unbelievably aggressive player. Probably one of the most aggressive in the world,” said Zverev of Shelton. “In the tie-break, he started off amazing. Yes, I missed maybe one or two first serves and the passing shot he hit (at 5/4) was ridiculous. I felt like I had to control the things that I could control and I was doing them well.

“At the end of the day, when the point is on his serve it is always in his control. When I get the return back and in the rally, then I can do something. I did that well at the end of the tie-break and I’m super happy with that win.”

Alcaraz enters Turin chasing something he's never won—this tournament—while simultaneously hunting year-end No. 1 status. He leads Jannik Sinner by 1,050 points, but that margin evaporates quickly in a five-match sprint. Alcaraz needs 450 points to guarantee No. 1 regardless of Sinner's performance. The win on Sunday puts him halfway there, and now comfortably the favourite to end the year at the top of the rankings.

Sinner, conversely, must defend his title, and hope that Alcaraz loses two of his round robin matches. The Italian was immaculate here last year, 5-0 through the group stage. Yet recent form suggests vulnerability. He's laboring on hard courts despite his reputation. If Alcaraz reaches the final, year-end No. 1 belongs to the Spaniard no matter what happens on court. Sinner faces a reality where losing even one group-stage match makes his title quest nearly impossible.

Zverev's clinical efficiency suggests the German could be the tournament's X factor. He's won this twice before (2018, 2021) and moves to 1-0 in the Bjorn Borg Group. With Shelton deflated and Auger-Aliassime still to come, Zverev's path to the knockout stage looks manageable.
