Why is Tuesday the biggest day of the week?

Tuesday 27 October 2026 is the biggest day of the Vienna and Basel week because four separate storylines, each of which could headline a tournament on its own, all land on the same day. In Basel, Novak Djokovic plays his first match at the Swiss Indoors since 2011, and Stan Wawrinka plays the first match of his final tournament. In Vienna, Carlos Alcaraz plays his first match of the week, and Alexander Zverev continues a run that could take him to world No 1 for the first time. Both tournaments are ATP 500 events, played on indoor hard courts, with 32 player draws and no byes, so every seed must play from the first round. Both finals are on Sunday 1 November. The Paris Masters, from 2 to 8 November, is the cutoff event for the ATP Finals in Turin from 15 to 22 November, so every win this week changes the Race to Turin. That is why Tuesday matters beyond the individual matches: it is the day when the Race starts to move.

What is at stake for Novak Djokovic in Basel?

Novak Djokovic, the fourth seed in Basel, faces France's Ugo Humbert in the first round on Tuesday. Djokovic is playing in Basel for the first time since 2011, when he lost in the semifinal to Kei Nishikori. He won the title here in 2009, beating Roger Federer in the final, and he has a 12-2 record at the event. He arrives in strong form after winning the Beijing title earlier in October, his 102nd career title. Djokovic is 11th in the Race to Turin, and he needs a strong week to climb into the qualifying places. With Jannik Sinner out for the season with a knee injury, effectively ninth place in the Race now gets into Turin, so Djokovic is chasing a place that is closer than his ranking suggests. One report puts him 319 points behind Rafael Jodar for the last Turin spot, which means a title run in Basel would change the picture dramatically, but even a title might not be enough on its own without other results going his way. Humbert is a dangerous first round opponent, a left hander who is comfortable on fast indoor courts and who can take the ball early. Djokovic will also have a possible quarterfinal against Alexander Bublik and a possible semifinal against top seed Ben Shelton in his half of the draw, so the path does not get easier. If Djokovic wins in Basel, a 103rd career title would level him with Federer, in Federer's hometown, which adds an emotional layer to an already high stakes week.

What is at stake for Carlos Alcaraz in Vienna?

Carlos Alcaraz, the second seed in Vienna, faces Karen Khachanov in the first round on Tuesday. Alcaraz is playing in Vienna for the first time since 2021, after taking a late wildcard into the tournament, and he arrives with a 33-5 record this season. He leads the head to head against Khachanov 6-0, which makes him the favourite, but Khachanov is a former top ten player who can hit through indoor courts when he is confident. Alcaraz's draw does not get easier after Khachanov. He could face the winner of the Paul and Rublev match in the quarterfinals, and Daniil Medvedev is a possible semifinal opponent. Vienna is also a tournament where Alcaraz can build momentum for Paris and Turin, and where he can test his game against the kind of big hitting opponents he will face in the finals. A first round loss would be a surprise, but it would also be a reminder that indoor hard courts in October are unforgiving, even for the best player in the world.

Can Alexander Zverev become world No 1 this week?

Alexander Zverev, the top seed in Vienna, faces Martin Landaluce in the first round on Tuesday, and he is chasing a prize that has eluded him for his whole career: world No 1. Zverev needs two wins in Vienna, to reach the quarterfinals, to become world No 1 effective 2 November, because Jannik Sinner has 500 points dropping from his ranking. That is a remarkably short path to the top of the sport, and it explains why Vienna has suddenly become the most watched tournament of the week. Landaluce is a young Spanish player who will have nothing to lose, and Zverev will need to be sharp from the first ball. If he wins his first two matches, the world No 1 ranking will be his, regardless of what happens in Basel or elsewhere. If he loses early, the chase continues to Paris, but the chance to do it in Vienna, in front of a full house, will have gone. Zverev has been world No 2 before, but he has never been No 1, and that gap in his career record is one of the most discussed topics in tennis this week.

Why is Stan Wawrinka's match so emotional?

Stan Wawrinka, the 41 year old Swiss three time Grand Slam champion, faces eighth seed Jiri Lehecka in the first round in Basel on Tuesday, in what will be his final tournament. Wawrinka has chosen Basel, his home tournament, as the place to end his career, and the match against Lehecka is the first step of that farewell week. Wawrinka is in Djokovic's half of the draw, and a possible semifinal against Djokovic is the dream matchup for the Basel crowd, two veterans who have played some of the greatest matches of the modern era. Whether Wawrinka wins or loses on Tuesday, the atmosphere at the St Jakobshalle will be extraordinary, because the crowd knows this is the last time they will see him play at home. Lehecka, a powerful Czech player, will not be an easy opponent, and he will not be sentimental about the occasion, which is exactly how Wawrinka would want it.

What are the other key first round matches?

Beyond the four headline matches, Tuesday also brings a set of first round matches that could shape both tournaments. In Basel, top seed Ben Shelton leads the field, ahead of Arthur Fils, Rafael Jodar and Djokovic, and the 2025 champion Joao Fonseca is absent, so Basel is guaranteed a new winner. Taylor Fritz meets Stefanos Tsitsipas in another first round blockbuster, and Arthur Fils faces Hubert Hurkacz, the Pole who beat Djokovic in Shanghai. In Vienna, Daniil Medvedev faces Daniel Merida, Flavio Cobolli faces Grigor Dimitrov, and Lorenzo Musetti faces Frances Tiafoe, all on Tuesday's schedule. Those matches matter for the Race to Turin too, because Cobolli, Medvedev and Tiafoe are all chasing points in the final weeks of the season. The full order of play for Tuesday should be checked on the ATP website on the day, because individual match times can change with court scheduling.

How can fans watch Vienna and Basel on Tuesday?

Vienna and Basel are both ATP 500 tournaments, and their television coverage varies by country. In the United Kingdom, Sky Sports covers ATP tennis, and in the United States, Tennis Channel covers both events, with streaming on Fubo. In Germany, France, Spain, Italy and the Netherlands, local ATP broadcast partners carry the matches, and the ATP website and app provide live scores and order of play. For fans in Pakistan, Tuesday's matches fall in the evening Pakistan time, because Basel and Vienna are four hours behind Karachi in October. A match starting in the early afternoon in Basel or Vienna will be in the evening in Karachi, which makes Tuesday a perfect evening of tennis for fans in South Asia as well as Europe.
