Rafael Nadal and Novak Djokovic are set to battle for the No. 1 ATP Ranking next week in Paris as the Spaniard returns from injury to take his place atop the Rolex Paris Masters draw.

Playing his first match since retiring during the US Open semi-finals with a knee injury, Nadal enters the tournament with a 215-point lead over Djokovic in the ATP Rankings. But the Monday after the tournament the Spaniard will drop the 180 points he earned by reaching the Paris quarter-finals last year. So, with the 5 November Rankings in mind, Nadal in effect holds a razor-thin 35-point lead in the 52-week ATP Rankings over Djokovic, who missed Paris through injury last year and has no points to defend.

Nadal has held top spot since 25 June after several lead changes with Roger Federer earlier in the year. The 33-time ATP World Tour Masters 1000 champion has held the No. 1 ATP Ranking for 195 weeks, sixth in the all-time list (since 1973).

Should he dethrone Nadal on 5 November, Djokovic would be the first player to come from outside the Top 20 and reach No. 1 in the same season since Marat Safin in 2000. (Safin was as low as No. 38 on 28 February 2000 before becoming No. 1 on 20 November 2000). Djokovic, who underwent elbow surgery in February, began the year with a 6-6 record and slipped to No. 22 on 18 June.

He has spent a total of 223 weeks at No. 1 but last was on top on 31 October 2016. In Paris Djokovic is also trying to win a third consecutive ATP World Tour Masters 1000 title (Cincinnati, Shanghai) and equal Nadal’s record of 33 titles at the elite level.

Whichever player finishes one round better than the other in Paris will be No. 1 on 5 November. Should they both lose in the same round, Nadal will be No. 1. Regardless of what happens in Paris, the coveted year-end No. 1 ATP Ranking will be decided at the Nitto ATP Finals, to be held 11-18 November in London, where 1,500 points await an undefeated champion. Both Nadal and Djokovic are attempting to finish year-end No. 1 for a fifth time, tying Roger Federer and Jimmy Connors and moving closer to Pete Sampras’ record of six year-end finishes at the top.

Seeking his first Rolex Paris Masters title, Nadal will open against the winner of French veteran Jeremy Chardy and fellow lefty Fernando Verdasco, who has a history of pushing his countryman to the limit. Should he reach the quarter-finals, Nadal is projected to meet Dominic Thiem in what would be a reprise of their epic US Open quarter-final last month, which Nadal won in a fifth-set tie-break.

Djokovic, who opens against the winner of a qualifier and his Roland Garros conqueror Marco Cecchinato, is seeded to meet fast-rising World No. 16 Stefanos Tsitsipas in the third round. The Serb was one of four Top 10 victims the #NextGenATP Greek claimed en route to the final of the Rogers Cup in August. Tsitsipas won his first ATP World Tour title last week in Stockholm and is alive in this week’s Basel quarter-finals. In the quarter-finals, four-time tournament champion Djokovic is seeded to meet Marin Cilic, who is chasing one of the three remaining spots at the Nitto ATP Finals.

In Djokovic’s bottom half of the draw, third seed and 2011 champion Federer is looking at a challenging opening-round match against the winner of Milos Raonic and 2008 champion Jo-Wilfried Tsonga. Should he reach the quarters, Federer would face Kevin Anderson or Kei Nishikori, both of whom are chasing London berths.

Another London hopeful and former Paris finalist, John Isner, opens against the winner of Pierre-Hugues Herbert and Mikhail Kukushkin, with a potential third-round challenge against Karen Khachanov or Filip Krajinovic, who defeated the American in a third-set tie-break in last year’s semi-finals.

Fourth seed Alexander Zverev, already a winner of three ATP World Tour Masters 1000 titles, opens against a qualifier or #NextGenATP American Frances Tiafoe. He is seeded to meet Isner in the quarter-finals, in what would be a re-match of this year’s Miami final.

Main draw play begins Monday.

Top seed Roger Federer was made to dig deep in the Swiss Indoors Basel quarter-finals, battling past French veteran Gilles Simon 7-6(1), 4-6, 6-4 on Friday.

“Sure, Gilles came back. But I found a way, which was most important, so I’m really happy now,” said Federer, who is into his 200th tour-level semi-final. “It was always going to be at times a frustrating match, because you’re always going to hit winners and errors against Gilles because he puts so many balls in play.”

The 37-year-old has now reached the semi-finals at his hometown tournament in 12 consecutive appearances. The Swiss is 15-1 in Basel quarter-finals, with his only loss at this stage of the event coming 19 years ago against then-World No. 6 Tim Henman. Federer was just 18 years old.

The eight-time champion and 13-time finalist has now won 18 consecutive matches at the ATP World Tour 500-level event, where he is pursuing his 99th career tour-level trophy. If Federer goes on to triumph this week, he’ll earn his fourth title of the season, finishing in the winners’ circle that many times in a year for the 14th time.

And while Federer got through after two hours and 34 minutes, it was anything but easy for the Swiss.

Simon has shown good form this year, winning titles in Pune and Metz. And the Frenchman showed it against Federer, keeping the home favourite from gaining any rhythm, especially off his dangerous forehand side. Simon served for the opening set, and then held a set point on the eight-time champion’s serve while leading 6-5. But Federer, who made a slew of unforced errors off the forehand wing early, reduced his mistakes to cruise through the ensuing tie-break.

But the Frenchman maintained his focus, mixing up his paces well in the second set to continue frustrating the Swiss, forcing a decider. But despite coughing up an early break in the third set, Federer stayed the course and advanced, despite getting broken five times, when Simon missed a two-handed backhand long. Federer has now won seven consecutive FedEx ATP Head2Head matches against Simon, leading their rivalry 7-2.

“I really enjoyed it. I think I also showed emotions, I was trying to pump myself up,” Federer said. “It’s an absolute pleasure playing on home soil with the crowd supporting me so much. I think they felt like I was in danger, and it was nice that they were there every step of the way.”

Federer will next face Russian Daniil Medvedev, who beat #NextGenATP Greek Stefanos Tsitsipas 6-4, 3-6, 6-3. It will be a re-match of the pair’s first FedEx ATP Head2Head meeting, which took place earlier this month at the Rolex Shanghai Masters, where Federer won in three sets.

Medvedev now leads the ATP World Tour with 37 hard-court match wins in 2018, breaking a tie with Argentine Juan Martin del Potro. Tied for third on the list are Kevin Anderson and Federer, with 30 wins apiece on the surface.

Medvedev is playing his best tennis, recently claiming his maiden ATP World Tour 500-level trophy at the Rakuten Japan Open Tennis Championships 2018 in Tokyo, which was his third trophy of the season (also Sydney and Winston-Salem). The 22-year-old cracked the Top 20 of the ATP Rankings for the first time this week at No. 20.

“I think it’s going to be a tough semi. I’m very excited, apparently it’s my 200th semi-final on the Tour,” Federer said. “It’s something I’m very excited about, that it also happened here in Basel.”

Watch Highlights Of Federer’s Win In Shanghai Against Medvedev

Alexander Zverev continues to build momentum with less than two weeks to go until the Nitto ATP Finals, defeating Spaniard Roberto Bautista Agut 7-5, 6-3 on Friday to reach the semi-finals of the Swiss Indoors Basel.

Before the recent Rolex Shanghai Masters, Zverev failed to reach the semi-finals in four consecutive tournaments. But since arriving in Shanghai, the 21-year-old has won six of seven matches, with all six of those victories coming in straight sets. The second seed leads the ATP World Tour with 52 match wins this season.

The World No. 5 is trying to win his 10th ATP World Tour title, and his fourth of the season. No German has triumphed in Basel since 1994, when Michael Stich lifted the trophy. In the tournament’s history, since 1975, only one other German has emerged victorious at the event: Boris Becker in 1993.

Zverev and Bautista Agut battled it out from the back of the court throughout the match, with both players attempting to hold their ground on the baseline. The Spaniard did well to keep Zverev from controlling points with his flat, penetrating groundstrokes. But the German had too much weight of shot, and his weapons — especially his two-handed backhand — were ultimately too strong for the eighth seed.

Zverev, whose lone previous appearance in Basel came four years ago, now leads Bautista Agut 4-2 in their FedEx ATP Head2Head series. He has won eight of his past nine sets against the Spaniard.

In the next round, Zverev will face Romanian Marius Copil, who ousted #NextGenATP American Taylor Fritz 7-6(6), 7-5. The qualifier, who has not lost a set in qualifying or the main draw, advanced to his first ATP World Tour semi-final and final earlier this season in Sofia, ultimately losing to Mirza Basic in the championship match.

Copil is currently No. 93 in the ATP Rankings, but he also defeated London hopeful and third seed Marin Cilic in the second round. Against Fritz, Copil struck 18 aces and saved 10 of the 11 break points he faced to advance after one hour and 52 minutes.

For the first time in men’s professional tennis, Video Review will be used by officials at the Next Gen ATP Finals, the ATP’s ground-breaking season-ending event for the world’s best 21-and-under players, set to take place in Milan, Italy, from 6-10 November.

The Video Review, delivered using advanced Hawk-Eye technology, will provide opportunities for players to challenge any judgement calls from the Chair Umpire such as Not-Ups, Foul Shots, Touches, or Invasion*. The incorporation of Video Review in Milan represents the latest innovation by the ATP at its bold and ambitious season-ending event for the best 21-and-under players in men’s professional tennis.

Chris Kermode, ATP Executive Chairman & President, said: “Innovation is at the heart of everything we do at the Next Gen ATP Finals, and we’re looking towards the future in all aspects of this tournament. Adding Video Review will give players a new tool that will further enhance the officiating in our sport. The Next Gen ATP Finals continue to position the ATP at the forefront of innovation in tennis as we also look to deliver on our mission to provide a global stage for the future stars of the ATP World Tour.”

Gayle David Bradshaw, Executive Vice President, ATP Rules & Competition, said: “Controversy with these types of decisions are rare but when they do occur they can be particularly unsettling for players. We do not expect a lot of challenges, but should any instances arise, this technology will ensure the correct decision is reached.”

The Hawk-Eye technology behind the Video Review will use video feeds from all television cameras so that the Video Review operator can quickly search footage to find the correct angle for the decision to be made. The relevant footage will be sent to the Chair Umpire’s tablet who will review the video and decide whether to uphold or overturn the original call. All relevant footage will be played out to the in-house spectators on large video boards in real time, as well as on broadcast, to take the audience even closer to the action. There will be no limit to the number of Video Review challenges a player is able to make.

Future use of Video Review could include decisions on whether to award the point or replay the point in the case of a corrected out to good call by an official. In Milan, however, such instances will not arise as all calls made by Hawk-Eye Live are final.

Peter Irwin, Hawk-Eye Innovations Solutions Director, said: “We are delighted to be partnering with the ATP on this ground-breaking introduction of Video Review into professional tennis. Having had years of experience providing our SMART Replay technology for officiating purposes in many other sports, we firmly believe it can bring huge benefits to tennis. Tennis fans are used to Hawk-Eye’s ball tracking technology being used to decide if a ball is in or out, but Video Review will work alongside this to assist officials make the correct decision on other judgement calls. With Hawk-Eye Live again being used in Milan to call the lines live, the use of Video Review to help adjudicate on all other decisions means the players at this year’s Next Gen ATP Finals will get the highest level of officiating they’ve ever had.”

The 2018 tournament will continue with many of the innovations trialed at the inaugural event, with the addition of the Video Review, a further reduced warm-up (4 minutes), as well as the incorporation a towel rack at the back of the court which will remove the onus on all ball kids to handle player towels.

The 2017 edition of the Next Gen ATP Finals, held in partnership with the Italian Tennis Federation and the Italian National Olympic Committee, was one of the boldest integrated presentations of innovation in sport to date. The tournament, which is set to stay in Milan through to 2021, comes at a key time when innovation is being widely considered across the highest levels of the sport. The success of the inaugural tournament was recognized at the Yahoo Sports Technology Awards in London, where ATP & ATP Media won the Most Innovative Governing Body or Rights Holder Award, as well as at the Leaders Sports Awards, where the tournament was recognized with the award for Best Innovation.

Notes to Editors:

*Examples of incidents that would be subject to Video Review at the Next Gen ATP Finals are:

• Not-Ups – double bounces
• Foul Shots – for example, deliberate double hits or carry; or hitting the ball before it has passed the net; the ball, prior to bouncing, hits a permanent fixture; or the racquet is not in the player’s hand when touched by the ball.
• Touches – ball skimming racquet, clothing or body; or if a player, or anything he is wearing or carrying, touches the net, net posts/singles sticks while the ball is still in play.
• Invasion – player, or anything he is wearing or carrying, touches the opponent’s side of the court while the ball is in play.
