It is only fitting that the penultimate ATP World Tour Masters 1000 event on the calendar is down to the players who have dominated the tour all year.

World No. 1 Rafael Nadal will attempt to extend his 16-match winning streak Sunday in pursuit of his first Shanghai Rolex Masters title in the final against World No. 2 Roger Federer. Nadal is trying to earn a record 31st Masters 1000 title, which would break his tie with Novak Djokovic at 30 each. A victory will almost guarantee that the Spaniard closes the year with the No. 1 Emirates ATP Ranking for the fourth time, as he would own a 2,760-point lead over Federer. The Swiss seeks to narrow the gap in the race for the year-end No. 1 as well as earn his second trophy in Shanghai, which would give him his 350th Masters 1000 victory.

The Nadal-Federer rivalry is being renewed for a 38th time in the first Chinese final between the Top 2 players in the Emirates ATP Rankings since Beijing in 2013.

This is the rivals’ fourth meeting of the season, with Federer trying to win his fifth match in a row against Nadal dating back to Basel in 2015. He beat the Spaniard in the final at the Australian Open and the Miami Open, while also defeating him in the Round of 16 at BNP Paribas Open.

Nadal leads their FedEx ATP Head2Head series 23-14 (Federer leads 10-9 on hard courts), but the Swiss has won the past four matches, a first for him in the rivalry. The 36 year old has also captured the past five sets in the matchup, the first time he has done that as well. He says that despite the overall head-to-head record, Nadal has made him a better player.

“I don’t want to thank him for that, but he made me maybe rework my game and go back to the practice courts and think about what I could change maybe to become a better player,” Federer said. “I think for that I’m happy about the losses I took. Took them on the chin and kept moving forward. It’s nice at this late stage of the career that we still have these matches going on.”

Federer is making his third appearance in the Shanghai final (1-1) and his first since winning the 2014 title (d. Simon). He was also a finalist in 2010 (l. to Murray). Federer is 5-1 in finals this season and is competing in his 143rd final (93-49).

Most FedEx ATP Head2Head Meetings

Federer’s next title will tie Ivan Lendl for second place on the Open Era titles list with 94 (Jimmy Connors holds the record with 109). He already owns the most Masters 1000 wins with 349 and is No. 3 in Masters 1000 titles with 26 behind Nadal and Djokovic. Federer is 9-1 this season against Top 10 opponents with his only loss coming in the Coupe Rogers final against Alexander Zverev.

Nadal is 14-9 in finals against the Swiss and owns a 12-6 advantage in Masters 1000 tournaments (7-4 in finals). The Spaniard is appearing in his second Shanghai final, his first since the 2009 inaugural tournament (l. to Davydenko). The 31 year old is playing in his 10th final (6-3) of the season, which leads the tour. This is the fifth time the left-hander has appeared in at least 10 finals in a season, the first since 2013 when he reached a career-high 14 finals (10-4).

On Sunday, Nadal plans on focusing on maintaining his own level, which helped him regain the No. 1 ranking this season.

“I’m going to do my thing. I know what I have to do. I know it’s very difficult, and especially in this kind of surface. But the most important thing for me is play at my highest level,” Nadal said. “If that happens, I hope to have my chances. If that doesn’t happen, the chances will be much less. But I am playing well, and I am focused on trying to make that happen.”

Considering there were concerns he might not even be able to take the court against Roger Federer, Juan Martin del Potro gave the fans a semi-final to savour at the Shanghai Rolex Masters on Saturday.

After his three-set victory over Viktor Troicki in the quarter-finals, del Potro’s communications manager, Jorge Viale, posted on Twitter that the Argentine had his wrist in a splint and would decide on Saturday morning if he could play against Federer. While not a serious injury, del Potro had suffered a wrist contusion.

But play he did and the Tandil native had Federer in all sorts of trouble as he took the first set against the Swiss. The tide turned when Federer broke in the sixth game of the second set, converting his fifth break point. The World No. 2 would go on to win the match, with del Potro crediting the Swiss’ aggressiveness and improved serving as the deciding factor.

“He took the confidence after that game,” reflected del Potro. “He broke me and he started to play more aggressive. He served much better after that game. I think he beat me in a good way. He played better in just couple of moments in both sets, and that was the only reason for my loss.”

Del Potro admitted he only decided when warming up for the match that he would play, having been advised it would not risk his wrist.

“I have been playing good tennis this week, but I felt good during the warm-up before the match, and I decided to play, because against Roger always is an honour to play,” said del Potro. “The court was really fast, so maybe that would help my game.

“I think I did well, but Roger played much better than me some moments of the match, and he took the chances. It’s very painful now after the match. After a big effort is the worst moment for my wrist.

“Now I have few days to take a rest. If, in these days I feel better to compete 100 per cent during the whole tournament, I will continue with my schedule.”

Moving on, Federer will play Rafael Nadal in a blockbuster final at the ATP World Tour Masters 1000 tournament. In what will be their 48th meeting, del Potro thinks Nadal is the only player capable of beating Federer in this form on the fast Shanghai courts.

“I think the court helps [Federer’s] game a lot, and he always is in good shape,” said del Potro. “He looks like an unbelievable athlete. I think on this court not many players can beat him. Maybe Rafa tomorrow, but if not, he’s the only one who can play an excellent tennis on this faster surface.

“Rafa is playing so good, but I think Roger could win if he feels the ball really, really well. Because the court is so fast, and for the game of Roger it is much better than Rafa’s game, but Rafa is a fighter and he never gives up. It will be interesting to watch.”

Roger Federer will face longtime rival Rafael Nadal for the fourth time this season after coming from a set down to defeat Juan Martin del Potro, 3-6, 6-3, 6-3 at the Shanghai Rolex Masters. The 2014 champion advances to his third final at the ATP World Tour Masters 1000 event.

After failing to capitalise on four consecutive break points while down a set and up 3-2 in the second set, it appeared that Federer might be denied a meeting with World No. 1 Nadal for the second time in as many months by the Argentine, who defeated him in the quarter-finals at the US Open. But when del Potro missed a forehand wide on the fifth consecutive break point he faced, the 29 year old gave the Swiss all the momentum he needed to turn the match around.

The 36 year old did not face a break point in the final two sets, and broke twice in the decider to advance in one hour and 58 minutes.

Federer will meet Nadal for the third time in a final in 2017. The Swiss has won on all three occasions, and will look to close a 14-23 deficit in the pair’s FedEx ATP Head2Head rivalry.

More to come.
