Inigo Cervantes will look to clinch the third 50-win season in Challenger history when he faces countryman Daniel Munoz-de la Nava in Sunday’s final at the ATP Challenger Tour Finals.

Cervantes beat home hope and eighth seed Guilherme Clezar 6-3, 7-6(9) to book a spot in his sixth final of the year. The Spaniard, who is projected to rise to at least a career-high Top 85 position in the Emirates ATP Rankings, fired 17 aces and saved both break points faced during the one-hour and 47-minute affair in Sao Paulo. He remains on track to wrap up the first undefeated campaign in the five-year history of the Challenger year-end championships.

“There was only one break during the match,” said Cervantes. “Then a very close tie-break. Clezar is a very dangerous player here. Not only because we’re in Brazil, but also because it’s indoors and fast conditions. His serve is pretty strong so I’m glad that I won the match.”

MOST WINS IN A SEASON

The all-Spanish final clash will be the second of the week between the two compatriots. If the title match is as close as their thrilling round robin encounter in Group A, won by Cervantes 4-6, 7-6(3), 7-5, fans will be in for a treat. It was Cervantes’ second three-set win of the year in the FedEx ATP Head2Head, after prevailing in qualifying of the ATP World Tour 500 event in Hamburg.

“It’s been only a few days since our last match and it was tough, almost three hours,” added Cervantes. “It will be difficult, I’m sure, but we know each other really well and if I play like today, I have a good shot for the title.

“Maybe physically he’s a bit more fresh than me. He had a day of rest and I played almost two hours. But I’ll face this victory in a positive way. It helps me mentally so I can be prepared and without any issues tomorrow.”

Munoz-de la Nava had already sewn up a berth in the final following second seed Guido Pella‘s injury withdrawal prior to Saturday’s semi-finals. Pella suffered a torn adductor muscle in his round robin finale in Group B against Marco Cecchinato on Friday. Madrid native Munoz-de la Nava is 46-17 this year.

Cervantes is 3-2 in Challenger finals this year, seeking his sixth title overall. He lifted trophies in Ostrava, Vicenza and Marburg. Munoz-de la Nava, meanwhile, is 3-3 in title matches in 2015 and will be eyeing a fourth crown overall. He won titles in Napoli, Moscow and Meknes this year.

“I leave with my head up high,” Clezar said. “I had a good tournament. The two matches I lost were more about the opponents’ merits than me playing bad.”

Continuing our Season In Review Series, ATPWorldTour.com revisits the fiercest rivalries of 2015. Today we feature Novak Djokovic vs. Andy Murray:

It’s a rivalry that seems to have been hatched at birth. Novak Djokovic and Andy Murray were born within a week of each other in May 1987. They attended the same training camp as juniors. And the on-court reunions keep coming on the ATP World Tour, where they have faced off on no less than 30 occasions. They would stand on opposite sides of the net seven times alone in 2015, always in pressure-filled situations.

“There is only week difference between us,” said Djokovic. “Very similar game and very similar role in professional tennis. So I think that’s what makes it very special.

“He has a winning mindset,” added Djokovic of Murray. “He’s a great fighter, great competitor and somebody that commits to this sport. You can see that on a daily basis. He has a great team of people around him. He puts a lot of hours in the practice, gym and so forth. It pays off. I know him for a long time, so it’s great we are able to challenge each other.”

Murray would push Djokovic to deciding sets in Melbourne, Miami and Roland Garros, but won just one game in those three sets, despite being one of fittest players in the game. The Scot would score the ATP Masters 1000 title in Montreal, snapping a two-year, eight-match losing streak against the Serb, but Djokovic would up his FedEx ATP Head2Head advantage to 21-9, including trophies at the Australian Open, Miami Open and the BNP Paribas Masters.

Djokovic’s best-in-the-business inner-drive was perhaps best seen during their five-set battle at Roland Garros, a more-than-three-hour drama the outcome of which was delayed by fading light, rain and hail. Having let a comfortable two-set lead slip away, the 28-year-old refused to cave, winning seven-of-seven net points in the decisive fifth set and denying his opponent even a single break-point opportunity.

Despite the competitive nature of their relationship, Murray insists the two are still good friends.

“I have a lot of respect for Novak as a tennis player,” he observed. “I’ve known him since we were 12, 13 years old. It’s tough to be extremely close when you’re playing in huge matches against each other on a regular basis. That’s normal. But we get on absolutely fine. We were playing basketball together the other day. I get on well with Novak.”

 “When you watch his game, he hits the ball well off both sides,” Murray observed. “He serves well, returns well. He’s a very, very good athlete — very good endurance, as well. There’s not many holes in his game. When maybe one shot for him is off during a match, he can hit all of the other ones well and make up for that, too. There’s a lot of things that he does very well on the court. That’s why he’s been No.1 in the world for a while now.”

The pivotal doubles rubber of the Davis Cup Final between Belgium and Great Britain is tied one set-all. Andy and Jamie Murray took the first set 6-4, while Steve Darcis and David Goffin won the second set by the same score.

The winning team will move within one point of the Davis Cup title after the two countries split singles wins on Friday.

They say it’s not how you start, it’s how you finish.

That has been Daniel Munoz-de la Nava‘s mantra this week at the ATP Challenger Tour Finals. The Spaniard, who dropped his opening round robin match in Group A to Inigo Cervantes on Wednesday, qualified for the semi-finals with a 4-6, 6-3, 6-2 win over Paolo Lorenzi.

A battle of 33-year-old veterans, Munoz-de la Nava exorcised his demons against Lorenzi having dropped five consecutive matches in their FedEx ATP Head2Head series since 2009. The father of two is projected to rise to a career-high position of No. 80 in the Emirates ATP Rankings with the win.

Top seed and World No. 68 Lorenzi was eliminated from semi-final contention with the loss and finishes another successful season with a 43-13 record.

In the other Group A matchup, fifth seed Cervantes capped an undefeated round robin campaign, downing Farrukh Dustov 6-3, 6-3 in one hour and 18 minutes. He fired seven aces and did not face a break point. Cervantes remains the 2015 match wins leader with a 48-20 win-loss mark, pulling into a tie for fourth place in the all-time list of most victories in a season.

Meanwhile, Guilherme Clezar qualified for the semi-finals once again, streaking past Radu Albot 6-2, 6-4. The Brazilian home hope was a suprise finalist last year and will look to exact revenge on Cervantes when the pair square off on Saturday. The second place finisher in Group B, Clezar lost to Cervantes in straight sets last week in Montevideo.

Watch Clezar hot shot

“I have great memories from last year,” said Clezar. “The crowd gave me a lot of support today and that is always a great motivation for a player, to be able to feel everyone behind you. I’ve playing Challengers the whole year, I didn’t lose many matches to players with a lower ranking than mine. My level as a Top 200 player is established. I just need to win more matches.

“The situation is different from Montevideo. It was raining there, the serves weren’t going that fast. [Cervantes] is someone that counter-attacks really well. I hope the serve can make a difference and my balls can go faster. The conditions here suit me more.”

The nightcap at the Pinheiros Club featured a meeting between a 2-0 Guido Pella and 0-2 Marco Cecchinato. Already guaranteed a spot in the last four, Pella’s Sao Paulo campaign would come to a heartbreaking abrupt end as the World No. 76 Argentine retired with a torn right adductor. It was the 2012 champion’s second leg muscle tear in three years after suffering a torn hamstring at Wimbledon 2013. He led Cecchinato 6-1, 1-0 when the injury occurred.

Pella, who was slated to face Munoz-de la Nava in the semi-finals, concedes the walkover to the Spaniard, who advances to the title match.

Continuing our Season In Review Series, ATPWorldTour.com revisits the fiercest rivalries of 2015. Today we feature Novak Djokovic vs. Stan Wawrinka:

Novak Djokovic may have claimed three of four FedEx ATP Head2Head match-ups with Stan Wawrinka in 2015, but the Swiss proved anything but a pushover. In their first meeting, Wawrinka extended the World No. 1 to five sets at the Australian Open — the third straight year they went the distance at Melbourne Park. Though the semi-final would feature a combined 118 unforced errors and 12 service breaks, Wawrinka out-aced his opponent 10-5 and collected 42 winners to 27.

Then, at Roland Garros, Wawrinka would pull off a historic 4-6, 6-4, 6-3, 6-4 upset.

Despite the fact that Wawrinka kept him from completing both a calendar year and career Slam, Djokovic says it’s a friendship unlike any other.

“I feel like I have a very special relationship with Stan, I think like no other top player, honestly,” he said. “I do appreciate that. I do enjoy that good relationship we have. I think that was strengthened even more after the Roland Garros final.”

It was the second time Wawrinka had defeated the Serb on his way to a Grand Slam title.

“This one is really special, for sure, playing Novak here in final, the No. 1 player,” said Wawrinka. “He won almost everything since the beginning of the year. And especially the way I played and the way I finished the match.”

“Of course it was probably the biggest win he ever had and it was disappointing for me to lose that, but I felt like we had that special connection in the end,” Djokovic said. “Look, at the end of the day, we are friends, we are people. Of course we both want to win. When we get on the court, it’s all about business and getting the job done. You do everything that you can to win. But once the match is over, I mean, why not share some nice moments and joke around?”

Djokovic took the next two matches against Wawrinka, in the Cincinnati quarter-finals and Paris semi-finals, upping his FedEx ATP Head2Head advantage to 19-4 overall.

David Goffin completed his first comeback from two sets down in Davis Cup in the opening rubber of the Belgium-Great Britain final tie on Friday. The 24-year-old Belgian faced stiff resistance from 20-year-old Kyle Edmund before prevailing 3-6, 1-6, 6-2, 6-1, 6-0 on an indoor clay court in the Belgian city of Ghent.

Edmund, making his Davis Cup debut, took early control of the match. The No. 100 in the Emirates ATP Rankings put his serve-forehand combination to good use and powered his way to a two-set lead after 70 minutes of play.

Goffin, ranked No. 16, then found his rhythm, taking advantage of the home support to sweep the next three sets in 90 minutes. He broke the Brit nine times in the last three sets (10/19 total). Meanwhile, Edmund broke serve six times in the first three sets, but did not get a break opportunity in the final two sets as Goffin cruised to the finish line.

“He played every forehand really heavy from the beginning,” Goffin said during the post-match on-court interview. “It was tough for me to find my timing on the baseline. I knew I needed to take my chance, and I did well to finish the match quickly in the fourth and fifth sets.

“I wanted to start the match by hitting some balls from the baseline to gain confidence,” Goffin added. “It didn’t work because of how aggressively [Edmund] started. That’s why he won the first two sets, but I’m really happy with the way I turned it around. The atmosphere here is just amazing. I have never played in front of a crowd like this.”

In the second rubber, Belgium’s Reuben Bemelmans will take on World No. 2 Andy Murray.
