If only all tournaments were played in London. Jean-Julien Rojer and Horia Tecau would be unstoppable it seems.

Twelve key victories in the English capital in 2015 went a long way to securing the year-end No. 1 spot in the Emirates ATP Doubles Team Rankings for Rojer and Tecau – making them only the third team in the past 13 years to interrupt the Bryans’ reign at the top and ending the Americans’ six-year run.

In their debut season together in 2014, Rojer and Tecau had lifted eight trophies together. It was quite the feat, but the pair knew they could still achieve even more on a bigger stage. And while their tally amounted to ‘just’ three titles in 2015, those triumphs came at Wimbledon (the first Grand Slam title for both), the Barclays ATP World Tour Finals – where they didn’t lose a set in five matches – and at the ATP World Tour 500 tournament in Rotterdam.

Indeed, it was a season where the spoils were largely divided in the doubles game. The four Grand Slam championships were won by different teams, and though Bob and Mike Bryan went major-less for the first time since 2004, they still finished as the No. 2-ranked duo courtesy of six ATP World Tour titles – including three at Masters 1000 level – and a runner-up showing at Roland Garros.

The battle for the team year-end No. 1 went right down to the penultimate match of the season, with four teams still in the hunt at the start of the Barclays ATP World Tour Finals.

The Bryans kept their hopes alive in arguably the best contest of the season as they saved five match points to edge Jamie Murray and John Peers 6-7(5), 7-6(5), 16-14 in a Group Ashe/Smith decider at the Barclays ATP World Tour Finals. But in the subsequent winner-take-all semi-final battle with Rojer/Tecau, it was the Dutch/Romanian pairing who prevailed, sealing the No. 1 ranking and a spot in the final at The O2.

Having notched just two wins between them in three previous visits to The O2, Rojer and Tecau would go on to cap a dream week with victory over Rohan Bopanna and Florin Mergea in the final.

“It’s amazing,” said Tecau. “We were joking that next year we’re only going to play in London! It’s a great city that we enjoy very much. It was a great year, our second year playing together. We improved as a team. We had bigger goals, a better schedule. We’re always trying to improve our games and our partnership. It’s very rewarding to be able to finish the year being able to do all those little things that you’ve worked on – winning this title, being No. 1, having a Grand Slam on our resume.”

“Our big breakthrough came at Wimbledon,” said Rojer. “Having won that match, playing on Centre Court at Wimbledon, it really gave us a lot of confidence for our other goals. One of them was playing at The O2. It’s such a big event and nice arena. There’s a lot of pressure on the court, but it gives us confidence knowing we can overcome these situations. [Everything we’ve achieved this year] is overwhelming. It’s really, really nice.”

The Bryans also lost their grip on the individual No. 1 spot in the Emirates ATP Doubles Rankings for the first time since 2012, with Marcelo Melo finishing top of the pile after a standout season. The Brazilian captured six titles with three different partners, including his first Grand Slam triumph at Roland Garros alongside Ivan Dodig, and went on a 17-match winning streak after the US Open – lifting trophies in Tokyo, Shanghai, Vienna and Paris. He and Dodig were semi-finalists at the year-end championships in London.

“Of course all tennis players dream of being No. 1 and winning a Grand Slam,” said Melo. “So I’m pretty happy I could make it. All of my family, my father and mother, are so proud. It’s really nice for me. This year I had my best results so far. I was a bit surprised to start the season so well, but I realised it was going to be my year.”

Simone Bolelli and Fabio Fognini sprung somewhat of a surprise at the start of the season. The unseeded Italians lit up Melbourne Park as they triumphed at the Australian Open, beating Rojer and Tecau in the semi-finals before overcoming fellow first-time finalists Pierre-Hugues Herbert and Nicolas Mahut in the final. Also runners-up in Indian Wells, Monte-Carlo and Shanghai, they would go on to qualify for the Barclays ATP World Tour Finals for the first time.

“For sure the Australian Open victory is something we always keep in our minds, it was fantastic,” said Fognini.

Bolelli added, “After the win we immediately started thinking about the Barclays ATP World Tour Finals. It was our goal. We made a couple of other very good results this year. Our doubles success helped our confidence in singles too.”

The disappointment of losing the Australian Open final for Herbert and Mahut was forgotten in September when they triumphed at the US Open, becoming the first all-French duo to prevail at Flushing Meadows. It also marked the ninth Grand Slam in a row to have been won by a different men’s doubles team.

“The Australian Open was the first time I had ever won a match at a Grand Slam, and I went on to reach the final with Nicolas. It was all new and great to be part of it,” said Herbert. “The US Open was even bigger. When you’re five years old and you see Grand Slams on TV, you want to be part of it and you work for 15-20 years to have the level to play those kind of tournaments. Then we won it. And it came so fast with Nico. When you realise a childhood dream, it’s amazing and it was the best sensation I’ve had in my whole life.”

Defeat at the US Open marked a second Grand Slam final defeat of the season for Murray and Peers, who had also fallen just short at Wimbledon. The British/Australian pair, who will go their separate ways in 2016, enjoyed a career-best campaign, winning two titles from eight finals and finishing as the fourth best team in the world.

Tim Henman will meet Fernando Gonzalez in Sunday’s Champions Tennis Final at the Royal Albert Hall.

The former British No. 1 booked his place in the showpiece event with a straight-sets win over Younes El Aynaoui. A single break in each set was enough for Henman, who prevailed 6-3 7-5 on Saturday afternoon to top Group A.

Earlier in the week, Fernando Gonzalez came through Group B courtesy of wins over Xavier Malisse and Sebastien Grosjean.

Also on Saturday, Bahrami and McEnroe beat Cash and Pernfors 7-4 in a highly entertaining exhibition doubles match.

Elsewhere, the much-anticipated Tie Break Tens event was launched. In an evening of fast-paced, first-to-ten-point tie breaks, it was 20-year-old Kyle Edmund who emerged victorious.

The Briton beat his compatriot Andy Murray 10-7 in the final. For all of Murray’s considerable defensive capabilities, Edmund’s powerful forehand proved destructive as he avenged a Group stage loss and took home the $250,000 prize.

Elsewhere on Saturday, Champions Tennis saw families able to upgrade to a Family Advantage Package and enjoy over an hour of fun in the Champions Club at the Royal Albert Hall, including Judy Murray’s Miss-Hits.

Continuing our Season In Review Series, ATPWorldTour.com revisits the best ATP World Tour matches of 2015. In today’s countdown we feature Nos. 2-1:

Andy Murray d. Novak Djokovic 6-4, 4-6, 6-3/F/Montreal

Andy Murray acknowledged as much; that “there is no disgrace in losing to” Novak Djokovic, something that the Scotsman experienced on six of seven occasions in 2015, each time in a semi-final or final. But the newly minted year-end World No. 2 in the Emirates ATP Rankings didn’t walk away empty-handed. In fact, his three-hour-long 6-4, 4-6, 6-3 triumph over the Serb for the Montreal title — his 11th career win over a World No. 1 — proved to be one of the most thrilling ATP World Tour matches of the year.

“To win this one was nice, especially the way the match went,” said Murray, who notched his third Rogers Cup title (2009, 2010). “It would have been easy for me to let that one slip away. But I fought well and stayed calm in the important moments of the third set.

“I think I did come up and play aggressively when I needed to — especially in the third set when I was brea kpoints down,” he continued. “I finished a couple of points at the net, got some free points on my first serve, as well. I would say the margins were so fine. I felt like I played as aggressively as I could.”

With Murray surging to 3-0 in the deciding set, the Serb regularly looked at his right elbow in discomfort. However, he refused to let go without a fight, surviving three championship points at 2-5 before the Scot closed it out 6-3 on his fifth match point.

Murray’s triumph snapped an eight-match losing streak against Djokovic, who was contesting a career-best ninth straight tour-level final dating back to the Australian Open. He was riding a 12-match winning streak in ATP Masters 1000 finals since falling to Roger Federer in the Cincinnati decider in 2012. He had won his past 30 ATP Masters 1000 matches.

“You never like losing, but any streak comes to an end,” Djokovic confided. “I did fight until the last point and did try my best. That’s something that I take as a positive.”

Murray’s victory marked just his ninth in 28 meetings with Djokovic. He had not beaten him since claiming the Wimbledon final in 2013 and despite the pair being back atop the Emirates ATP Rankings, Djokovic refused to call it the next great rivalry in the men’s game.

“I think we already have a rivalry. It’s not the next. It’s already existing there for many years,” he said. “Andy is deservedly a winner today on the court… He deserved it. He stepped in, played some great shots. Most of all the moments when he needed to, he served very, very well.”

Nick Kyrgios d. Roger Federer 6–7(2), 7–6(5), 7–6(12)/R32/Madrid

It’s not every day you get to take the court with your childhood idol. It’s not every day either that you come away with a dream win. But that’s exactly what Aussie young gun Nick Kyrgios pulled off in the second round at the Mutua Madrid Open, a 6-7(2), 7-6(5), 7-6(12) ATP World Tour Masters 1000-level stunner over Roger Federer, only the second Top-10 win of his career.

“Last night it was a bit tough to get some sleep knowing that I was going out there,” he said. “I’ve been playing well recently on the clay, so I knew I had a good chance to go out there and do well. I stuck to my game and served well and I got the win.”

The 20-year-old from Canberra halted Federer’s quest for a fourth title in Madrid in two hours and 37 minutes. Federer rallied from a break down to take the opening set, but Kyrgios would soon level the match. Neither player faced a break point in the third set, which boiled down to yet another tie-break. The top seed saved five match points before Kyrgios sealed the match in a tie-break, 14-12.

“This is my best win,” said Kyrgios. “He’s proven that he’s the best.  He can play on any surface.  Obviously, he’s the leading Grand Slam winner, done so much for the sport.”

In his first – and so far, only – meeting with Federer, Kyrgios fired 22 aces and won 79 percent of points on his first serve. However, the Aussie shotmaker would be cut down in the next round against John Isner, who fired 20 aces to Kyrgios’ 10.

“He likes the big stage,” said Federer. “He’s got nothing to lose, no fear, and he’s got a great game. He can rely on his serve so much. It keeps him in the match regardless of he how he plays from the baseline. All he needs to do is string a few good shots, a few good points together when it really matters.”

Kyrgios out-aced his veteran opponent 22-16 and won 79 per cent (67 of 85) first-serve points.

“I was definitely thinking about the finish line, which is probably not the greatest thing, especially against Federer,” Kyrgios confided. “He’s going to take advantage of that. But I thought as I was saving match points and he was saving match points, just have to go through your routine and pick a spot on your return, and try and do whatever you can. Probably had plenty to lose out there.  You’ve been out there three hours. You don’t want to lose 7‑6 in the third.”

The ATP Challenger Tour’s finest had their moment in the spotlight during the Barclays ATP World Tour Finals.

Throughout the 2015 season, nine tournaments on the circuit were honoured with 25-year commitment awards and the celebration culminated with a group dinner in London. These events have exemplified a steadfast dedication to growing the game and creating a strong foundation for players to develop their skills at the Challenger level.

“The ATP Challenger Tour is the bedrock of men’s professional tennis,” said ATP Executive Chairman and President Chris Kermode. “We’re delighted to be able to welcome and show our appreciation to these tournament organisers that have done so much for our sport over the years. The success of the ATP Challenger Tour is critical to the overall health of men’s professional tennis.”

Tournament directors and guests from Cherbourg (France), Furth (Germany), Istanbul (Turkey), San Luis Potosi (Mexico), Segovia (Spain), Sevilla (Spain), Tampere (Finland) and a USTA representative for Aptos and Winnetka were on hand. Many current and former ATP World Tour stars have started their journeys at these tournaments, including Rafael Nadal lifting the Segovia trophy in 2003, Patrick Rafter in Aptos 1993, Robin Soderling in Istanbul 2003 and Grigor Dimitrov in Cherbourg 2011. The tournament in San Luis Potosi is the oldest of the group, having first opened its doors in 1980.

In addition, tournament directors and guests from Braunschweig (Germany) and Genova (Italy) were honoured as co-ATP Challenger of the Year in 2014.

Former World No. 4 James Blake came from behind to beat Younes El Aynaoui 4-6, 6-3, 10-8 in an absorbing Champions Tennis contest at the Royal Albert Hall on Friday evening.

While El Aynaoui, 44, was the steadier of the two players for much of the match, Blake eventually found his rhythm. Some crunching returns and trademark forehands helped turn the tide in his favour and he edged a nail-biting Champions Tie-break on his third match point.

WATCH: Point of the Day
