US OPEN champion Jamie Murray says his doubles chemistry with Bruno Soares is even better than with his brother Andy.

Murray and Soares won their second grand slam title of the year on Saturday as they beat Spain's Pablo Carreno Busta and Guillermo Garcia-Lopez in Flushing Meadows.

The British-Brazilian duo sealed their first major triumph at the Australian Open in January and their success in New York means they have a chance of finishing 2016 as the number one partnership in the world.

Murray now turns his attention to Britain's Davis Cup semi-final against Argentina on Friday, when he is likely to play with younger brother Andy in the doubles rubber.

The siblings led Britain to Davis Cup glory last year for the first time in 79 years but Jamie believes his partnership with Soares is perhaps even stronger.

"It probably is easier to play with Bruno, like we talk more," Murray said.

"Andy's a great player. But I think Bruno and I are with each other every day. We are working on our games and communicating all the time.

"I find it easy to do that with Bruno. Obviously sometimes with Andy it's not always so easy because great players, they do things the way they do.

"If I kind of come in and start saying, 'I think you need to serve there or hit your return there', they are not used to hearing that. That can be a bit problematic sometimes.

"I think for me and Bruno we are kind of on an even keel and both have the same goal."

Murray linked up with Soares at the start of the year after splitting with Australian John Peers, with whom he had reached consecutive grand slam finals but lost at the final hurdle.

Soares brings baseline stability to Murray's brilliance at the net and the Scot said he hopes their partnership will continue.

"Yeah, of course," Murray said, before Soares added with a smile: "I hope so, I can't do much more to keep him with me."

Murray continued: "Look, we had the best year of our career, whatever way you look at it.

"Neither of us had won a grand slam before and then we came together and we have won two. So yeah of course, I could never disagree with that."

Murray becomes the first British player to win the US Open doubles since Roger Taylor in 1972 and Soares is the first ever from the Brazil to lift the trophy.

They have endured disappointments, however, too, most notably at Wimbledon where they lost in the third round and, separately, at the Olympics. Jamie lost in the first round in Rio with Andy, while Soares was beaten in the quarter-finals.

"We have been good friends for a long time, me and Jamie. We get along super well," Soares said.

"For me, it's very important to get along off court. I can't do this well with someone that I don't get along well with.

"We have had an amazing year but we lost sometimes, some tough ones and with match points.

"You've got to be able to go to dinner with the guy after a tough loss and talk like friends. We get special moments like this, but we have brutal moments as well so it's impossible to do that without a friend."

Meanwhile, Angelique Kerber insists she can cope with the pressure of being US Open champion and world number one.

Kerber outlasted Karolina Pliskova in the final at Flushing Meadows on Saturday to clinch her second grand slam title of the year, after winning her first at the Australian Open in January.

The 28-year-old also climbs above Serena Williams on Monday to become world number one, with the American's 186-week reign at the top ended by her defeat to Pliskova in the semi-finals.

Caroline Wozniacki, who lost to Kerber in the last four, said her opponent's success would put "a target on her back", but the German is confident she can handle the pressure.

"I'm ready to have this pressure on my shoulders," Kerber said.

"I think I get used to all of this, especially after my first grand slam in Australia. I had so much pressure after the title.

"To be number one of course now everybody will try to beat me and they have nothing to lose. I will try to take this challenge because it will be a little bit of a new situation for me.

"But in the end, I was always practising and working hard to be number one, now I can also take the next step and try to stay there as long as I can."

If Williams can overcome a knee injury, the 22-time major champion could reclaim top spot this autumn given she has very few ranking points to defend after hardly featuring at the end of last year.

Nonetheless, Kerber has emerged as a legitimate rival to the 34-year-old's dominance, having become the first woman, apart from Williams, to win two grand slams in a calendar year since Justine Henin in 2007.

Williams was beaten by Kerber in the Australian Open final, lost to Garbine Muguruza in the French Open final, beat Kerber to win Wimbledon, before succumbing to Pliskova in New York.

"The younger generation is definitely catching up," 18-time grand slam champion Martina Navratilova said.

"To me, the biggest surprise was Serena lost the two finals at slams and then a semi-final. Usually in years past she gets more caught out in the first week, not the second week.

"People are maybe feeling more confident now. I think Kerber set it up. Once she beat Serena in Australia, everybody thought, 'Oh, we have a chance'."

Kerber is the oldest player to become world number one for the first time but the likes of Williams, her sister Venus, Roger Federer and Stan Wawrinka are proving players can now challenge for major titles well into their thirties.

It means Kerber has a realistic chance of hoisting more grand slam trophies in the future but she insists Williams is still the player to beat.

"Serena, for me, is one of the best players in the world. She is a great person and a great champion," Kerber said.

"For me, I'm trying to go my own way and trying to enjoy now every single moment with my second grand slam.

"I'm really excited because I'm seeing as well a lot of new and good players on tour.

"They are playing great tennis, so let's see what happens and how they will play in the next few tournaments and the next grand slams."

As Pliskova blazed her final forehand long after two hours and eight minutes, Kerber fell on her back, cupped her hands over her mouth and held her arms aloft.

Pliskova walked around the net to embrace the victor, who then climbed up to the players' box to hug her mother, team and coach, Torben Beltz.

The success caps a superb 12 months for Kerber, who clinched her first major title at the Australian Open in January, reached the Wimbledon final and won an Olympic silver medal.

Pliskova's victory over Williams on Thursday also ensures the 28-year-old will become world number one on Monday and the oldest ever woman to take top spot for the first time.

An emotional Kerber said on court: "It's just amazing. I won my second grand slam in one year.

"It's the best year in my career and actually just incredible. Being world number one means a lot to me.

"When I was a kid I was always dreaming of being number one player in the world and winning grand slams.

"Today I won my second grand slam and I will be number one on Monday. All my dreams came true this year."

Pliskova had never gone past the third round of a major tournament before but after beating Kerber to win the title in Cincinnati last month, she pushed her opponent all the way again.

The world number 11, who will rise to sixth, ultimately came up short in the decider, however, as Kerber's experience and stamina proved decisive.

"I found out I can play my best tennis on the biggest stages against the top players," Pliskova said.

Kerber takes home the cheque for 3.5million US dollars and becomes the first woman, other than Williams, to win two grand slams in a year since Justine Henin in 2007. Her rivalry with the American may be just beginning.

Pliskova looked like a bag of nerves early on as she opened up with a double fault before wafting a forehand volley wide when she had the whole court at her mercy.

Kerber was more composed and in the same game she seized the break when Pliskova's drop-shot drifted wide.

Pliskova had been aggressive against Williams, shortening the rallies with aggression from the baseline but her groundshots were too cautious early on.

Kerber, meanwhile, was sticking to her strengths, chasing and counter-attacking, and when Pliskova double faulted to hand her set point, she converted by hunting down a drop-shot and brilliantly chipping it into the corner.

At the start of the second, Pliskova squandered a break point with a sloppy forehand and as she sat down in her chair at the change-over, she swatted away a back-up racket in frustration.

The momentum had shifted, however, and when another chance arrived at 3-3 she took it.

Kerber should have put away a short forehand and Pliskova reacted, patting over a sumptuous lob that landed square on the line. Pliskova roared in celebration while Kerber was left applauding her racket.

Soon, Pliskova was fist pumping again as her serve, now firing on all cylinders, closed out the set, the first Kerber had lost all tournament.

Kerber was suddenly on the ropes, unable to find an answer to her opponent's power, and when Pliskova broke again at the start of the third, the favourite was not clapping her racket but flinging it into the ground.

There was more drama to come, however, as a resilient Kerber regained her composure to break back for 3-3 and three games later, she landed the knock-out blow.

Under pressure, Pliskova's serve finally failed her and when her final forehand sailed long, Kerber's success was complete.
