Britain's women's number 1 Johanna Konta has broken into the world's top 30, following her stunning performances of late - which included reaching the last four of the Australian Open last month.
Konta has exploded has onto the scene in the last year, taking scalps of many of the best players on the WTA tour, and has now been propelled up the rankings 19 places, leaping from 47 to 28.
2015 the breakthrough year
It was only at the conclusion of 2014 that the Konta sat in the lowly position of 150. Having occupied the top 100 in the past, with a previous high ranking of 89, the Brit slipped down the ladder after failing to consistently garner WTA tour points.
However, 2015 was the year in which she truly announced her arrival. After playing in her first major outside of Wimbledon, Konta lost her first round match at the French Open against Czech Denisa Allertova. She then went on to reach the quarter-finals of both the Nottingham and Eastbourne warm-up events to SW19.
Konta again failed to make it past the first hurdle at Wimbledon - albeit this time versus former champion Maria Sharapova. It was the fourth successive year that the Briton had failed to make the second round since 2012.
US Open success lays the foundation
As Konta entered the hard court season, she regained her singles crown in Vancouver, beating Kirsten Flipkens of Belgium to re-enter the top 100.
As the US Open arrived, Konta began to make herself known. After only her second Grand Slam victory in the first round versus Louisa Chirico, the Brit achieved her first top 10 scalp as she beat Garbiñe Muguruza. In beating Andrea Petkovic, Konta then was eliminated by two-time Wimbledon champion Petra Kvitová in the last 16.
Still, her run at Flushing Meadows did enough to catapult her up the standings to no. 58 in the world.
Historic semi-final
Konta, now 24, was establishing herself as a rising force in the women's game. In the weeks to follow, the Sydney-born the Briton beat world number two Simona Halep and Grand Slam winner Victoria Azarenka - after the Belarusian retired during their Wuhan Open match. Konta's exploits lifted her into the top 50 for the first time, overtaking Heather Watson as British number one.
After qualifying for the Australian Open, Konta went on the sort of run future champions are made of. After yet another top 10 victory over eighth-seed Venus Williams on Rod Laver Arena, Konta had reached the second round.
The Brit went on to avenge her defeat to Allertova at Roland Garros before beating both seed Ekaterina Makarova and surprise package Zheng Shuai to reach a historic slam semi-final for British tennis.
Konta's loss to eventual champion Angelique Kerber was testament to the huge progress made in a the last 12 months. Now inside the top 30, Konta will be seeded for the French Open, should she stay in it until the event in late May.
As 2016 begins, it could be a year that promises much for the Brit.
