The ATP World Tour announced the final list with the participants in the main draw for Garanti Koza Sofia Open’s second edition. The tournament will be held in “Arena Armeec” in the Bulgarian capital 5-12 February 2017.

The hosts and organisers are expecting extremely strong competition in February. The Sofia field includes 11 players in the Top 50 of the Emirates ATP Rankings: Dominic Thiem (No. 8), David Goffin (No. 11), Roberto Bautista Agut (No. 14), Bulgarian star Grigor Dimitrov (No. 17), Viktor Troicki (No. 29), Philipp Kohlschreiber (No. 32), Gilles Muller (No. 34), Martin Klizan (No. 35), Marcos Baghdatis (No. 36), Nicolas Almagro (No. 44) and Andrey Kuznetsov (No. 46).

“It will be a really world-class tournament and the fans will enjoy great tennis throughout the whole week in Sofia,” said the tournament director Paul McNamee.

The draw will include 21 direct entries, along with three wild cards and four qualifiers. Included in this field are the four semi-finalists from last year’s inaugural tournament: champion Bautista Agut, runner-up Troicki, and semi-finalists Muller and Klizan.

Two former Top 10 players – Marcos Baghdatis and Nicolas Almagro, will make their debut in Sofia in 2017.

Baghdatis reached a career-high No. 8 in the Emirates ATP Rankings in August 2006, the same year he reached the Australian Open final (l. to Federer). The 31-years old owns four ATP World Tour trophies from 13 finals. The Spaniard Almagro climbed to No. 9 in the rankings in May 2011. He owns 13 titles.

The scoring system in tennis produces a powerful paradox where you can improve on a successful season even by winning fewer points per match on average.

Players want to win every point, but only a slim majority is needed for victory. The stats sheets suggest that just a handful of points make a real difference in a match.

Take for example Grigor Dimitrov’s resurgence this season.

The 25-year-old Bulgarian had his second best year on the ATP World Tour, going 39-27 to improve his year-end Emirates ATP Ranking from No. 28 in 2015, to No. 17 in 2016. Surely, winning more points per match propelled this jump in the rankings. The answer? Yes and no.

An Infosys ATP Beyond The Numbers analysis of Dimitrov’s return to the Top 20 by 2016’s end makes you do a double-take when you look at his key metrics. The following table compares his 2015 and 2016 seasons, which shows improvement in all areas except average points won:

These numbers produce three main take-aways for players at all levels of the game on how to improve their own performance:

1. Razor-Thin Margins

In 2016, Dimitrov tipped a 50-50 battle with his opponents a mere 1.2 percentage points in his favor. When you look at the flip side of this dynamic, he averaged losing 49 of every 100 points in regaining a coveted spot in the Top 20. An analysis of the ATP Stats LEADERBOARDS shows the Bulgarian clinching those key points in his return game.

Total Service Points Won
2015 = 66.3 per cent
2016 = 65.2 per cent

Total Return Points Won
2015 = 37.1 per cent
2016 = 37.7 per cent

2. All Points Do Not Weigh The Same

Saving break points was a key metric for the Bulgarian in adding six more matches to his win column in 2016 over 2015. Making more first serves in the Ad court on break point, where they occur at about a 3:1 ratio to the Deuce court, was a significant contributor.

3. Head vs Heart

Your heart says try to win every point you play, so your head needs to understand the reality of a stats sheet, which says the opposite. We play a game of percentages, not perfection. Losing is going to happen a lot, and staying positive against the natural forces of adversity and disappointment is as important as any dynamic in a match.

Just weeks away from his return, Roger Federer said on Friday that he’s feeling rejuvenated and is eager to come back to tour-level competition after missing half of the 2016 season.

Federer, speaking with reporters on a conference call, said he’s played “very well” in practice matches with fellow ATP World Tour pros Lucas Pouille of France, Borna Coric of Croatia and Damir Dzumhur of Bosnia-Herzegovina. Federer also said he doesn’t regret sitting out six months of the season. The Swiss legend last played in July at the Wimbledon semi-finals (l. to Raonic).

“I do believe it could be very beneficial for the future of my tennis career that I’ve had this six-month layoff,” Federer said. “I feel rejuvenated, refreshed. Maybe mentally I needed this rest more than I thought I would. Maybe also my body needed a rest more than I thought I would.”

The 88-time tour-level titlist had never taken off so much as few weeks in a season before this year. But 2016 was far from a regular campaign for the 35-year-old father of four.

In February, for the first time in Federer’s career, he had to undergo surgery. A day after losing to Novak Djokovic in the Australian Open semi-finals, Federer tore a meniscus in his left knee while preparing a bath for his twin girls. The right-hander returned to competition two months later, in Monte-Carlo, and, the following month, played the Internazionali BNL d’Italia in Rome.

But Federer then missed another month of the season before making his return on the grass in Stuttgart. He’d play only two more tournaments, including Wimbledon, before later announcing he wouldn’t play again until 2017.

“It was really about taking a tough decision to say, ‘I give myself time, I deserve to give myself time.’ I take six months off in a 20-year career, it’s OK. If you look at six months off in a 12-month season it sounds like there’s no chance I’m ever going to take six months off,” Federer said. “But I tried to look at the big picture. At least one thing I know now, let’s say the knee won’t be good, I have no regrets. I feel I did everything this year to get my body back in shape and now only time can tell.”

Resting for so long assured Federer that he wouldn’t need a second surgery on his left knee. “That for me was No. 1 and crucial. I just needed it to rest really,” he said.

After Wimbledon, he tried to play again in August but decided against seriously testing his knee. “I played again, very quick. There was a bit of a reaction in the knee and that’s when you realize … we knew it was too early,” he said.

Last month, Federer took a couple weeks off before resuming training for 2017. “The last six weeks for me have been crucial and obviously the last two weeks in November when I came back from vacation were really important for me to see how much load I could put on the leg,” Federer said. “Very quickly we realized at the end of November, early December, I was not at 100 per cent yet, let’s be honest, because you always need more time, more reassurance. But things went very well. I didn’t have any setbacks. In the end it all worked out according to plan.”

The time off had upsides as well. “It was great to spend more quality time with the kids, or me with more energy rather than having to worry, ‘Careful, I have a match tomorrow’ or ‘I need to go to bed’ or in the morning ‘Don’t wake me up’ kind of thing because daddy needs to sleep a little bit,” Federer said.

Federer, who has won 24 ATP World Tour Masters 1000 titles and 17 Grand Slam crowns, said he thinks his 18^th Grand Slam title could come next season. He will make his return to tour-level competition at the Australian Open, which starts 16 January.

“I think I’ve been awfully close the last few years but that doesn’t count because it wasn’t winning,” Federer said. “Time will tell if it’s going to be possible or not.”

Former Wimbledon doubles champion Horia Tecau is now a published author. The Romanian wrote a children’s book titled, ‘Viata in ritm de tenis’, translated in English to ‘Life in the rhythm of tennis’, to show children the importance of sports and reading.

The 110-page book encourages children to pursue their dreams through hard work and how to persevere through life’s challenges. “It’s full of lessons that I’ve learned through my tennis experiences,” Tecau said.

Buy The Book

Tecau provided space in the book for children to write their own dreams as well. He launched the book with about 300 kids on 12 December in Bucharest.

The 31-year-old Tecau has won 29 tour-level doubles titles, including 2015 Wimbledon, 2015 Barclays ATP World Tour Finals and two ATP World Tour Masters 1000 tournaments (Cincinnati, 2012; Madrid, 2016). He and Jean-Julien Rojer finished as the 2015 year-end No. 1 in the Emirates ATP Doubles Team Rankings.

Next November, the ATP World Tour’s brightest young stars will take the stage in Milan for the Next Gen ATP Finals. Billed as the ‘Next Generation’ during the campaign launch this past March in Indian Wells, this group of players unleashed their potential in 2016.

In total, 22 players aged 21 and under finished in the Top 200 of the Emirates ATP Rankings, including eight inside the Top 100. Continuing our season in review series, we look back on the 2016 campaigns of the top NextGen players.

No. 13 Nick Kyrgios (21 years, 7 months)
The Australian clinched a trio of titles in 2016 to place fifth among tour leaders behind Andy Murray (9), Novak Djokovic (7), Dominic Thiem (4) and Stan Wawrinka (4). Kyrgios held all 47 service games en route to his first title in Marseille, where he defeated No. 10 Richard Gasquet and No. 8 Tomas Berdych – two of his six victories against Top 10 players this season. He dethroned three-time defending champion John Isner at the BB&T Atlanta Open in August, and followed with the ATP World Tour 500 crown in Tokyo, where he rallied to defeat David Goffin in the final. Kyrgios also reached his first ATP World Tour Masters 1000 semi-final in Miami, helping him finish with 39 match wins and a career-high No. 13 Emirates ATP Ranking.

No. 24 Alexander Zverev (19 years, 8 months)
With his triumph at the St. Petersburg Open, the 19 year old became the youngest player to win an ATP World Tour title since Kei Nishikori and Marin Cilic in 2008. He also became the first teen since Boris Becker in 1986 to defeat three Top 10 players in succession (d. No. 9 Berdych, No. 3 Wawrinka and No. 10 Thiem). Zverev, the 2015 ATP Star of Tomorrow presented by Emirates, reached two other finals – on clay in Nice (l. to Thiem) and on grass in Halle, where he upended eight-time champion Roger Federer in the semi-finals. Zverev reached four other semi-finals – Montpellier, Munich, Washington and Stockholm – finishing his campaign with 44 match wins, which was 10th among tour leaders (tied with Monfils). Zverev rose from a year-end No. 83 Emirates ATP Ranking in 2015 to World No. 20 by October.

No. 45 Kyle Edmund (21 years, 11 months)
From a No. 85 Emirates ATP Ranking going into the US Open, Edmund rose to a career-high No. 40 in October. At Flushing Meadows, he defeated No. 15 Richard Gasquet and Americans Ernesto Escobedo and John Isner before falling to No. 1 Novak Djokovic. Edmund broke into the Top 50 after reaching the Beijing quarter-finals as a qualifier (l. to Murray) and into the Top 40 after making his first ATP World Tour semi-final in Antwerp (l. to Gasquet). Ranked just outside the Top 100 to start the 2016 season, the Brit advanced to his first tour-level quarter-final in Doha as a qualifier in the opening week of the season (l. to Berdych). He also won a pair of ATP Challenger Tour titles in Dallas and Rome, and followed with a quarter-final showing at The Queen’s Club (l. to Murray).

No. 48 Borna Coric (20 years, 1 month)
Though no longer the youngest player in the Top 50 of the Emirates ATP Rankings, the 20-year-old Coric still enjoyed a couple age-related distinctions in 2016. In Chennai during the first week of the season, he became the first teenager to play in an ATP World Tour final since fellow Croatian Marin Cilic in 2008. Coric, the 2014 ATP Star of Tomorrow presented by Emirates, followed with another runner-up showing in Marrakech (l. to Delbonis). In Cincinnati this summer, Coric became the youngest ATP World Tour Masters 1000 quarter-finalist since Novak Djokovic in 2006 as he defeated Benoit Paire, Nick Kyrgios and No. 5 Rafael Nadal in succession. Though his season was cut short a month later when he underwent right knee surgery, Coric still finished inside the Top 50 for a second straight year.

No. 53 Karen Khachanov (20 years, 7 months)
The 20 year old joined Kyrgios and Zverev as one of three first-time winners from the group of NextGen stars in 2016, rising from a No. 101 Emirates ATP Ranking to No. 55 in the space of a week. At the inaugural Chengdu Open, Khachanov knocked out four seeded players, beating Joao Sousa, Feliciano Lopez and Viktor Troicki in straight sets before capping his week with a 6-7(4), 7-6(3), 6-3 comeback against Albert Ramos-Vinolas in the final. Only four months earlier, Khachanov had broken into the Top 100 after lifting his second ATP Challenger Tour trophy. He made a winning Grand Slam main draw debut as a qualifier at the US Open and finished his breakthrough season with a quarter-final result in Vienna.

No. 76 Taylor Fritz (19 years, 1 month)
The American followed in Borna Coric and Alexander Zverev’s footsteps this year, finishing as the youngest player in the Top 100 to be named the ATP Star of Tomorrow presented by Emirates. Fritz, who celebrated his 19th birthday at the end of the October, rose from No. 694 in October 2015 to the Top 100 by the end of February. Following success on the ATP Challenger Tour, where he claimed three titles from four finals, Fritz became the youngest finalist on the ATP World Tour since 2008 when he finished runner-up at the Memphis Open – only his third tour-level event. The California native won 15 tour-level matches and reached a career-high No. 53 in the Emirates ATP Rankings in August.
