Four-time champion Roger Federer has withdrawn from the BNP Paribas Open in Indian Wells next month as he continues to rehab from knee surgery. Federer underwent arthroscopic surgery on his knee February 3 in Switzerland and only returned to the practice court this past Tuesday.

On his Facebook page, Federer wrote: “The rehab for my knee is going really well! I have now had a lot of great practices on the court and in the gym. As it is a long year, I don’t want to push it too hard and come back too soon. Thus, I will unfortunately not be able to make it back in time for the great event in Indian Wells but I do plan on playing in the desert next year.

“After consultation with my team, I have decided to enter the Monte-Carlo Rolex Masters. Thanks for the support and I will see you back on tour soon.”

Federer finished runner-up to Novak Djokovic the past two years in Indian Wells, where he last won the title in 2012. The Swiss also won three consecutive titles in the Californian desert from 2004-06. Since making his debut in 2001, Federer has made 15 consecutive appearances in Indian Wells, where he boasts a 52-11 record.

Federer suffered a torn meniscus one day after falling to Novak Djokovic in the semi-finals of the Australian Open in late January.

Former World No. 8 Marcos Baghdatis is through to his biggest ATP World Tour final since 2010 after defeating Feliciano Lopez 3-6, 7-6(1), 6-1 on Friday in the semi-finals of the Dubai Duty Free Tennis Championships.

The Cypriot is through to his first ATP World Tour 500 final since finishing runner-up at the Citi Open in Washington six years ago.

Looking to win his fifth ATP World Tour title (4-8 finals record), Baghdatis will face second seed Stan Wawrinka on Saturday. The right-hander will need to overturn a 0-5 FedEx ATP Head2Head record against Wawrinka.

“It’s amazing,” said Baghdatis. “It’s been a long road for me the past three, four years. It’s all about fighting, getting back to where I want to be. Last year we set some goals to be Top 50 with my team. I achieved that.

“Now I’m moving forward. I think I have still a lot to improve on, but the most important thing is health-wise I’m very, very good. I don’t have any injuries or the health problems that I had. I’m happy I’m back on the court and winning. It’s a nice feeling. I’m going to work even harder so it continues.

“I have definitely thought of retiring. That’s where my wife (former WTA player Karolina Sprem) was there and was very strong, made me take the right decisions. My agent, my parents, my team around me, we saw the light at the end of the tunnel.”

The 30-year-old Baghdatis was up against it facing the sixth-seeded Lopez, but turned around a set and a break deficit to prevail in just over two hours.

“He was the better player today I think the first two sets,” said Baghdatis. “He couldn’t hold his nerves. End of the second he was a break up at 4-3, and serving with new balls he couldn’t hold his nerves.

“The crowd helped me amazingly there and I found a way to fight in the second and win it. I think I played an unbelievable tie-break, very solid, returned very well, served very well.

“Then I started to get momentum in the third. And once I got the break, then held after being down 0/40 on my serve at 2-1, then everything went pretty smooth.”

Pablo Carreno Busta ended lucky loser Roberto Carballes Baena’s campaign in Sao Paulo on Friday with a 6-0, 6-3 win over his fellow Spaniard to reach the semi-finals of the Brasil Open. Carreno Busta capitalised on all four of his break point chances and faced no break points in the 51-minute victory. He will next face the winner of fourth seed Federico Delbonis and Inigo Cervantes.

The 24-year-old Carreno Busta reached his first ATP World Tour singles semi-final since Estoril last year (l. to Kyrgios) and is bidding to reach his first tour-level final.

Later, Dusan Lajovic takes on Gastao Elias for a spot in the other semi-final against third seed Pablo Cuevas or Thiago Monteiro.

World No. 4 Stan Wawrinka will contest his second ATP World Tour final of the season at the Dubai Duty Free Tennis Championships when he takes on either Feliciano Lopez or Marcos Baghdatis.

The Swiss won his semi-final match on Friday when Nick Kyrgios was forced to retire from the contest with a back injury. Wawrinka was leading 6-4, 3-0.

“For sure if you look from the beginning of the week I was not playing great at all,” said Wawrinka, who was two points from defeat in the first round against Sergiy Stakhovsky. “But that’s when I can still improve and I’m happy I did this week – not playing some great tennis, frustrated during matches, but still fighting and trying to find solutions to win more matches during the week to play better.”

The 30-year-old Wawrinka is back in Dubai for the first time since first-round exits in 2006 and 2008. The Lausanne native, now a two-time Grand Slam champion, is looking to win his 13th tour-level title and second of the season. In the first week of his 2016 ATP World Tour campaign, Wawrinka beat teenager Borna Coric to win the Chennai crown.

Wawrinka is on an eight-match winning streak in finals and has a 12-9 record.

Kyrgios was coming off his first ATP World Tour title in Marseille, where he defeated Marin Cilic in the final. “I couldn’t really serve anywhere near my full capacity today,” explained the injured Kyrgios. “He was playing great, anyway. He was playing really aggressive off the second shot of his serve.”

They are renowned for having among the finest single-handed backhand’s in the men’s game and on Thursday, Dominic Thiem emerged triumphant in the battle of two of the ATP World Tour’s brightest prospects, defeating Grigor Dimitrov 7-5, 6-2 in the Abierto Mexicano Telcel quarter-finals.

The World No. 15 in the Emirates ATP Rankings reached the semi-finals last week in Rio de Janeiro after capturing his fourth career title in Buenos Aires the week prior. World No. 26 Dimitrov was appearing in his fourth ATP World Tour quarter-final of 2016.

It was the pair’s first FedEx ATP Head2Head encounter and the 22-year-old Austrian made the quicker start of the two, breaking the Bulgarian’s opening service game before relinquishing the break for 2-2.

Seventh seed Dimitrov again faltered on serve at 5-5, allowing the No. 4 seed to serve out the opening set in one hour and two minutes. Thiem started the second set in the same vein as the first, breaking immediately for 1-0 before securing the double break for 5-2. He served out the match to love after one hour and 38 minutes.

“Breaking him in the first game of the second set was maybe the deciding moment of this match,” Thiem said. “The key of this match was to win the first set. I started to play better and better and the momentum swung to my side.

“Of course if you’re a set and a break up … you think you have momentum on your side but there’s still a very long way to go. My opinion is that Grigor is an unbelievable player with a beautiful game. I hope in the near future we are at the top together.”

The win books Thiem a semi-final showdown with either Taylor Fritz or Sam Querrey. “Tomorrow it’s going to be very tough against Fritz or Querrey,” Thiem said.

“They’re both on a run. Of course the biggest goal is to win this tournament but it’s going to be very difficult.”

Bernard Tomic will meet Alexandr Dolgopolov for a place in the Abierto Mexicano Telcel final after both posted straight-sets victories on Thursday. Fifth-seeded Tomic, contesting his fourth quarter-final of the year, landed a narrow 7-5, 7-5 victory against Ukraine’s Illya Marchenko, while Marchenko’s compatriot Dolgopolov easily accounted for Robin Haase 6-3, 6-3.

Tomic managed to break five times, winning 59 per cent of points on his 28-year-old opponent’s second serve. The World No. 21 in the Emirates ATP Rankings was appearing in the Acapulco quarter-finals for the second year in a row having earlier defeated Rajeev Ram and Adrian Mannarino without the loss of a set.

Marchenko was appearing in his eighth ATP World Tour quarter-final and had taken down a pair of American qualifiers in succession, Tommy Paul and Ryan Harrison, before encountering the 23-year-old Tomic. Dolgopolov, coming off an upset of top seed and defending champion David Ferrer, was contesting the quarter-finals at Acapulco for the fourth time. The 27 year old’s one-hour, four-minute result over Dutchman Haase levelled the pair’s FedEx ATP Head2Head series at 2-2.

He will carry confidence into his semi-final against Tomic, having won six of the nine times he has faced the Australian. “I’ll try to do the same as all the other matches I’ve played here,” Dolgopolov said. “I played aggressive here today and that’s what I need to do tomorrow.

“We’ve played a lot of times, he’s a tricky player. He slices well, he plays all around the court, serves well and breaks up your rhythm. I think it will be on my racquet because I risk a bit more than him in general.”

As Roger Federer’s comeback plans after knee surgery gather momentum, the Swiss great has taken to his website to thank fans for their outpouring of support. The 34 year old earlier this week shared a photo on social media highlighting his first hit-out on the practice courts since undergoing a right knee arthroscopy to repair a torn meniscus three weeks ago.

Federer posted the thank-you note to his website yesterday. “I would like to send out a heartfelt thank you for all your kind words after my injury and the surgery,” he posted. 

“It was an amazingly positive boost to receive all your cards, letters, presents and posts on the web. It really means a whole lot to me to feel your support in tough times.”

The injury, which occurred the day after his Australian Open semi-final loss to Novak Djokovic, forced Federer to skip the ABN AMRO World Tennis Tournament in Rotterdam and the Dubai Duty Free Tennis Championships in Dubai.

“It is fantastic to be moving and working out again,” he added. “We’re taking it one step at a time, but I’m already really looking forward to getting back onto the court with full energy. Thank you very much again, see you soon.”

Buoyed by the news, Federer’s fans continued their words of encouragement. 

“It is wonderful to see you are able to be so mobile again after your surgery! I am so looking forward to seeing you play again, tennis is just not the same without you. Take care Roger, you mean the world to us,” Wendy_Redrobin of Great Britain posted.

“Dear Roger, thank you very much for your update. It is so good to know you are working out again!” Cecivonne of Ecuador said.

“Dear Roger, come back stronger and fully recuperated. We miss you,” Arevik of Armenia said.

“Thank you Roger for keeping in touch … we are all eager to see you back on court, stronger than ever. Take care,” Chervil of Australia posted.

“So very heartening to hear of your positive progress health wise. Such a relief. Can’t even begin to tell you how it feels not having you around but your jumping pics brought a huge smile to my face as does this message from you! Get better by the minute and see you in action soon!” Sigtias of India said.
