Top seed Rafael Nadal has had his first hit out ahead of his Argentina Open title defence, practising with compatriot David Ferrer in Buenos Aires on Monday.

It was the first look at Nadal in action since his first-round exit to another of his countrymen, Fernando Verdasco, at this year’s Australian Open. The Spaniard downed his good friend Juan Monaco to claim last year’s title in the Argentine capital and the pair could be set for a rematch in the second round provided Tandil native Monaco wins his first match.

“I didn’t like at all the defeat in Australia, but that I cannot solve,” Nadal said. “It was a bad tournament. [It] just did not work out despite having prepared very well. So I’m in Buenos Aires to give my best and try to make a better presentation.

“Every season is different, but with the same purpose to fight in every tournament and finish as high as possible in the ranking. I’m happy to return to Argentina, because every time I left this country I did it with a lot of positive energy. They treat me very well here, like few places in the world.”

World No. 5 Nadal has a first-round bye, while Monaco can set up an eighth FedEx ATP Head2Head meeting with his occasional doubles partner should he get past Italian qualifier, Marco Cecchinato. The pair won the 2015 Doha doubles title together, and finished runners-up at Vina Del Mar in 2013.

“Monaco was injured a long time, so we have to wait if he can eliminate Cecchinato,” Nadal said. “I hope that Juan can win because he is my friend and a victory would benefit him after many days without playing. Anyway, it will be a difficult match for me.”

A tournament record five American teenagers are competing in this year’s Memphis Open presented by ServiceMaster. Overall there are 13 Americans in the 28-player draw, the most in Memphis since 2010 when there were 14.

Taylor Fritz (18), Tommy Paul (18), Frances Tiafoe (18), Michael Mmoh (18) and Jared Donaldson (19) posed together in front of the Racquet Club’s Memphis Open 40^th anniversary  tournament sign. Mmoh and Donaldson qualified on Sunday into the main draw. The other three players are wild cards.

The five American teenagers in the draw surpassed the previous tournament record of four in 1989. That foursome featured future Grand Slam tournament champions Andre Agassi, Michael Chang, Jim Courier and Pete Sampras.

The last time an ATP World Tour tournament featured at least five American teenagers in the main draw was in Stratton Mountain in August 1989 when there were six teenagers: Agassi, Steve Bryan, Chang, Courier, Jared Palmer and Sampras.

Teenager Alexander Zverev was presented with a special award on Monday in Rotterdam, recognising his first year-end Top 100 finish in the Emirates ATP Rankings in 2015.

Receiving his award from ATP Tour Manager, Fernando Sanchez, 18-year-old Zverev said, “It’s a big milestone. To get this award at only 18 years of age is big for me. It’s a really big stepping stone for any tennis player, finishing the year in the Top 100. I feel good. I’ve been playing well the past couple of weeks. Coming into this big tournament, I feel comfortable. I can do well here as well.”

Zverev was named the 2015 Emirates ATP Star of Tomorrow after finishing last season as the youngest player inside the Top 100. The German comes into the ABN AMRO World Tennis Tournament at a career-high World No. 70 after reaching the semi-finals in Montpellier last week (l. to Mathieu).

Zverev will open his campaign at this ATP World Tour 500 indoor hard-court tournament against Canada’s Vasek Pospisil.

Former champion Nicolas Almagro made a strong start to his Argentina Open campaign Monday, beating qualifier Albert Montanes 6-3, 6-3 to reach the second round in Buenos Aires.

In the first meeting between the Spaniards since 2011, Almagro claimed just his second match win of the year after firing 11 aces and saving all four break points faced. He dropped just five points on his first serve (25/30).

The 30-year-old Spaniard, who also finished runner-up to David Ferrer in 2012, improved to 26-9 at the event. He has reached the semi-finals the past three years – 2013 (l. to Wawrinka), 2014 (l. to Ferrer), and 2015 (l. to Monaco).

The former World No. 9, who levelled his FedEx ATP Head2Head record with Montanes at 3-3, is playing his first event since falling in second round of the Australian Open (l. to Thiem). He fell in the first round of Chennai (l. to Pavic) in his only other appearance of 2016.

Buenos Aires local Diego Schwartzman got his campaign off to a winning start with an upset of No.7 seed Alexandr Dolgopolov 5-7, 6-4, 6-3. The 23 year old needed two hours and 10 minutes to defeat the Ukrainian and did so on the back of 11 aces, winning 63 per cent of points on his first serve and 65 per cent on his second serve.

Colombia’s Santiago Giraldo posted a 6-1, 7-5 victory over Spaniard Inigo Cervantes in one hour and 27 minutes. Giraldo converted five of 12 break points on his way to the second round.

Marin Cilic, the 2014 runner-up, fired down 10 aces and won 90 per cent of his first service points to beat Denis Istomin on Monday for a spot in the ABN AMRO World Tennis Tournament second round.

“It was a very close match,” said Cilic. “Denis is the kind of player that can play really, really well, especially indoors. He’s got really good shots from the back of the court. I think it was a strange match today. Both of us were serving extremely well. There were no breaks of serve in the match until the last game. I was threatening a lot in the second set and was close to converting some break opportunities. I had to hang in there mentally. I was moving well and serving well and that was key for me.”

Ivan Dodig saved all four break points he faced to knock out seventh seed Benoit Paire 6-3, 7-6(4) in 90 minutes, while Jiri Vesely hit 11 aces to win an all-Czech clash against Lukas Rosol 6-4, 6-2 in 75 minutes.

Borna Coric made it three from three for the Croats when he made a winning debut against local wild card Thiemo de Bakker. The 19 year old saved 10 set points to secure the opening tiebreak and went on to break in the eighth game of the third set, converting his seventh break point of the match.

“It was a very close match. In the end I was a little bit lucky, but also brave,” Coric said. “I didn’t play very well in my last three tournaments. I didn’t feel very well [on the court]. This was my fresh start. I focused on this match a lot and I did play well in the end. I just knew if I broke at that stage in the third that more or less that would be it. I was really digging in there.”

French qualifier Nicolas Mahut continued his run of form to down Russian Teymuraz Gabashvili 6-4, 7-6(4). The 34 year old hit six aces and won 77 per cent of first serve points to progress in one hour and 51 minutes.

A LOOK BACK
RBC Tennis Championships of Dallas (Dallas, U.S.A.): Coming off an upset defeat to Wu Di in the Maui final, the question for Kyle Edmund in Dallas was whether the Brit would use it as motivation or suffer an immediate letdown. By the end of the week, the answer was clear. Edmund turned in a dominant display on the indoor hard courts of the T Bar M Racquet Club, not dropping a set en route to the title. He would defeat countryman Daniel Evans 6-3, 6-2 on Saturday in just 64 minutes, capturing his fourth ATP Challenger Tour crown. It was just the second ATP Challenger Tour final between two Brits in the past 20 years, with the most recent coming in Nottingham 2005, when Alex Bogdanovic defeated Mark Hilton.

“I haven’t played Dan in a match and whenever you play a new opponent it’s about figuring them out from the start,” Edmund told broadcaster Mike Cation following the match. “I had played a really good match against Tim [Smyczek] and found a good rhythm, so I knew if I could implement that today I’d have a chance. It was played at a different speed, as Dan hits a lot of slices and I knew I had to be patient… As I got into it, I started playing more freely and in the end I was playing some really good tennis.

“Last week was so frustrating because it was a low standard for me. He (Wu Di) was actually playing pretty well in the (windy) conditions and I think I deservedly lost. To come here, from outdoors to indoors, it’s not easy, and everyone was telling me that the courts are quick. But I found I had time to rally here and get my forehand and every match got more comfortable.”

Edmund’s title ended a run of 10 straight years with a home grown champion in Dallas. He beat defending champion Tim Smyczek in the semi-finals. In addition, Great Britain now has nine Challenger titles in the past 13 months after winning just two from 2010 to 2014.

“From last year to this year, I’ve really improved my movement and being more efficient. My serve has gotten better and my forehand has always been a weapon, but now I’m being smarter with it. I’m not hitting winners with every shot and I don’t need to. Those are the big things.

“The good thing about playing Challengers is they are all on live stream, so everyone can watch back at home. My parents and sister have been up at four in the morning and it’s nice that they are so supportive. I want to be playing in the [ATP World Tour] events, but it’s a tough spot now because I have to decide between playing qualies and Challengers where there are big points on offer. It’s getting that balance. Hopefully I can get to that stage where I’m picking a schedule of Tour event and Tour event. That is the ultimate goal.”

Neville-Smith Forest Products Launceston International  (Launceston, Australia): Aussie wild card Blake Mott turned in one of the more improbable title runs in ATP Challenger Tour history, rallying for his first crown 6-7(4), 6-1, 6-2 over Andrey Golubev on Sunday. The 19 year old was at No. 721 in the Emirates ATP Rankings, becoming just the fifth player (since 2000) outside the Top 700 to win a title.

Mott, who will vault nearly 400 spots to a career-high No. 365, had won just three matches at the Challenger level entering the week. He is the second teen titlist this year, joining Happy Valley winner Taylor Fritz, and is the 10th different teenage champion in the past 13 months.
