In a solid day for the home favourites on Monday, Federico Delbonis and Leonardo Mayer are through to the second round of the Argentina Open. Delbonis squared his FedEx Head2Head series at 1-1 with Frenchman Stephane Robert after a comfortable 6-3, 6-1 result in Buenos Aires, while wild card Mayer – in his first match of the season – prevailed against Portugal’s Gastao Elias 4-6, 6-4, 6-4.

Delbonis, the World No. 48 in the Emirates ATP Rankings, won his first match of 2017 with the straight-sets result against the 36-year-old. He awaits the winner of either his countryman Horacio Zeballos or Portugal’s Joao Sousa.

Former world No. 21 Mayer, whose 2016 season was disrupted by right shoulder problems, needed two hours and 14 minutes to get past Elias. He next meets either fifth-seeded Spaniard Albert Ramos-Vinolas or compatriot Guido Pella.

In final-round qualifying results, Rogerio Dutra Silva, Alessandro Giannessi, Jozef Kovalik and Guido Andreozzi all won through to the main draw.

Damir Dzumhur notched his first ATP World Tour match win of the season on Monday after he felled former Memphis Open finalist Kevin Anderson in the first round. The unseeded Bosnian had fallen three times in his opening match in 2017 but eked out a 6-7(6), 7-6(2), 6-4 victory over the South African.

World No. 86 Dzumhur rallied from a set and 1-3 down in the second set to seal the two-hour, 38-minute result. He booked a second-round meeting with either seventh seed Steve Darcis or Radu Albot.

“It’s really a big win, especially after some tough results the last few weeks,” Dzumhur said. “I lost last week in three sets to [Andreas] Seppi. In Australia, I lost in five sets to Viktor [Troicki].

“So I was playing good but I couldn’t find a way to win the match. After those losses, you lose a lot of confidence.

“This win means a lot really, especially because it was against [Kevin] Anderson, who was a former Top 10 player. It was a great match for me. I was fighting very well. I found that positive energy after losing a set and a break down to win the match.”

Anderson, who reached the final in his last Memphis appearance two years ago (l. to Nishikori), was playing his first match of the season after a hip injury. The 30-year-old South African was ranked as high as No. 10 in the Emirates ATP Rankings in 2015 before an injury-marred 2016 saw his ranking drop to No. 80.

Earlier, American Donald Young also fought back from a set and a 1-3 break down in the second set to upset No. 6 seed Adrian Mannarino 3-6, 7-5, 7-6(4). Young had two match points on serve at 5-4 in the third set before getting the job done in the tie-break on his fourth match point. Japan’s Yoshihito Nishioka had a more routine 6-4, 6-4 win over Spain’s Guillermo Garcia-Lopez.

Former ABN AMRO World Tennis Tournament champion Tomas Berdych started his quest for a second Rotterdam title on Monday with a 7-6(3), 6-4 victory over Marius Copil.

Berdych is making his 10^th appearance at the tournament. The No. 4 seed improved to a 17-7 record in Rotterdam, where he won the title in 2014 (d. Cilic) and reached the final in 2015 (l. Wawrinka).

Berdych had won their previous two meetings in straight sets but qualifier Copil provided a stern test. However, the world No. 130 couldn’t find a way to break, with three chances dismissed by the Czech’s heavy serve. Berdych will take on Viktor Troicki or Open Sud de France finalist Richard Gasquet in the second round.

Dutch wildcard Robin Haase beat Florian Mayer 7-5, 7-6(3). He struck 12 aces and won 82 per cent of first-serve points to edge into a match-up with either Garanti Koza Sofia Open finalist David Goffin or Andrey Kuznetsov.

Doubles specialist Pierre-Hugues Herbert prevailed over Spaniard Feliciano Lopez 7-6(5), 7-6(5). The Frenchman, seeded No. 1 in the doubles, qualified for the singles draw on Sunday by beating Botic Van de Zandschulp.

He reached the final in Acapulco and the 4R at the Australian Open and Wimbledon.

Dreddy Time: One of the most entertaining players on the ATP World Tour, Dustin Brown returns to Memphis. The 32-year-old German, nicknamed “Dreddy” because of his dreadlocked hair, is a human highlight reel on the court.

But he has finished No. 86 in 2015-16.
