Guillermo Garcia-Lopez hung on and Paul-Henri Mathieu played the role of Portuguese spoiler on Tuesday at the Millennium Estoril Open.

Garcia-Lopez was leading by a set and 5-1 in the second against German Michael Berrer. But Berrer crawled back into the match and forced a second-set tie-break, where Garcia-Lopez ultimately prevailed to win the match 6-3, 7-6(3).

“He was playing better and better every point. He felt more free on court, and I was feeling the pressure to close the match,” Garcia-Lopez said.

The No. 5 seed moves into the second round to face French qualifier Stephane Robert for the first time.

Mathieu had the President of Portugal attending his match against Portuguese Gastao Elias, who cracked the Top 100 in the Emirates ATP Rankings for the first time this week. Elias’ ranking jumped 23 spots after he won the Torino Challenger in Italy on Sunday. But it was Mathieu who advanced on Tuesday, winning 6-3, 6-4 in one hour and 31 minutes.

“It’s never easy to play a player who is from the country of the tournament. He was playing with great confidence,” Mathieu said. “So I’m happy with the victory in two sets.”

The Frenchman will meet his countryman and No. 1 seed Gilles Simon in the second round. Mathieu leads their FedEx ATP Head2Head rivalry 3-1.

#NextGen star Kyle Edmund of Great Britain also advanced on Tuesday, beating Spaniard Daniel Gimeno-Traver 6-3, 7-5. Edmund will face No. 3 seed Benoit Paire of France for the first time. Spaniard Inigo Cervantes also moved into the second round. He beat compatriot Daniel Munoz de la Nava, 6-4, 6-1. Cervantes will play No. 2 seed Nick Kyrgios.

WEDNESDAY PREVIEW

Kyrgios celebrates his 21st birthday Wednesday at the Millennium Estoril Open, site of the first ATP World Tour final of his career. Kyrgios, runner-up to Richard Gasquet in 2015, plays his first clay-court match of the year against Cervantes. The Aussie hasn’t competed since April 1, when he fell to Kei Nishikori in the ATP Masters 1000 Miami semi-finals.

All was not lost for Kyrgios in Miami. After beating Milos Raonic in the quarter-finals, Kyrgios rose to a career-high No. 20 in the Emirates ATP Rankings, solidifying his place as the No. 1 player in the ATP World Tour Next Generation. Kyrgios also became the first Next Generation star to win a singles title when he swept Gasquet, Tomas Berdych and Marin Cilic in February at the Open 13 in Marseille.

Joining Kyrgios in Estadio Millennium are fellow Next Generation players Edmund and Borna Coric. The sixth-seeded Coric takes on Rogerio Dutra Silva. Play begins with a pair of Spaniards in the final first-round match of the draw: No. 8 seed Pablo Carreño Busta versus wild card Fernando Verdasco. In a rain-delayed final at Bucharest on Monday, Verdasco defeated Lucas Pouille for his seventh singles title.

Joao Sousa, the top player from Portugal at World No. 34, had the honour of meeting his country’s president on Tuesday at the Millennium Estoril Open.

President Marcelo Rebelo de Sousa played an influential role in bringing the ATP World Tour to Portugal in 1990. He was gifted with a tennis racquet from Sousa before making his way to Estado Millennium to watch Portugal’s Gastao Elias, who cracked the Top 100 in the Emirates ATP Rankings on Monday, face Paul-Henri Mathieu (the Frenchman won 6-3, 6-4).

“I think it’s great for the tournament,” Mathieu said after his win. “It’s great for tennis. It’s an honour to play in front of him.”

Sousa, the fourth seed this week, will open his campaign against Nicolas Almagro in the second round.

Tournament officials at the BMW Open by FWU AG in Munich can’t seem to catch a break from Mother Nature this week. Snow disrupted qualifying matches on Sunday at the outdoor clay-court tournament. On Tuesday, rain was to blame for play being suspended and only three matches reaching completion.

In a battle of German qualifiers, Florian Mayer bested Matthias Bachinger 6-4, 6-4. Mayer, former World No. 18, returned to the ATP World Tour last week at the BRD Nastase Tiriac Trophy in Bucharest after more than seven months off because of a torn right adductor tendon. The 32 year old will face another compatriot in the second round, No. 4 seed Philipp Kohlschreiber, who received a first-round bye.

Mikhail Kukushkin of Kazakhstan also moved into the second round after Russian Evgeny Donskoy retired because of a hip injury down 6-2, 3-0. Kukushkin, No. 88 in the Emirates ATP Rankings, will face No. 5 seed Fabio Fognini of Italy or German wild card Maximilian Marterer.

The Fognini-Marterer match will be first up on Center Court on Wednesday, followed by the completion of the contest between #NextGen star Alexander Zverev and Malek Jaziri of Tunisia. Their match was suspended on Tuesday with Jaziri to serve up 5-4. The World No. 64 beat the German in straight sets last week to reach the quarter-finals of the Barcelona Open BancSabadell.

Three other singles seeds are scheduled to play on Wednesday, including No. 7 Vasek Pospisil, No. 3 Dominic Thiem and No. 6 Thomaz Bellucci. Juan Martin del Potro also is scheduled to continue his comeback against German Dustin Brown.

WEDNESDAY PREVIEW

Following a rainy and snowy start to the BMW Open by FWU AG, the stars come out Wednesday in Munich. Del Potro plays in his first clay-court match since May 16, 2013. Munich marks del Potro’s fourth tournament of 2016, but his first on clay since 2013 ATP Masters 1000 Rome. The former World No. 4 has had three surgeries on his left wrist since then, and his opponent Brown is returning from a wrist injury as well. The dreadlocked German has not played since a Challenger in Jonkoping, Sweden seven weeks ago.

The final two matches scheduled on Center Court are second-rounders. No. 3 seed Dominic Thiem, who is 26-7 with two titles in 2016, meets Santiago Giraldo for a spot in the quarter-finals. Only World No. 1 Novak Djokovic has more wins this season with 28. Also in second-round action, Ivan Dodig faces No. 6 seed Thomaz Bellucci, who ended a seven-match losing streak Monday.

Gilles Simon and Nick Kyrgios visited the Autódromo do Estoril on Monday to test out some sport-tuned Peugeot cars with professional Portuguese drivers.

Simon and Kyrgios, who are the top two seeds at this week’s Millennium Estoril Open, took the passenger seat for some very high-speed laps.

“It was very nice and the first time on a track like this,” said Simon. “It was really impressive how fast the professional drivers could go, especially on the bends and their breaking. At times you think you’re doing a U-turn. It’s a lot of stress if you’re not used to it, but I had a lot of confidence in the driver.”

“It was really fun,” said Kyrgios. “To get in a car with professional drivers was scary at first, but when you get used to it you put your trust in them. They did an unbelievable job. It shook me up on the first corner, when he really hit the brakes and started drifting.”

Simon then took out one of the cars for a couple of laps under the tutelage of one of the pro drivers. Kyrgios, having only recently passed his test to drive a manual car, decided not to give it a go. “I like driving, but when I’m back home I drive a lot,” said Kyrgios.

Simon added, “My turn was slower! I did two laps, the first lap was good and saw how I could do with it. But in the second lap, I lost control on the grass. It’s a really nice place though, driving at a former Formula One track.”

Former Formula One champions Alain Prost (1984, 1987-88), Ayrton Senna (1985), Nigel Mansell (1990, 1992) and Michael Schumacher (1993) previously won Grand Prix races on the track. Senna won his first Grand Prix in Estoril.

Sixth seed Jiri Vesely recorded his sixth match win on clay this year by beating Thiemo de Bakker 6-3, 7-5 in one hour and 33 minutes on Tuesday for a place in the TEB BNP Paribas Istanbul Open second round. Vesely reached the Marrakech semi-finals (l. to Coric) earlier this month.

Fifth seed Marcel Granollers and seventh seed Teymuraz Gabashvili are also in action today.
