Jack Sock continued his winning ways on clay courts Tuesday, beating Spain’s Pablo Andujar 6-4, 7-5 in first round of the Madrid Open.
Sock, the former Blue Valley North star, survived a late challenge from Andujar after taking a 5-2 lead in the second set.
“It got scary there in the second for a little bit,” Sock said. “He’s very crafty. … He scrapped back … I was lucky to get through there in the end.”
It was Sock’s first match since winning the U.S. Men’s Clay Court Championships last month in Houston. He’s now 6-0 on clay this year.

Sock faces No. 12 seed Jo-Wilfried Tsonga of France in the second round Wednesday in Madrid.
Tsonga defeated the Czech Republic’s Lukas Rosol 7-5, 6-3. Also advancing were Gael Monfils and Alberto Ramos-Vinolas.
Maria Sharapova advanced to the third round by beating Mariana Duque-Marino of Colombia 6-1, 6-2.
The third-seeded Russian and defending champion broke Duque-Marino’s serve four times while saving three break points on her own serve.
“She is someone who, if you give her time, creates angles, slices and usually drop-shots a lot more than she did in this match because she has the hands and the ability to do so,” Sharapova said.
Sharapova’s next opponent will be Caroline Garcia of France, who beat the 14th-seeded Karolina Pliskova of the Czech Republic 6-2, 4-6, 6-1.
Fourth-seeded Petra Kvitova of the Czech Republic also advanced, beating Coco Vandeweghe of the United States 6-4, 2-6, 6-3.
Also, Barbora Strycova of the Czech Republic beat Varvara Lepchenko of the United States 6-4, 6-2, and Victoria Azarenka of Belarus defeated Ajla Tomljanovic of Croatia 6-3, 6-3.

In the men’s tournament, fifth-seeded Milos Raonic of Canada served nine aces and broke Argentine player Juan Monaco’s serve twice to win 6-3, 6-4.
Raonic is enjoying a career-high ATP ranking at No. 6 and arrived in Madrid after reaching the quarterfinals or better in nine of his last 12 Masters tournaments.
Also, 10th-seeded Grigor Dimitrov of Bulgaria advanced after Donald Young of the United States had to retire from the match because of injury.
The 25-year-old Young received treatment for back pain while trailing 6-4, 3-0 and was unable to resume play.
Dimitrov will next face Fabio Fognini of Italy.
Nick Kyrgios of Australia reached the second round by beating Daniel Gimeno-Traver of Spain 6-2, 6-3.
