Juan Martin Del Potro looks on

Juan Martin del Potro made a winning start at the Los Cabos Open, but he was made to work for it by world number 446 Marcos Giron.

The Argentinian lost a 4-2 lead in the opening set against qualifier Marcos Giron – who was playing in his first ATP Tour event in four years – but powered through to win 7-5 6-4.

“It was a tough match for sure,” said Del Potro.

“I didn’t expect to play this difficult of match against a 400 player but he did really good.

“We played a great first set but then in the end, I took my chances to close the match in two sets, and I’m glad for that.

“My dream is to win again in Mexico. In Acapulco I did well and had a great time, that is why I have a great memory and that is why I decided to play here.

“The affection that the Mexican people show me- hopefully I can continue to advance to share more days with them.”

Del Potro will now face Egor Gerasimov in the quarter-final after he eliminated defending champion Sam Querrey.
