London, July 5 -- Carlos Alcaraz didn't have it all easy on Friday at Wimbledon, but once again, he found a way to win. The Spaniard extended his winning streak to 21 matches after beating Germany's Jan-Lennard Struff in four sets, 6-1, 3-6, 6-3, 6-4, as per the official website of ATP Tour.

"I was suffering in every service game I did today," Alcaraz said, as quoted from the official website of the ATP Tour.

"Love 30, break points down. It was stressful. He kept pushing me. I kind of survived and I am really happy that I got the break and it was done," he added.

Alcaraz is now aiming to become only the fifth man in the Open Era to win Wimbledon three years in a row. He has now won 17 matches in a row at the grass court major.
