German tennis player Alexander Zverev beat fellow rising star Denis Shapovalov at the Laver Cup. The German outclassed the 18-year-old in a tight match 7-6 (7-3) 7-6 (7-5). The 20-year-old recently beat the Canadian at the Montreal Masters this past August.

Earlier on Friday, Zverev's fellow teammates Marin Cilic and Dominic Thiem defeated USA's Frances Tiafoe and John Isner.

Zverev saved crucial set point

Shapovalov saved three break points in the second set to tie it up at 4-4. Zverev again pressed Shapovalov two games later, but the Canadian managed to save four match points. As no breaks of serve were seen, the second set also went to a tie-break. Both players were tied at 5-5 when the German won two points in a row to seal the win.

Zverev won 85 percent of his first serve points and didn't lose his serve once at the Laver Cup. The German failed to convert any of his nine break point tries but didn't pay the price. The match came to an end after an hour and 51 minutes of action.
