An impressive Shelton holds off his compatriot Wolf in Melbourne

Ben Shelton got into the last eight of the Australian Open after defeating J.J. Wolf in the American duel.

In a very close first set, with both players winning their service games, Wolf took the lead in the tie-break after his opponent's error on a climb to the net and took the set 7-6.

The match changed within the second set, Shelton led 3-2 when he got the first break of the match, which he managed to finish at 6-3 to level the duel. The next set also saw both players play excellent service games, and they reached a tiebreaker that again went to Wolf.

In the fourth set the balance was maintained on serve, but this time the 20-year-old was better on the deciding points, taking the tie-break and forcing victory in a set. The last set ended the physical superiority of Ben Shelton, who was intact while Wolf gradually fell and moved less.

The match was marked by the aces that each player achieved, with 23 for Shelton and 19 for Wolf. The final score was 6-7, 6-2, 6-7, 7-6, 6-2 for the young star Ben Shelton. His next rival will be the winner of the match between Tommy Paul and Roberto Bautista Agut
