Indian tennis star Sumit Nagal continued his fine form as he entered the quarterfinal of the ongoing Perugia Challenger.
On Wednesday, the sixth-seeded Indian toppled unseeded local Alessandro Giannessi in a three-set thriller 0-6, 7-5, 7-6(7-5).
In the opening set, Nagal received heavy thrashing after the Italian blanked him 6-0.
However, the 77th-ranked Indian did not back down from a fightback and kept things close in the following set before earning a lone break and winning the set 7-5 to take things to the decider.
As for the final set, it was 'game on' for both the competitors, who eventually took to the tie-breaker, where Nagal survived to take the set 7-6(7-5).
In the quarterfinal, the Indian will face off against the winner of the pre-quarterfinal clash between Maks Kasnikowski of Poland and third seed Borna Coric of Croatia.
Following the conquest at Heilbronn, the Indian has assured himself of a spot in the singles event of the Paris Olympics next month.
