CHENNAI: Sumit Nagal, who recently became the first Indian to beat a seeded player in a Grand Slam tournament, will spearhead the Indian challenge in the men's singles competition of the Chennai Open ATP Challenger 100 tournament beginning Sunday.
The 26-year-old Nagal had entered the second round of the Australian Open last month after beating world no. 27 and number 31 seed Alexander Bublik of Kazakhstan. He is currently ranked 121 in the world.
