Argentine teen Juan Martin del Potro posted the biggest win of his young career Tuesday, upsetting No. 5 seed and two-time Chennai winner
Carlos Moya 6-3, 6-2 in Mumbai, India.
The lanky 18-year-old del Potro with a strong baseline game is among the new faces that figure to make big waves on the circuit in the future.
"It's a very big moment for me, Carlos was one of my idols," del Potro said. "You have to seize every chance you get against a player like him, and I was determined not to be the one doing all the running."
The Argentine will now meet
Ramon Delgado, who advanced when his opponent, Italian
Davide Sanguinetti, retired after 59 minutes with gastroenteritis, trailing Delgado 6-3, 2-1.
Moya wasn't alone in the seeded exit as No. 7
Juan Monaco fell to
Stefan Koubek 7-6(5), 6-4.
Eighth-seeded
Wesley Moodie needed three sets to edge wildcard
Rohan Bopanna 3-6, 7-6(5), 6-4. The big-serving South African will next take on qualifier
James Auckland.
Germany's Simon Gruel beat Yen-Hsun Lu 7-6(4), 6-3 and will next meet either No. 3 seed
Tomas Berdych or Pole
Lukasz Kubot in the second round.
