In an ominous start to the second set, Bhupathi was broken in the second game. Schwartzman hit a service winner to make it deuce and the Indian only helped the rivals by double faulting, which put them down by a break point.
The Argentines got the break thanks to an unforced error by Bhupathi.
Schwartzman served solid to make it 3-0. Bhupathi and Melzer had a chance to get that break back on Zeballos’ serve but the tall southpaw yet again came up with big serves to save both. In just 19 minutes they had a commanding 4-1 lead.
Bhupathi and Melzer held their serves after that but the lead stayed with the Argentines and they easily pocketed the set and match.
Bhupathi’s forehand went wide to hand the Argentines two match points and they converted first when a double-handed backhand by the Indian kissed the net.
Rohan Bopanna and his Canadian partner Daniel Nestor will open their campaign against Marcos Baghdatis of Cyprus and Marinko Matosevic from Australia.
