Sania Mirza's US Open singles campaign wilted in the second round with 10th seeded Italian Flavia Pennetta routing the Indian 6-0, 6-0 in a grossly lop-sided match in New York on Wednesday.
The Indian could watch only helplessly as Pennetta blew her away, completing the 50-minute whitewash without any fuss.
Sania made as many as 28 unforced errors in the 12-game match, compared to just six winners, spread equally on both sets.
In the first set, Sania was broken thrice while the Indian squandered the only break point that came her way.
She made 16 unforced error in the 22-minute set, four times more than Pennetta.
In the second set, Sania made 12 unforced errors, twice that of Pennetta. Only twice she had a chance to break the duck but Sania wasted the game points she had on the first and fifth games.
Overall, Pennetta hit 20 winners, 13 in the second set alone.
Pennetta was in red hot form against her Indian opponent who has been mostly playing ITF events prior to the Grand Slam.
