Lalita Babar failed to reproduce her fine showing in the qualification round and finished 10th in the women's 3000m Steeplechase final as Indians continued to disappoint in track and field at the Rio Olympics on Monday.
Babar clocked 9:22.74 seconds, nearly three seconds outside her National record of 9:19.76s, set in the qualification round on Saturday.

The 30-year-old Kerala athlete had made the Rio Olympics cut on the last day of the qualification period on July 11 at the hurriedly arranged Indian Grand Prix with a jump of 17.30m.
