London, Aug 3 :  India's athletics campaign at the London Games got off to a disappointing start with shot putter Om Prakash Singh faltering in the qualification round and finishing 10th in group B here Friday.

Om Prakash failed to make the finals and was ousted after he fouled in his third attempt to finish with a best of 19.86m, which is below his national record of 20.69m he managed in the run-up to the Games in May.

The 25-year-old, who is participating in the Olympics for the first time, finished 19th overall.

In his first attempt, Om Prakash touched 19.40m well behind American Reese Hoffa who led the qualifiers with an impressive 21.36m throw, while German David Storl took the second spot with 21.15m.
