INDIANAPOLIS (Indiana), June 25: Tyson Gay ran the second fastest 200 metres of all-time, 19.62 seconds, on a wet track at the US championships on Sunday.

The win came after Xavier Carter, the previous second fastest at 19.63 seconds, crashed out in the semi-finals with a dislocated knee cap problems.
Gay had taken the US 100 metres championship in a season-leading 9.84 seconds on Friday. He will run both in the world championships and said another US sweep might be possible in the 200 metres.
