Matteo Rivolta set a new national record in the 100 metres butterfly at the Italian Championships in Riccione on Wednesday.

"I didn't expect to swim so fast in the morning. Although it is not a great time, I guess I am working well and in sight of the Worlds where I apsire to compete in the final" Rivolta said this morning after he set the first record, swimming in 52.06.
