Sergei Prokofiev ran out an impressive winner of the opener at Navan this evening, the Irish Stallion Farms EBF Race.

Second on debut at Dundalk, the son of Scat Daddy was expected to go one place better today, going off the clear 2/5 favourite under Ryan Moore.

Prominent throughout, the Aidan O'Brien trained colt was sent to the front over a furlong out, and he soon shot clear, going on to score easily by seven and a half lengths.

Naas winner Pride Of Pimlico finished second at 4/1 under Kevin Manning for Brendan Duke, while Sunday Spark was a head back in third.

"We're delighted with him. Donnacha loved him when he rode him in Dundalk," said O'Brien.

"He's a big powerful horse and has plenty of speed. He came on as obviously he was never away before Dundalk.

"We'll look at the Marble Hill or the Rochestown with him. Ryan said he didn't think six would be a problem, five or six. He went to the line strong.

"That was nice for his second race as we don't have the novice races and you are limited after you win a maiden.

"We always thought he was very nice and between now and Ascot we'd like to get another one into him."
