Moiseev has done it all - twice. From Olympics to World and European Championships, he has shown himself to be the man for the big occasion. But what he's never done is to win a World Cup event in his home city because this is the first time Rostov has hosted a World Cup.
The form book suggests he has a very strong chance; the 32-year-old took silver in WC#3 in Hungary and his performance in qualification here was very convincing. "A professional job," he said after finishing in the leading pack.
Hundreds turned out to see that performance and Moiseev is confident many more will flock to the Hippodrome tomorrow. "I think there will easily be twice as many as for the semi-final," he said.
Victory for Moiseev, however, is far from assured. Nine other Russians are among the 36 finalists. Ilia Frolov, who won WC#1, and Serguei Karykin (silver at WC#2) would hope to be in the frame.
The Egyptians Omar and Amro El Gesiry are worth watching tomorrow after strong performances in qualification, along with Alexander Nobis (GER) who led home the second semi-final.
The qualification of both Jamie Cook (GBR) and Remiqiusz Golis (POL) offers the Briton an early chance to revenge the swimming defeat he suffered in Hungary. Expect those two be among the leaders after two events.
