River flows to smooth success
The betting suggested that Galway's Ladbrokes Mobile Maiden Hurdle was a match and so it proved, with Tigris River inflicting a second defeat of the week on Zafayan.
Dermot Weld's Chester Cup third Zafayan, who chased home the exciting Bachasson on the opening day of the meeting, went to the front two out, but even-money favourite Tigris River was in his slipstream.
They jumped the last in unison but the market leader had more in the tank and surged clear under Barry Geraghty to triumph by nine lengths.
Winning trainer Aidan O'Brien was represented by his son Joseph, who said: "It looked a match on paper and possibly Mr Weld's horse was coming back quick enough.
"It's nice to get a win with him and we'll see where we go now. His jumping needs to improve but hopefully he'll come on a bit and the experience will help.
"He jumped well the last time and possibly not quite as well today but it's only his second run over hurdles.
"He's versatile ground-wise as long as it isn't bottomless. He's a grand horse, has a good attitude and I'd say there are plenty of good days in him."
Weld did manage to register his fourth success of the week when First Figaro justified 10-11 favouritism in the Ladbrokes "Your Sport Your Way" INH Flat Race.
