Focus On Venice resisted the late thrust of Michaelmas to claim the Irish Stallion Farms EBF Maiden at Leopardstown.
The Aidan O'Brien-trained Michaelmas was sent off an easy-to-back 11-10 favourite for a seven-runner race made up of unraced juveniles and looked likely to collect when travelling strongly at the top of the home straight.
However, Focus On Venice knuckled down to his task admirably under Kevin Manning and with Michaelmas running green once coming under pressure, Jim Bolger's youngster passed the post a head to the good.
Bolger said: "Kevin said it was very hard to keep straight with the wind - they are difficult conditions today, but he does seem to handle soft ground.
"We'll be stepping him up to seven furlongs and he's a horse I can see going on to better things."
