Eaglefield driven out to score© Photo Healy Racing
Eaglefield held on from the closers at the end of the seven furlong maiden for three-year-olds and older in Leopardstown.
Jim Bolger 's Gleneagles gelding tracked front-runner, and main market rival Jeroboam and he was the only horse able to chase the pace approaching the straight.
The front pair raced clear in the final quarter of a mile and Eaglefield was ridden to get the better of Jeroboam at the furlong pole.
The pace told in the closing stages as he was all out to hold on by a neck and a head from the finishers Baldomero (8/1) and Emilie Gray (7/2) respectively. Jeroboam dropped out of the placings to fourth.
Una Manning, representing Bolger, said: “I’m delighted for Mr Yue who is a great supporter of ours. He’s from Hong Kong and has been with us a few years.
“I’m told we’ll see how the handicapper treats him and go from there.
“Kevin (Manning) said they went a right gallop the whole way and he battled well. You’d be happy with him.”
Manning added: "We have gone a very good gallop and I couldn't let Ryan (Moore on Jeroboam) go, he was my main danger and I couldn't give him any rope around there.
"Conditions are tough up the straight and I paid for it in the last 10 strides. He just ran a little on empty the last 10 strides but he was entitled to considering the way the race was run.
"Inexperience probably beat him in Gowran. Jim made a very good call to back him up four days later and get the job done."
Eaglefield had finished runner-up on debut at Gowran Park on Wednesday.
