Joseph O'Brien claims double with Field King's Field galloped on strongly in the closing stages to open his account in the Mallow Maiden at Cork this afternoon and give trainer Joseph O'Brien a double on the card. The Kodiac colt was sent to post the 11/8 favourite after an unlucky run in defeat when third at Fairyhouse last month. Donnacha O'Brien soon has his mount in front but relinquished the lead to Encantador after three furlongs. He claimed the advantage again shortly after the two furlong pole and galloped on strongly in the closing stages to post a length victory. The winning rider said:- "I had an outside draw today and kept things simple. “He is a lazy horse and has more speed than he shows and is there for you when you want him. When you don't want him, he relaxes nicely. "I never felt like I was going to be beaten and I knew he'd be there for me when I gave him a flick and when I did, he went on for me." Joseph O'Brien had also landed the featured Navigation Stakes with the Wayne Lordan-ridden Ship Of Dreams. (Quotes by Tom Weekes)
