Indian Chief added another potential string to Aidan O'Brien's Investec Derby squad when demonstrating an impressive turn of foot to go from last to first in the Bulmers Live At Leopardstown Summer Racedays 2013 Maiden.
The Montjeu colt finished second to Jim Bolger's subsequent Group One scorer Loch Garman on his only start in 2012 and was sent off the 4-7 favourite under Joseph O'Brien.
O'Brien jnr had Indian Chief anchored at the back of the field and was still sat in last turning into the straight in the 10-furlong contest.
However, when the rider gave the signal, Indian Chief moved up a gear and, switched to the middle of the track, swept by his rivals in fine style to easily account for Dubai Deer, putting himself in line for the Dante Stakes at York on 16 May.
O'Brien said: "I was afraid as last year he ran into Jim's horse (Loch Garman) and he emptied out.
"For a Montjeu colt he has plenty of speed. They went a steady gallop and he quickened up well. Being dropped in last in a slowly-run race you might think it's not the right place to be, but he picked up easily.
"He might be a Dante horse and the fellow who won here yesterday (Battle Of Marengo) might come back here (Derrinstown)."
The O'Briens were just denied when Say had to settle for a short-head second behind Kerisa (7-2) in the Irish Stallion Farms EBF Fillies Maiden.
The winner, providing John Oxx with his first success of the season, edged past long-time leader Etesian around a furlong out and although Say layed down a strong challenge, the line came in time for Declan McDonogh's mount.
McDonogh completed a double when swooping late on Stronger Than Me to beat Smoke Charger a length and three-quarters in the www.inba.ie Betting Voucher Handicap.
Leah Claire picked off Tantalising late in the piece to take the Spin 1038 Rated Race for trainer Willie McCreery, while veteran performer Head Waiter, now in the care of Claire Simpson, rolled back the years when taking the Leopardstown Intervarsity Colours Challenge Cup Handicap under Connor King.
The Ross Nugent Foundation Handicap was won in tremendous style by Dermot Weld's Stuccodor (7-2), who looked well ahead of the assessor when recording a clear-cut success in the hands of Pat Smullen.
