ETOBICOKE, Ontario - Favored Uncaptured ($4.60) came from off sizzling fractions to land his stakes debut Saturday at Woodbine in the $150,000 Clarendon Stakes. With the wind at his back, Saratoga shipper Jocosity set splits of 21.35 and 44.23 in the 5 1/2-furlong dash for Ontario-bred 2-year-olds. Uncaptured rallied three wide from third on the turn and caught Jocosity at the eighth pole before pulling away to prevail by 5 1/2 lengths in 1:03.05.  Jocosity finished a clear second, and the slow-starting first-timer River Seven closed for third in a field reduced to seven with the scratch of Calgary Cat. Patrick Husbands rode Uncaptured for trainer Mark Casse, who won last year’s Clarendon with Making Amends. “He’s a beautiful-moving horse,” said Casse. “If you look at him, he’s not hard yet. I think he has some improvement coming. Maybe, this will finally be my Queen’s Plate horse.” Uncaptured, now unbeaten in two starts, banked $90,000 for owner John Oxley.
