Mcdynamo, reserved toward the back of the pack for much of the event, spurted to the front two fences out from home and kicked on gamely to win the Royal Chase for the Sport of Kings (NSA-I) at Keeneland Friday. Under Craig Thornton, the 6-year-old son of Dynamformer was six lengths clear at the wire of the 20-furlong contest. He returned $11.20, $5.40, and $4.80. Shamrock Isle finished second, paying $7.20 and $5.60, followed by Praise the Prince ($3.80) and All Gong. The $2 exacta was worth $67.80. The even-money favorite, Al Skywalker, set the pace right from the start, but tired three fences out and finished well back.Mcdynamo raced on the flat through the autumn of 2001, but six of his eight victories have come since he became a jumper. Michael Moran, who trained Mcdynamo when he ran the flats, owns him. Sanna Hendriks is his current trainer. Mcdynamo was bred in Kentucky by Richard Fox, Nathan Fox, and Richard Kaster. The Keeneland victory pushed Mcdynamo's lifetime earnings to the $350,000 mark. He has won eight races from 17 lifetimes starts, but is an immaculate six-for-eight jumping. He now owns a three-race win streak, having taken the U.S. Supreme (NSA-I) last November.
