Three Chimneys Farm's Great White (Volatile) tuned up for his dirt racing debut in Saturday's GI Toyota Blue Grass by working a half-mile in company in :47.60 over a fast track a Keeneland Sunday morning.Working with the 3-year-old maiden Just Munny (Justify), Great White, accompanied by rider Omar Torres, started two lengths behind his stablemate and finished two lengths in front with fractions of :35.60, :47.60 and galloping out five furlongs in 1:01.20.“He started off slow but then flew down the lane and Alex [Achard] had a hard time pulling him up,” trainer Jon Ennis said. “It was a sharper work compared to last week [a half-mile in :52.60] when we wanted him to get a feel for the track.”Great White is based at the nearby The Thoroughbred Center, where he returned after the work. Ennis said Great White would come back to Keeneland Wednesday or Thursday and would have a morning Paddock schooling session prior to the Toyota Blue Grass.Great White has won two of three starts over the all-weather surface at Turfway Park, taking the Feb. 21 John Battaglia Memorial in his most recent race.“They are different horses and this one is probably a better horse. He has a high cruising speed,” Ennis said. “Epic Ride has some distance limitations but a mile and an eighth or a mile and a quarter is not an issue with (Great White). It would be interesting to go to the [Kentucky] Derby with him.”The post Great White Works at Keeneland Ahead of Blue Grass Tilt appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
