Jett to follow Jezki path Jessica Harrington is targeting the same race in which she introduced champion hurdler Jezki for his unraced half-brother Jett. A four-year-old bumper at Leopardstown's fixture at the end of January is already on the cards. Also related to the likes of Grade One winners Jetson and Jered, the youngster has the pedigree to be above average. "Jett is a half-brother to Jezki and Jetson by Flemensfirth," said Harrington. "He's a very straightforward horse and he'll probably run in the first four-year-old bumper at Leopardstown which Jezki went for." Harrington also feels the Michael Buckley-owned Rock The World has a future despite finishing third in a Grade Two over hurdles last time out and believes he will not be seen at his best until he tackles fences. "Rock The World is a chaser in the making. He'll run at Navan on Saturday in a two-mile rated race and he could go for the novice handicap hurdle at Leopardstown over Christmas. He has the cut of a chaser and jumps hurdles like a chaser," said Harrington.
