Catalyst continued his dominance of spring 3-year-old racing with another breathtaking performance in Saturday's group two Sacred Falls Hawke's Bay Guineas (1400m).
A spectacular winner of the Listed El Roca-Sir Colin Meads Trophy (1200m) and group three Northland Breeders' Stakes (1200m) in his previous two starts, the super-talented son of Darci Brahma headed to Hastings on Saturday as a $1.30 favourite to complete a black-type treble.
But he was caught wide after an awkward start, and rider Troy Harris had no choice but to burn some petrol and sprint forward to take the lead at the end of the back straight.
After doing that much work early in a race, most horses would be vulnerable in the home straight. But Catalyst is no ordinary 3-year-old. He was able to sprint again, running away from Callsign Mav.
Harris eased Catalyst down in the last 50m, winning by two and three-quarter lengths in a time of 1:22.65.
