Champion jockey Zac Purton believes promising galloper Superich is capable of bigger and better things, including a possible tilt at the four-year-old series.

The Frankie Lor Fu-chuen-trained gelding has won three times in his five-race career to date, but Purton believes it could be just the beginning as he steps up in distance for the first time on Sunday in the Class Two Eleanor Handicap (1,400m) at Sha Tin.

The rise in distance will also be met with a step up in grade as the son of Red Giant experiences Class Two company for the first time.

Despite winning over 1,000m and 1,200m, Purton said Superich had always given him the feel of a horse searching for more distance.

“He hadn’t showed much speed in his barrier trials, so I said to Frankie that he felt more like a 1,400m-1,600m horse,” Purton said.

Superich was able to win in unlikely circumstances first-up last month, where as favourite he found himself in a number of situations which would have seen lesser horses throw in the towel.

“He wasn’t entitled to win,” Purton said of the first-up run. “He wasn’t able to show much speed into the first corner and he got himself into a bit of an awkward spot.

“I then had Karis Teetan just inside me on a horse that didn’t take the corner, spearing off the track, so he speared me off probably five or six horses.

“Then I had to come back and was wide, he was continually taken off his line around the circle, he was in a position where he just shouldn’t have been able to win.”

Superich has trialled since his first-up win, comfortably moving past a number of talented horses.

“He looks good, his trial was good and I think it’s the time to go up to 1,400m – you could see last time it took him a little while to catch up,” Lor said. “This Class Two is only a [rating] 90-70, which should suit him.”

Despite drawing barrier two where he is expected to get a nice run into the race, Superich won’t get things all his own way with impressive last start winner Green Energy in the field alongside Coby Boy.

The Danny Shum Chap-shing-trained Green Energy was able to produce strong closing sectionals in his stunning last-to-first victory last month, before being scratched two weeks later at the barriers after being caught in an incident.
