Zac Purton believes Fast Network has more to give if called upon as the four-year-old prepares to put his perfect record on the line at Sha Tin on Sunday.

The seven-time champion Hong Kong jockey has been impressed by Fast Network’s two wins from as many starts, with the soft nature of both victories giving him confidence there is more to come from Dennis Yip Chor-hong’s promising galloper.

After cruising to a one-and-a-half-length triumph down the 1,000m straight on debut in June, Fast Network made light work of his 135-pound top weight to effortlessly win by the same margin at the same course and distance last month.

He easily accounted for Cheval Valiant, who boosted the form by winning his following start under apprentice Britney Wong Po-ni.

Purton is optimistic Fast Network will handle his first test at Class Three level in The Federation Of HK Guangdong Community Trophy (1,000m) on Sunday.

“He’s unexposed, he’s lightly raced. He’s a big horse that you would like to think would derive benefit from an outing and he just continues to work well,” Purton said.

“He’s done a good job. He sort of struggles sometimes to get his rhythm out of the gates.

“He copped a little bit of a squeeze there last time but after we’d gone a few strides, he gathered himself, got balanced and from then on travelled really nicely. It was just a matter of waiting for the right time to ask him for his effort.

“He’s been a bit soft on the line in both of his wins, so hopefully when the time comes and he’s got to find a little bit more, he’s got it there.”

Fast Network drops 11 pounds and jumps from barrier 11 in a competitive race. Despite being bred to run further than five furlongs, the son of Wrote is being kept to short-course sprints because of a breathing issue.

“He does have a bit of a breathing problem, which is why he’s started at 1,000m – to allow him to get the oxygen he needs without being on the bit and overdoing it,” Purton said.

“Time will tell, but he certainly does give the feel and he’s bred to do it, but if they can’t breathe, then they’re not going to get there.”

Purton will also pin his hopes on another talented four-year-old, Divano, when he resumes in the Class Three Sai Wan Shan Handicap (1,200m).

The Francis Lui Kin-wai-trained gelding recorded two wins and as many placings from four starts last term.

“There’s a little bit more upside there with him,” Purton said. “He has been a little bit better in the barriers as well. He’d want to sit down and throw himself around, but he is standing better. [He’s] not beginning a lot better, but I think that will come. He just seems to be handling things a bit more comfortably this season.

“Last season he always felt like he was nowhere near the finished product, so hopefully he can just go on with it this year.”

Divano led throughout in his two victories and was placed behind Lucy In The Sky and Bottomuptogether on his other two starts.

The son of Brave Smash has settled off the speed and finished strongly under his own steam in his two recent trials.

“When they’re slow out of the gates, you probably don’t have much of an option, right? You get beaten for speed, but that’s the beauty about the trials,” Purton said.

“You don’t have to be forced into riding them in any manner, you can just allow them to try and deal with different situations. Being in behind them I think is just part of his learning process.”
