Steel Frost made it a hat-trick of successes with a gritty win at Kembla Grange on Sunday.
Trained by Anne-Marie Ruttley, the promising four-year-old wandered around in the straight but managed to grip on in front of fast-finishing pair Arigold and Cannot Be Serios.
“He is a very nice horse,” Spriggs said.
“He is still very green but once he picks it up he is going to make a nice Saturday class horse.”
Steel Frost won his past two starts at Canberra and Goulburn leading into his latest run.
The gelding started as a $4.40 second favourite behind Cannot Be Serios ($2.15) and was given every chance to win the Happy 80th Graham Onley CG&E Benchmark 65 Handicap (1400m) by in-form jockey Blake Spriggs.
Spriggs sat outside the lead before edging to the front a long way from home.
It proved a winning break as Steel Frost saluted in a thrilling photo finish.
