Medhurst's outsider Chilled Out won Monday night's $5000 Tasmanian Oaks at Mowbray by almost eight lengths.

After jumping midfield from box 3, Chilled Out got a freakish rails run approaching the first turn and, in the blink of an eye, she was five in front and the race was over.

It was Medhurst's fourth win in the classic following on from Kialdu Kate in 1994, Emily's Idol in 1996 and Demi Cali in 2015.

Inducted into the Hall Of Fame in 2017, Medhurst has won more feature races than any other trainer in Tasmanian greyhound racing history.

Order was restored for punters in the Tasmanian Derby when Gary Johnson-trained favourite Buckle Up Azona won by almost four lengths.

After jumping in front from box 1, Buckle Up Azona was burnt off by Vintage Dancer but he regained the lead coming off the back and proved far too strong.

Although Johnson has won the Oaks three times, it was his first Derby success. He also supplied runner-up Buckle Up Carter

Dilston owner-trainer Pat Ryan may have found the next star of Tasmanian greyhound racing.

Currajong Kid's impressive debut win at Devonport drew comparisons with established stars Peco Can and Stop Line.

Racecaller Shane Yates described it as "the most exciting racetrack debut since Peco Can set tongues wagging in April 2018."

Currajong Kid went 25.25 for the 452m which greyhound historian Greg Fahey said was the fastest time ever recorded at Devonport by a juvenile having its first start.

Assistant trainer Brennan Ryan said it was a huge thrill for the family, as Currajong Kid was the first pup they had reared.

"He was actually whelped in Queensland because we weren't set up here at the time," Ryan explained.

"He stayed there until he was three months old then they sent him to us and we reared him.

"It's certainly been a long 18 months to get him to the track but we like to take our time.

"We're not getting carried away but we think he's the best dog we've had in Tasmania without a doubt."

Plans are to give Currajong Kid his next start in a grade 6 race in Hobart on June 20.

Meanwhile, Peco Can went on her winning way at Devonport on Tuesday, easily winning the Invitation as $1.22 favourite.

It was her sixth win in a row and 22^nd from 28 starts.
