The 23-year-old electrician achieved the sprint double, equalling the efforts of Hobart runner Sam Crosswell in 2006.

He also made it back-to-back Devonport 200m titles and is thought to be the first man to achieve that feat since 1993.

Pfundt ran from a mark of 17m and held on to beat Hobart's state 100m and 200m champion Jarrod Gilroy who finished second with Hobart's Charlie Leek third in a time of 20.74.

"It's pretty good to win the double and I think I feel better than last night," Pfundt said.

"I was originally marked off 19m and I thought I'd be a fair chance from there but was pulled back two metres and doubted myself a bit - but I'm glad I could get up."

He said he would put celebrations on hold until after Burnie and planned to put his winnings toward paying off his house.

"I've been more focused this season and have just had a more consistent season," he said.

Another Fay Denholm stable runner joined him as Devonport 200m champion with Westbury 17-year-old student Abbey Walters continuing her stellar season by winning the women's final.

Walters backed up from her Latrobe Gift win on Boxing Day to gain her seventh win of the season beating home another Denholm-trained runner, Laura Nicholson, and Ulverstone's Abbey Chapman in 23.84.

"I feel pretty good - I thought they were catching me and then they weren't there any more," the Launceston College student said.

"I saw Laura and thought I'd better dig that bit more.

"I thought `Oh my God I'm dying but I have to keep going."'

Walters paid tribute to her coach Fay Denholm for her outstanding season but said she never expected to achieve two big carnival wins this season. "She has helped me a lot and been very supportive and has got me to train a lot more," she said.
