But the 16-year-old proved to be the star of the show, taking six wickets for just one run in Riverside's semi-final contest against Kings Meadows Blue.

The miraculous feat included a double hat-trick - four wickets from four balls - as the grade 10 student sent down his right-arm off-spinners.

"First ball, I was quite nervous but it hit the stumps and was pretty excited with myself," he said.

"I wasn't really expecting to get four in a row but then got the three in one over and then the first ball of my next was the fourth - the double hat-trick."

Teammate Ben Kidd also whacked 55 off just 15 balls in the semi-final, backing up his 59 from the same amount in November 5's round two and outdoing Jack Manix-Geeves 41 off 15.

Riverside High teacher Toby Musovic managed to capture the hat-trick moment on film - comparing the rare occasion to a hole-in-one.

"I've played for 15 years and had a few bowls in that time but never got close to a hat-trick," he said.

"When he was coming in for his hat-trick ball, I was standing at square leg and I thought I might film it just in case it did happen and we now know that it did."

Stevenson's side were victorious on the day, winning the grand final against St Pats by six wickets.

Cricket Tasmania club development officer James Jennings said the championships were "a great opportunity" for players.

"We were really pleased with the spirit the games were played in and this allowed for a great environment for all players involved and we are excited to see these players now representing their local club this summer," he said.
