He would know.

The 27-year-old has bowled 11 perfect games, his most recent coming on Monday night in the Warrnambool Tenpin Bowling Association Guys and Dolls league.

It was his ninth time reaching 300 at his home base, while the remaining two were at Mentone and Morwell in the country cup.

His return to the top on Monday night was a few weeks in the making, with scores of 279 and 256 in the rounds prior.

“I was around about there the last couple of weeks,” Altmann said.

“I thought I was a good chance of getting another one.”

The composed bowler was typically calm throughout Monday night’s game, saying he did not feel the pressure as strike after strike built up.

Altmann said he simply “rocked up” and practiced as normal, with things falling into place from the first frame.

“I just had heaps of strikes in a row and felt pretty comfortable,” he said.

“I didn’t know it was going to be a 300 (game), though.

“I was pretty calm throughout. Probably going into the 10th (frame), after getting the first one in the 10th, I thought, ‘I might be a bit of a chance here’.

“It was really good.”

The talented bowler has been honing his craft for about 10 years now, first getting involved in the sport when some of his Brauer College schoolmates encouraged him to go along with them.

Since then, he has gone from strength to strength.

Altmann said he bowled his first 300 game a couple of years ago in Warrnambool, and has been steadily building up a collection of perfect games since, and is now nearing a dozen of the feat.

He has also represented Northern Territory in the state team.

Altmann said he originally tried out for the Victorian team but, after missing the cut, was “drafted” to Northern Territory’s ranks for the competition, which was held in Werribee.

“We ended up coming seventh or eighth, around that mark,” he said.

“It was pretty good. I was still sort of new to it then and it was a good experience.”

Warrnambool Tenpin Bowling Association adult co-ordinator Sandie Rogitsch said it was great to see a third 300 in the association this season, which wraps up this week.

Jason Drake also bowled a 300, while Jackson McGifford broke through for his first perfect game.

“There’s been some pretty good individual performances,” she said.

“Especially David and Jason and Jackson.

“They’re putting the work in … and reaping the benefits of their hard work.”
