Lucas, who had figures of 4-5 from four overs, was playing in the year 7a tourney which started last Sunday and ended on Wednesday.
His hattrick came from Central Hawke's Bay middle-order batsmen in his last over from the No2 delivery with dot balls on either side.
"The first wicket came from a stumping," he said, hailing the glove work of Matthew Flower.
The next came when Josh Bishop snaffled the ball at point from the right-arm off spinner to prompt delirious teammates to remind him he was sitting on a hattrick ball, not that he needed reminding because he had never been in that position before.
He kept his composure, tweaking the ball a tad short and wide as the batsman predictably chased it, only to spoon it to Porirua fielder Lachlan Bailey.
"If I had picked to bowl to a stump he would have blocked it," said Lucas after soaking up high fives and pats on the back although it would have been nicer had Porirua not lost by 15 runs.
It was a special moment for the youngster whose grandfather watches him play for his Porirua CC age-group team on Saturdays when he's not at the crease.
Lucas and his brother, Riley, 9, live in the suburb of Papakowhai where they don't have a grass yard so they tend to play at their grandfather's Whitby home when visiting him.
Lucas said the two of them often had a few disagreements in the backyard but their grandfather dealt with it professionally.
"He's really good because [Riley] normally has a fit and quits the game," he said, emphasising his father and mother Nadine, a kindy teacher, often reminded him that other children didn't often want to play with quitters.
His camp co-coach, Dave Vincent, said Lucas almost claimed a fourth wicket in a row but the ball fell shy of a fielder.
"He's like a pro. He takes it seriously and he's got leadership skills and is one of our leaders," Vincent said of Lucas who has Black Cap aspirations.
The coach said the player's attitude belied his age and made it a pleasure to mentor the Papakowhai School pupil.
It delighted Evan Watkin to see "happy-go-lucky" children have a great time at the camp tourneys, including the time he brought Glenn five times here from the age of 9.
He relished the Bay weather although there were never a shortage of jokes about hosting cricket matches in the province if farmers wanted rain but, generally, the weather gods smiled on the country's No1 summer sport.
It brought back memories for him of an aberration during a "youth test" at McLean Park in 1991-92 when Stephen Fleming was captain and Geoff Howarth coach.
"It was a four-dayer and not a ball was bowled in that game," Evan said, revealing in those days McLean Park didn't have a sand base so while the sun shone the outfield was "absolutely saturated".
In some respects Watkin, who is in his 34th season of umpiring at any level, has done the full cycle from club level to the giddy heights of international matches.
He had an "awesome experience" at the elite level and "it was just fantastic".
"Players like Sachin Tendulkar, Rahul Dravid and Brian Lara stood only 22 yards away from me.
"When I started I had no goals and I never imagined I would get as far as I did."
