The younger Egen was still trying to process the enormity of his innings when the Otago Daily Times contacted him for comment yesterday.
"I don't know if you can really explain it, to be fair,'' he said.
"I was just hitting a pretty good ball and thought I'd run the risk of seeing how well I could go and it sort of came off.''
To help put it into context, according to the respected website Cricinfo there have been eight scores of 300 or more in minor limited-overs cricket matches.
Indian schoolboy Nikhilesh Surendran tops that list for his innings of 334 not out for St John's Church Junior College against Brilliant Grammar School in Hyderabad in 2008-09.
Earlier this month, Brisbane's James Tull staked a claim for the record with an incredible innings of 341 runs off just 130 balls in Queensland's warehouse cricket competition.
Whether Egen's innings is confirmed as a world record or not, he will always have a great
story to tell around the water cooler.
His previous highest score was 138 and "now I've almost tripled it''. He started opening the batting about two years ago and before that he was "the old No nine, 10 or 11''.
Egen leans heavily on the bottom hand and a good portion of his 43 sixes were deposited over "cow corner''.
"The old hockey player swing as they call it.''
The thought of retiring and giving poor old Kaikorai, which could manage just 72 in reply, a break never crossed his mind.
"There was no chance of retiring,'' he laughed.
The Taieri senior team posted a mere 145 runs in the weekend so Egen, who has played senior cricket in the past, might get a promotion next week.
We spared Kaikorai the horror of reporting the bowling figures. The team also avoided further indignity by restricting Taieri to 510 - which was a long way off the world record of 721.
And the bloke who dropped him in the covers early on shall remain nameless. We feel your pain.
