Coach Stephen Shale was proud of his batsman for providing the platform considering he had scored four half centuries here last year and 47 more runs to boot.
"He's due for some runs tomorrow so we'll put a little bit of pressure back on him," a jovial Shale said.
O'Meegan's father, Oliver, was at work on Wednesday but, on hearing about his son's prowess, the orthopaedic surgeon drove down from Hamilton that night.
In the two games yesterday, O'Meegan scored a brisk 22 from 19 balls in the 30-over affair against Dannevirke at Park Island, Napier, in the morning but managed 13 although Southwell could only score a total of 59 runs in their loss to Wairarapa in the afternoon.
No2 opener Gus Borren, of Wairarapa, was the second century maker in his side's 61-run victory over Johnsonville at Frimley Park No2.
The 13-year-old righthander, whose step-brother is Dutch international skipper Peter Borren, of Christchurch, scored seven fours in his educated 109.
"I tried to knock the ball around because it was a grass pitch so it was hard to score boundaries," said the teenager who will attend Rathkeale College this year from Masterton Intermediate.
So did the elder Borren influence his game?
"He gave me a few tips when I was young but he's pretty busy nowadays."
Wairarapa yesterday lost to Cambridge in the morning in the 30-over match but beat Southwell in the arvo.
No doubt Borren, akin to O'Meegan, wants to take his game to the first-class or the Black Caps level should opportunity knock on his door.
Noah Gray, of Piako Knights (Matamata), doesn't want to miss that ride either after the No4 batsman took 102 balls to score exactly 100 runs, including eight fours and two lusty sixes in the 22-run victory over Upper Hutt.
It's the second ton for the 13-year-old right-hander who is heading off to Morrinsville College this year. His first was for Waikato Valley CC, a university age-group club side.
Gray was so relieved to score his century on Wednesday that he threw his bat at the next delivery and went out.
"It was such a relief because I got told I was in the 90s and it lifted a huge burden off my shoulders," he said, delighted to be playing on grass wickets yesterday as opposed to artificial ones at home.
Coach Bruce Wilton said he was following Gray as a year 5 pupil and he was a hard hitter of the ball.
"He's developed a lot in the past 12 weeks and he practises a lot, too."
Bevan Cox, 12, of Eastern Suburbs (Wellington), was the toast of the bowlers when he took 5-17 from six overs in their 13-run win over Dannevirke.
At his fourth camp, Cox's haul included a hat-trick in his third over from the fourth ball as he sent batsmen No2, 4, 5, 6 and 7 back to the sideline.
"It's my best figures," said the Evans Bay Intermediate pupil bound for Rongotai College.
All the wickets were clean-bowled ones for the right-arm medium/fast bowler who comes in at first change in a team that his father, Robert Cox, coaches and manages.
Cox has been playing since taking up Milo cricket as a 4-year-old.
