Martin Guptill says he was only focused on firing New Zealand to victory over Sri Lanka, rather than chasing the record for the fastest ODI half century.
The opener was in sensational form in Christchurch on Monday, as he bludgeoned an unbeaten 93 from just 30 deliveries to guide the Black Caps to a 10-wicket win.
Having survived an early scare when he was dropped by Milinda Siriwardana on his first delivery, Guptill hit nine fours and eight sixes to race to 46 not out after just 12 balls - on course to break AB de Villiers' half-century world record of reaching the milestone in 16 deliveries.
The 29-year-old eventually fell just short, hitting the landmark off 17 balls, but that was still enough to make him his country's fastest man to 50 runs, beating the 18-ball total of Brendon McCullum.
New Zealand ultimately reached their target of 118 in just the ninth over to wrap up a comprehensive win.
"The plan was always to go out and be aggressive, and create a strike rate at the top of the innings," said Guptill.
"[Was I thinking about the record?] No not at all. I was just swinging. I was trying to hit as many runs as I could, as quick as I could.
"The first time I thought about the record was when the umpire said to me: 'You've got two balls to get it or something like that.' That's the first time it came to my head.
"Sometimes I am statistics-minded. But it's more Ross Taylor telling me that I've got 100 runs to beat this person. I just go out there and try to do it. Ross is a bit stats driven."
The victory gives New Zealand a 2-0 lead in the five-match series, but Guptill knows they must maintain their focus to ensure Sri Lanka are not able to fight back.
He added: "We've put in two complete performances so far, our bowlers are right on top of the Sri Lankan batsmen, but we know they've got some quality players in this side.
"[Tillakaratne] Dilshan got a couple a hundreds in the one-day series last year and he's had a fantastic year in one-day cricket so we still have to bowl well."
