Martin Guptill became the first man to score a double hundred in a Cricket World Cup knockout match and propelled co-hosts New Zealand into the semi-finals as they claimed a 143-run win against West Indies.
The 28-year-old batsman was dropped in the first over before going on to score 237 from 163 balls - including 24 fours and 11 sixes, one of which found the roof of Wellington's Westpac Stadium in the final over.
The record-breaking innings, which was the second highest one day international score of all time behind Indian Rohit Sharma's 264, helped New Zealand to 393 for six.
In reply, West Indies were all out for 250 in 30.3 overs, with Trent Boult claiming four for 44 to become the leading wicket taker in the tournament.
Cricket World Cup 2015: 10 young players to watch
Cricket World Cup 2015: 10 young players to watch
1/10 Usman Ghani, 18, Afghanistan
At just over 18 years old, Ghani is the youngest player at the tournament, but the attacking opener already has an ODI century to his name. If the Aghans are to spring a shock, much will depend on him getting them off to a good start.
2/10 Pat Cummins, 21, Australia
With his wonderful action and searing pace, Cummins burst onto the scene when he took seven wickets as an 18-year-old Test debutant against South Africa. Terrible injuries have prevented him from adding to his solitary Test cap, but now the stage is set for Cummins to re-establish himself as one of cricket's hottest talents.
3/10 Mominul Haque, 23, Bangladesh
A compact left-handed batsman, Haque will occupy the No.3 spot in the Bangladeshi batting order. He has already made 24 ODI appearances, but thus far has enjoyed more success in the longer format - in 12 Test appearances he has plundered almost 1200 runs at 63.05, with four centuries.
4/10 Jos Buttler, 24, England
One of the genuine box-office talents in the England squad, Buttler's 121 against Sri Lanka last summer was the most eye-catching innings of the season. His keeping needs work, but as a mid- to lower-order batsman he has the talent to change the course of a game in the blink of the eye.
5/10 Akshar Patel, 21, India
One of the few positives of India's disastrous recent Tri-Series with Australia and England was the consistency of Patel, who was miserly and probing with his tight left-arm spin. He enjoyed a superb 2014 IPL season with 16 wickets and an economy rate of just 6.22 for Kings XI Punjab.
6/10 George Dockrell, 22, Ireland
Despite having been a mainstay of the Ireland side since his debut in 2010, and with four county seasons at Somerset under his belt, Dockrell is still only 22. The canny spinner was named the ICC Associate Player of the Year in 2012, and he has been touted to follow Eoin Morgan into England colours.
7/10 Kane Williamson, 24, New Zealand
Williamson is the most consistent performer in a dangerous New Zealand batting line-up, his devastating recent form in all forms of cricket cementing his reputation as one of the most exciting, talented batsmen in world cricket. Having recently had his action cleared, he can now resume bowling his useful off-spin.
8/10 Ahmed Shehzad, 23, Pakistan
Despite his tender age, Shehzad boasts a wealth of experience, with over 50 ODI appearances and six centuries to his name. More of a classical, patient opener than a David Warner-esque pinch-hitter, he will lay the foundation from which Pakistan's big-hitting middle order can tee off.
9/10 Quinton de Kock, 22, South Africa
Since making his debut just after his 20th birthday, De Kock has been an aggressive, punchy performer at the top of the South African order, plundering six hundreds in just 36 matches. A tidy gloveman, who by taking over keeping duties has allowed AB De Villiers to focus on his batting, to devastating effect.
10/10 Tendai Chatara, 23, Zimbabwe
An athletic opening bowler with a curious, idiosyncratic action, Chatara takes the ball away from the right-hander at decent pace and is Zimbabwe's key strike bowler. His maiden Test five-wicket haul set up a famous victory over Pakistan in 2013.
New Zealand will face South Africa in the semi-finals while Australia play India in the other match.
It could have been so different, though, had Marlon Samuels held a the catch just three balls in which would have sent Guptill back to the pavilion.
Guptill also survived two lbw shouts, but New Zealand captain Brendon McCullum had less luck at the other end as he fell for 12 runs.
Kane Williamson had put on 33 before falling to Andre Russell, whose wide delivery ended up with Chris Gayle at short cover.
Meanwhile Guptill was moving towards his half-century and reached it with a single from the last ball of the 20th over to put New Zealand on 105 for two.
His ton had been put together with a steady succession of fours but his first six arrived in the 36th over as he carted Darren Sammy to wide long-on.
Guptill was perhaps guilty of ball-watching when Ross Taylor was run out for 42 but, despite the fact the mistake would likely be overlooked due to his heroics, he made sure to atone for it by reaching his second 150 in ODIs with a single off Sulieman Benn.
Corey Anderson was then caught by an off-pace delivery from Russell, shuffling across to pull the ball across to Gayle at midwicket for 15.
Guptill's double-ton was within reach and he wasted no time gunning for it, achieving his personal best of 192 with a four off Russell before partner Grant Elliott was dismissed on review.
Guptill ignored that disappointment to fire a four that brought him to 199, going on to drill Russell's first delivery of the 48th over to long-off for a four that made World Cup history.
Luke Ronchi departed for nine but Guptill held firm hitting a six which ended up on the roof of the stadium in the final over to wrap up his stunning innings.
In reply, the West Indies stuttered, with Johnson Charles out for three in the second over before Lendl Simmons departed for 12 as they rocked on 27 for two.
Samuels (27) applied a steadying hand with the free-hitting Gayle (61), but when the former was caught brilliantly by Daniel Vettori with a one-handed catch on the boundary, wickets again started to fall at regular intervals.
Denesh Ramdin was the next man put, lbw by Boult for a duck before Gayle was clean bowled by Adam Milne.
Sammy hung around for 16 balls for his 27 but after he and Jonathan Carter (32) were dismissed, West Indies were left hanging in on 173 for seven.
Russell (20) and Jerome Taylor (11) put up little resistance with Jason Holder the last man out for 42.
