Harry Brook finished Friday with a Test average over 100 after racing to 184 not-out on day one of England's second Test in New Zealand.
Brook, 24, came to the crease with England in a dire position, sitting at 21-3 after Zak Crawley, Ben Duckett and Ollie Pope all found themselves dismissed in a combined 39 deliveries.
New Zealand quick Matt Henry took the first wicket, finding the outside edge of Crawley in the fourth over, and after that one went through to Tom Blundell with the gloves on, Pope edged to third-slip off Henry's very next over.
Michael Bracewell snagged another catch at third slip when Tim Southee found Ben Duckett's edge, leaving the visitors in a precarious position, but they were just getting started.
With Joe Root down the other end, Brook showed no fear, maintaining a strike rate near 100 his entire innings as he blasted his way to 100 off 107 deliveries.
It was his fourth century from nine Test innings, and while he still has his sights set on his first double-century, he continued to push the tempo, reaching stumps at 184 not-out off 169 deliveries.
Root played the steady hand, climbing his way to 101 not-out off 182 deliveries, with just 28 of his runs coming from boundaries (seven fours). In contrast, 126 of Brook's runs have come through boundaries (24 fours, five sixes).
The sides were only able to get through 65 overs before the rain arrived, forcing stumps to be called early with England at 315-3.
Harry making history
Brook has burst onto the scene as arguably the most exciting young Test batsman in recent years, and his strike rate of 99.38 is the highest in Test history for players with at least 200 runs in their first five Tests.
He currently has 807 total runs – at an average of 100.87 – giving him a chance to overtake Sunil Gavaskar (912) and Sir Donald Bradman (862) as the only batsmen in Test history with more runs in their first six matches.
Root moves one step closer to Cook's record
Root's century was his 29th while wearing the Test whites for his country, and he took one more step towards reaching Alastair Cook's record of 33. Root is now six centuries clear of third-placed Kevin Pietersen.
