South Africa's Richard Levi hit the fastest ever Twenty20 century in the Proteas' victory over New Zealand in Hamilton.
The 24-year-old passed 100 after just 45 balls and went on to reach an unbeaten 117, a knock that also included a record-breaking 13 sixes.
Levi was making just his second international appearance as the tourists levelled the three-match series by claiming an eight-wicket win.
