South African spinner Colin Ackermann claimed a new Twenty20 world record on Wednesday when he took seven wickets for just 18 runs in the Vitality T20 Blast.

The 28-year-old, playing for Leicestershire, took the wickets of Michael Burgess, Sam Hain, Will Rhodes, Liam Banks, Alex Thomson, Henry Brookes and Jeetan Patel in his side's 55-run over Warwickshire at Grace Road.

Malaysian bowler Arul Suppiah held the previous world record when he claimed 6-5 for Somerset against Glamorgan in 2011.

"It hasn't really sunk in. I'm sure I'll remember this game for a long time," the Ackermann said after the visitors, chasing 190 to win, were dismissed for 134. "I think it's the first time it's really turned at Grace Road. I tried to use my height and get a bit of bounce.I wanted to get the batters to hit into the bigger side of the field and mixed up my pace."

"Never in a million years (did he think he would set a world record). I'm a batting all-rounder," he added.
