De Bruyn plundered a 49-ball century as Tuks, who had won the toss, slammed 205 for four in the T20 match against the University of Liberal Arts, the Bangladesh representatives in the Varsity World Cup.
The Tuks openers, Aiden Markram (22) and Gerry Pike (34), provided the stable foundation for De Bruyn to launch in the closing overs.
The 21-year-old finished on a phenomenal 137 not out off just 60 balls, with 12 fours and eight sixes, as he took 51 runs off the last three overs, including 24 off the final over bowled by medium-pacer Abdullah Imran.
Far from being wild hitting like a cur feeding frenzy, it was a clinical, ruthless display of batting by De Bruyn.
The Tuks bowlers then dished out a similarly efficient display as they restricted the University of Liberal Arts to 91 for seven, clinching a 114-run victory.
New-ball bowler Corbin Bosch (3-0-16-2) and lanky off-spinner Ruben Claassen (4-0-22-2) were the most successful bowlers, but everyone contributed. There were also wickets for seamer Johan Wessels and left-arm spinner David Mogotlane, but none of the eight bowlers used conceded more than six-an-over.
Tuks play England’s Leeds Bradford MCC today, before finishing their round-robin against Jamaica Inter-Collegiate Sports Association on Wednesday.
The West Indians won a low-scoring encounter against Leeds Bradford yesterday, so the hosts are bound to come out firing against Tuks today.
