The Titans had posted a franchise record 340 for six in their 50 overs, thanks to a century on List A debut by Theunis de Bruyn and a blazing 105 not out off just 67 balls by Farhaan Behardien.
A 35-minute rain delay after the dinner break meant the Dolphins’ target was adjusted to 301 in 42 overs and Van Wyk played a top-class innings, finishing on 121 not out off just 112 balls with 14 fours and two sixes to see them home.
Van Wyk played with a zen-like calm even though the required run-rate began to climb steeply after Vaughn van Jaarsveld was dismissed for a fine 62 off 55 balls.
The promising Khaya Zondo helped his skipper add the finishing touches with his composed 32 off 18 balls as the Titans bowled awfully and fell apart in the field, much as the Dolphins had earlier after winning the toss.
De Bruyn took advantage of the three chances given to him to stroke 108 off 90 balls, while Behardien’s 64-ball century was the fastest ever for the Titans, but both innings were in vain thanks to the profligacy of the bowlers.
