Pretoria - For the second time in three Sunfoil Series matches, the Van Wyk brothers put in telling contributions to give the Dolphins the upper hand.
Two weeks ago, Divan and Morne van Wyk became just the second pair of brothers - after Gary and Peter Kirsten - to score centuries in the same innings of a first-class match in South Africa.
On Friday they both scored half-centuries against the Titans to make up for the fragility of the batting line-up around them, taking the Dolphins to 314 for six at stumps on day two to give them a first-innings lead of 47.
While Divan marshalled the top order, scoring 87 in the midst of a slow leak of wickets, Morne kept the lower order ticking over and went to stumps unbeaten on 76.
In the middle of those two passages, the pair shared a stand of 70 for the fifth wicket that put the Dolphins back on track at a time when they were in danger of failing to secure a first-innings lead.
The Dolphins began the day on 51 without loss, but had Imraan Khan (36) caught behind in Ethy Mbhalati's first over of the day and then lost Khaya Zondo to the same Mbhalati spell.
With Cody Chetty and Daryn Smit both failing to capitalise on starts, the Dolphins then found themselves on 149 for four before the Van Wyk brothers led the resurgence with that crucial partnership.
Divan was finally bowled by Roelof van der Merwe, who then inflicted the same dismissal on Andile Phehlukwayo, but Morne found a willing partner in Calvin Savage (36 not out) and the pair added an unbroken 81 at a good pace before bad light brought the day to a premature end.
