Durban - Marchant de Lange continued his good form with the ball, but the Dolphins had the better of the first day of their Sunfoil Series clash with the Titans at Kingsmead.
De Lange followed up his six-for in his last outing by recording figures of 3 for 75, but the Dolphins batsmen still had an excellent day as they put up a total of 293 for four - despite losing the toss and being asked to bat.
The score was even more impressive given that 25 overs were lost to bad weather and poor light, meaning the hosts scored at more than four runs to the over.
After De Lange had removed Divan van Wyk in his third over of the day, the Dolphins took control with Imraan Khan returning to form with a half-century as he put on 129 with Daniel Sincuba for the second wicket.
Farhaan Behardien was the man to make the breakthrough as he dismissed Khan for 60, and when De Lange had Sincuba caught for 41 the Titans were back in the game.
However, from 152 for three the Dolphins quickly regained control, with Vaughan van Jaarsveld scoring 67 from just 80 balls as David Miller played a steadier innings.
After Van Jaarsveld fell to De Lange, Miller continued to bat serenely alongside captain Morne van Wyk, with both batsmen unbeaten on 42 when bad light brought a premature end to the day.
