Heino Kuhn scored his second successive century as the Titans secured a South African One-day Cup final place against Cobras with a five-wicket win over Dolphins on Tuesday.
Fresh from scoring 104 last Friday in the final league round to earn the Centurion-based franchise a play-off spot, the opener struck 102 at Kingsmead.
Hosts Dolphins won the toss in Durban and made 237 in 49.4 overs while Titans reached 240-5 with nine balls to spare.
A patient Kuhn faced 117 balls during 189 minutes at the crease and his knock included one six and only five fours while unbeaten middle-order batsman Graeme van Buuren (47) also impressed.
No one in a Dolphins attack that included former England fast-medium bowler Graham Onions excelled with Khaya Zondo (1-15) returning the best figures.
Middle-order batsman Daryn Smit (53), opener-cum-wicketkeeper Morne van Wyk (48) and lower-order Kyle Abbott (43) performed best with the bat for Dolphins.
CJ de Villiers (3-40) was the leading wicket-taker in the play-off and Shaun von Berg (2-41) made a valuable contribution.
Cobras will seek a hat-trick of victories over Titans this season when they host the day-night final Friday at Cape Town Test venue Newlands.
The Cape outfit won by two runs away and by four wickets at home when the teams clashed in the mini-league phase.
