Evan Flint, the Newlands curator, said on Thursday that the number-four pitch on which the encounter will be played, might just be a touch slow and has less grass on it than he would have wanted.
It might even favour the spinners, he said.
A feature of the Momentum One Day Cup competition this season has been the excellent work by the slow bowlers in the middle-period. Peterson has been a standout-performer for the Cobras, and he has received excellent back-up from SA Engelbrecht.
The management team has worked hard on erasing the bad habits in the field, and on reducing the number of extras.
There were 19 extras in the nail-biting win against the Chevrolet Warriors on Sunday.
The Dolphins will have licence to play with gay abandon on Friday, as they have nothing to lose.
The hosts enjoy an 8-point cushion at the top of the table, which means The Unlimited Titans will have to beat the Chevrolet Warriors at SuperSport Park in Centurion to give themselves a sniff of overtaking the Cobras.
Peterson said on Thursday that a century by one of the top-order-batsman is a critical component of their performance.
He is very up-beat about the ability of the attack to restrict opponents, but the fielding will have to improve significantly, he added.
Justin Kemp, a senior player, and Paul Adams, the coach, were both critical of the quality of the fielding after the 4-wicket win against the Warriors at Paarl on Sunday.
The Cobras squad is: Justin Ontong (capt),Sybrand Engelbrecht, Beuran Hendricks, Justin Kemp, Rory Kleinveldt, Richard Levi, Dane Paterson, Robin Peterson, Andrew Puttick, Omphile Ramela, Mthokozisi Shezi, Mohammed Vallie, Stiaan Van Zyl, Dane Vilas.
