Whether CD skipper William Young takes the new ball, due after five overs, or not will depend on the shield's leading wicket taker this summer, Ajaz Patel, finding traction on what is stubbornly becoming a traditional benign batting track.
The Heinrich Malan-coached Stags felt they had got enough runs out of the strip, after injured opener Ben Smith scored 66 runs to help boost the overnight total of 318-7 with the help of tail enders Patel and Rance while No11 Blair Tickner was unbeaten on eight runs.
"It's now going to be a typical McLean Park track so it's taking a little bit of turn on which Ajaz will be able to find some overs but, overall, it's very flat so we'll give it a good go," he said of the left-arm orthodox spinner who claimed 1-56 from 26 overs, including eight maidens yesterday.
The chances are Papps may not have slept very well, four runs shy of his century but Rance laughed it off last night.
"He's an experienced batsmen so, you know, those things shouldn't worry him too much.
Yeah, he's played a very good innings," he said as Papps is at the cusp of his 30th first-class ton.
He lauded Smith for his contribution after taking a blow in the box from a Hamish Bennett delivery on Wednesday before returning later that day to resume batting.
Wellington paceman Matt McEwan took a career-best 6-81.
The Stags have claimed three batting bonus points in the first dig to Firebirds' one and pipped the visitors 4-3 in the bowling department.
