"I've got a long way to go yet," he said. "Things like that are for other people to say, not for me to worry about. As far as I'm concerned those guys [Knott and Stewart] are legends of the game and I have a long way to go to class myself alongside them. Fingers crossed maybe one day I can say 'yeah I had a good influence on the team', but right now I'm just taking each game as it comes and performing as best as I can."
Prior said he looked up to Knott and Stewart as two of the best stumpers to pull on the whites.
"Yeah, I have done a bit of work with Knotty. And as you say you look at these guys and as you know Stewy has been a mentor of mine for many years, so you look at the guys, the stats and the games they played and all those things. Yeah, they're distant goals but I made the mistake of looking too far ahead once before and I'm not going to do that again. I take each game as it comes and as long as I'm performing well for the team that's all I'm worried about."
He and Steven Finn (24) added 83 runs for the eighth wicket in quick time after lunch, which pushed England past the 400 mark.
Prior was eventually out to a cheeky reverse sweep from the part-time off-spin of Kane Williamson and in typical Prior style he was simply trying to add to the team total rather than play his way to what would have been his seventh test hundred.
