"When I rang her to offer her the ride she was pretty stoked and I got a real thrill out of that myself. So I am glad to give her the opportunity."
Rogerson is the granddaughter of training legend Graeme Rogerson and while she has only seven career winners here she has plenty of experience.
"I can see Deerfield coming across to lead and Frodo [Tavi Mac's stable name] sitting in the trail and a five-horse field there shouldn't be too many traffic concerns."
With Tavi Mac now carrying just 58kg, 0.5kg more than Deerfield, anything like his best should see him win and Sharrock is confident that will be the case.
"Hey, it is a $32,500 race after all and we have far bigger targets so he isn't screwed down but the way he trialled a few weeks ago and has galloped since I think he can win," confirms Sharrock.
Sharrock finishes his personal best season with 54 wins and more than $1.1 million in stakes going into tomorrow and believes he can add to that total even without Tavi Mac's contribution.
"I actually think my other one in that race, London Express, is the danger to Frodo with Callum Jones on taking her weight down to 52kg."
He can't split his two hopes in the feature of tomorrow's meeting at Otaki and the last black type race of the season, the $50,000 Ryder Stakes, in which he has Yeaboi (R5, No2) and Catsacharmer (3), both unbeaten.
"The filly Catsacharmer has been really good in both her runs and Danielle [Johnson] is coming down to ride her for just about her only ride for the day so I expect she will start favourite, which she should," explains Sharrock.
"But the boy [Yeaboi] was very good last start and has only kept getting better so I don't think there will be much between them."
Sharrock suggests Herald readers back Butler three weeks ago and those who followed his advice would have got a winner and he says to back him again in race six tomorrow.
"He is going well and Hazel [Schofer] is riding so well he will be very hard to beat."
The open 1600m tomorrow looks the betting race of the day.
The event will bring together some of the warriors of winter racing in a race that could become far tougher than 1600m might usually suggest on a heavy11 track.
