"I think if I am concentrating on training him 100 per cent and getting him as good as I can have him then there is a danger I might only drive him at 85 per cent," admits Purdon.
"By having Nat drive him I can do my job training the team and she can do her job driving them.
"And she is a very good driver, not just at Menangle but on any track."
While the pair train together, Purdon has driven Lazarus in almost all his 44 career starts, including his wins in the Inter Dominion, two New Zealand Cups, Hunter Cup and Victoria Cup. But Purdon in the stables working and Rasmussen in the sulky has been a powerful one-two punch at Menangle before.
Rasmussen partnered the then stable star Have Faith In Me when he nosed out Lennytheshark in the Miracle Mile two years ago in an Australasian record 1:47.5 and she owns the two fastest winning mile times down under, as she was also in the sulky when Adore Me paced 1:47.7 winning the Ladyship Mile three years ago.
She will drive the stable's best chances in both the Ladyship Mile and NSW Derby.
With the driving off his plate Purdon can now concentrate on getting Lazarus back to his best, or as close as he can get him.
He was surprised when what he thought was a slight bug last week — and Lazarus was twice passed clear to race by vets — troubled Lazarus so much in his prelude defeat.
"We had his blood taken last week and had him scoped but I think at this level it exposed how even being the smallest bit off your game you can get beaten," Purdon said. "But there have been some real positives since the weekend.
"He seems well in himself and his blood report we got back today [yesterday] was definitely better.
"We had rain overnight on Monday which will help too because it settles the dust, which not many of ours are used to, or like. But I won't really have a good idea of where he is at until I work him on Thursday morning.
"The way he looks, his blood and the way he is handling himself I think I can get him back to something like his peak for Saturday.
"But it has been a long summer, he has done a lot of travelling and now had this little setback.
"So I will be doing my best. But will he be at the same level as he was when he won the Inter Dominion in Perth? I hope so, but it is hard to be certain. Put it this way, I wouldn't give you a money-back guarantee."
Those words alone, coupled with almost certainly copping the toughest run in a race that has six group-one Menangle winners against him, means Lazarus could start closer to $3.50 than his opening NZ TAB quote of $2.20 come Saturday night.
Meanwhile, stablemate Heaven Rocks has been sold to clients of US trainer Ross Croghan, joining Have Faith In Me and Waikiki Beach as huge name All Star pacers exported to the States.
