"There's not enough races long enough for him, so Trentham suits him.
"We started looking around for other options a while ago and hopefully he goes well."
The winner of four races, Pop 'N' Scotch boasts an interesting formline for Trentham, having finished runner-up in the 2015 Queensland Cup. He was beaten by Mister Impatience, who won last year's Wellington Cup and will defend his title.
Pop 'N' Scotch further underlined his two mile qualities when he again finished runner-up in the Queensland Cup last July. Most recently, the 6-year-old finished third under 59.5kg over 2200m at the Gold Coast.
"His last run was pretty good and while he can be a little bit in and out, on his day he's pretty effective." Birchley said.
"We may stay on for the Auckland Cup," he said. "There's not much else for him so it could be a good idea to hang around over there."
