Trainer Bryan Guy struggles to remember a horse having unlucky runs in so many different ways as Alignment who takes on stakes class for the first time at Eagle Farm.

Alignment is one of two fillies in the field for Saturday's Group Three Grand Prix Stakes (2206m) at Eagle Farm.

Guy said he did not like making excuses for beaten horses but things were getting annoying with Alignment.

"All trainers have horses who are unlucky in races and I have had plenty," Guy said.

"But I usually try to erase those runs from my memory or you drive yourself crazy."

Guy, who trains in partnership with his son Daniel, said there was no doubt Alignment should have finished a lot closer at her past three starts.

He said she had been unlucky in totally different ways in those three runs.

"She got pushed very deep at Eagle Farm but still ran on to finish third," Guy said.

"Then at her next start she was travelling well when the horse in front of her tired quickly and dragged her back through the field. By the time she ran on for fifth the race was nearly over.

"Then last start she got caught deep in a 2000 metre race at Doomben and ended up leading which certainly isn't her go. In fact we had two in the race and they ended up cutting at each other in the lead."

Guy said the key to Alignment was getting cover and then getting clear in the straight.

"Eagle Farm suits her and dare I say she deserves some luck," he said.
