Caloundra trainer Stuart Kendrick's roller coaster week continued when his mare Copywriter scored an upset win at Doomben.

It was Kendrick's sixth win in a week which was soured by an injury to his top three-year-old Eric The Eel in the Caulfield Guineas on Saturday.

"It was terrific to be part of last Saturday at Caulfield with a great atmosphere and a big crowd," he said.

"Unfortunately it didn't carry over to Eric The Eel but he will be back next year for another try."

Copywriter ($16) finished powerfully to beat the short priced favourite Desert Man ($1.22), who was later found to have bled, in a Class 5 Plate (1200m).

The mare carved out the 1200m in 1.08.88 which would win most stakes races at Doomben.

"I might have to think about a black type race on that time," Kendrick said.

"She has been racing well but I thought Desert Man would be too quick. But as everyone keeps saying, racing is a funny game."

Talented filly Epicurious confirmed her form around some of the state's best three-year-olds with an easy five lengths win in a maiden.

Epicurious had been racing in top three-year-old company including a recent third behind smart gallopers Profit and Guntantes.

Trainer Louise White said Epicurious might have finally learned what racing was all about.

"She has been doing a lot wrong against the better three-year-olds but she had a lovely run today and showed what she can do," White said.

The decision to geld expensive horse Group Think ($1.80) could pay big dividends after he broke his maiden.

"He is still a bit coltish but that will go. I really like this horse and I think he will be more than handy at 2000m," co-trainer Toby Edmonds said.
