Mangaroa Flo Jo's lengthy trip to Wellington has been rewarded with racing's ultimate prize for a mare - a black type victory.

The Cambridge six-year-old posted the sixth win of her career in the Gr.3 L.J. Hooker Sales Team Manawatu Breeders Stakes.

"It's the fittest she's ever looked and we were chasing black type, this was as good a chance as she was ever going to get," said Graham Thomas, who prepares the daughter of High Chaparral with Nick Smith.

Mangaroa Flo Jo was ridden by Anna Jones and they settled off the pace before picking up ground with 800 metres to run.

They challenged soon after straightening and the mare held a strong gallop to the post for a comfortable victory.

Mangaroa Flo Jo had finished at the tail of the field at her previous appearance under apprentice Jordan Nason when resuming after a break, but Thomas said she had excuses.

"That was on a good track at Te Rapa and she couldn't keep up early," he said. "When Jordan let her go she nearly got put over the fence so she had an excuse."

Trentham runner-up Classic Touch was allowed to stride to the front 800 metres from home and she fought on gallantly in the run home.

Bellas Delight took third and the well-supported Wildflower was doing her best work late for fourth.
