Graeme and Debbie Rogerson believe their remarkable strike rate with the younger members of their Tuhikaramea operation could have been even better.

The husband and wife team have won 11 of this season’s 13 two-year-old races and saddled the runners-up in the other two.

“It was disappointing that the ones that got beaten had no luck,” Graeme Rogerson said. “We’ve got a good system.”

Jacquetta has joined her stablemate and Listed Wellesley Stakes winner Maritimo as a black type performer with her comfortable victory in Saturday’s Listed Barneswood Farm Agistment Welcome Stakes at Riccarton.

The daughter of Keeper posted her third victory in four starts on the course when she defeated Peach Cove and Outlaw Kate.

“She’s a lovely filly, she doesn’t pull and only does what she has to,” said Rogerson, who also bred and part-owns Jacquetta.

Rider Chris Johnson urged her to the lead on straightening and she never looked in danger of disappointing the favourite backers.

“She hit the front a long way out and she’s still pretty green, but she held them quite well and won nicely,” he said.

The stable also won the previous event, the Mohua Premier Handicap, with Cosmic Cube, who had no favours when unplaced in Wednesday’s Gr.2 Coupland’s Bakeries Mile.

“Another horse ran into him and pushed him onto the heels of another one,” Rogerson said. “He’s a pretty good horse.”

Cosmic Cube turned his luck around on Saturday when he powered away over the closing 200 metres to score by four lengths from the southern pair of El Chico and Go Go Dingo.

“He’s a nice horse and was down in the weights – he proved how good he is today,” rider Matt Cameron said.
