Well-travelled jockey Kevin Kalychurun celebrated a career best result at Riccarton where he earned his first win at black type level.

Now based at Riverton, the 31-year-old made the breakthrough aboard the Sally McKay-trained Showemup in Saturday's Listed New Zealand Bloodstock Airfreight Stakes.

"It's something special to me and for the trainer and connections as well," said Kalychurun. "I know the filly and she's been close before so it's a well-deserved victory."

He was referring to the Showcasing filly's Listed placings in the Gore and Dunedin Guineas.

Kalychurun said he had been a little worried earlier in the week by Showemup's barrier, but any concerns were erased as soon as racing got under way.

"We were drawn one and on a heavy track they often need to be wide, but it was a different racing pattern here and the fence was the place to be.

"We were in behind the leader who rolled off and my filly was too good."

Showemup won by three quarters of a length from the northern filly Grand Soleil with Dontpokethetiger third.

A native of Mauritius, Kalychurun began his New Zealand career in the north and had spells with Graeme Rogerson, Donna Logan and John Wheeler before establishing himself in the southern ranks.

Meanwhile, Tommy Tucker gave weight and a sound beating to his rivals in the Listed Christchurch Casino Easter Cup.

The Brian and Shane Anderton-trained eight-year-old made light of his topweight of 60kg to account for Bloodstream, who was in receipt of seven kilos.

Tommy Tucker was ridden as usual by Jacob Lowry and tracked the leaders near the fence before dashing clear in the closing 200 metres.
