Bryony Frost rides out her claim with easy winner at Kempton on Monday

RISING STAR Bryony Frost reached yet another milestone at Kempton on Monday.

The top jock rode out her claim when steering Marienstar (5-2f) to a runaway success over fences, giving her a 75th career winner.

The 23-year-old made all the running aboard the Neil King-trained mare in the Weatherbys General Stud Book Mares' Handicap Chase.

The pair breezed clear in the home straight to register a 22-length success, and Frost will now receive a 72 hour 'grace' period before her 3lbs claim is removed.

The jockey enjoyed another of her finest hours at Kempton when winning a Grade 1 aboard Black Corton last Boxing Day.

Frost said: "What a girl Marienstar is. The only worrying part was to try and get in front at the start. She jumped fence to fence.

"I'm a professional now. I've flown the nest.

"It's now a bit of a daunting time, but I've got Paul Nicholls and Neil King behind me.

"When you have those teams behind you, they fill you with confidence.

"Driving up I was thinking 'this is the place I've had some of the best days of my life' and obviously Black Corton stands out."
