Top Notch put up a polished performance to win the GL Events Owen Brown Graduation Chase at a very foggy Ascot.
A field of five went to post for this two miles and five furlong contest.
Sizing Codelco and Solstice Star took the runners along with a healthy early lead.
Racing down the back straight and with a circuit raced, the field were bunched, with Sizing Codelco still leading Solstice Star, while Caid Du Berlais and Top Notch were next, ahead of Hammersly Lake.
Sizing Codelco pressed on turning for home, with Top Notch and Caid Du Berlais giving chase, followed by Hammersly Lake.
Top Notch came to challenge two out and forged into the lead racing to the final fence, jumping it well.
With the jumping completed, Top Notch showed his superior speed and he held on comfortably from a resurgent Sizing Codelco and the staying on Hammersly Lake in third.
The Nicky Henderson trained 5 year old was completing a hat-trick of wins over fences and this performance suggested that the JLT Novices’ Chase could well be within his remit come the spring.
