ROCK OPERA (4) was prominent from the outset when fourth over 1200m at Doncaster last time out. Backmarker who keeps coming. Will be tough to stop. WEN MOON (5) missed the placings two starts back when resuming then ran a better race and finished 1.5 lengths away in fourth last time out over 1000m at Musselburgh. Worth noting Andrew Mullen goes aboard. Must raise the bar but a big run is on the cards. BYZANTINE EMPRESS (13) has a moderate winning strike-rate but performed well when returning from a break last time at Haydock Park, finishing third and only one length from the winner at the end of 1410m. Steps up a level but she is up to the task. INGLEBY ARCHIE (16) bounced back last start and scored by a head over 1000m at Beverley. Has his share of ability. Hard to beat again in this suitable race.
