QUINTESSENTIAL (4) comes off a big run when second in a quick 18.47 at this track over 318m. Hot time latest and looms as the one to beat. PORTLAND MARK (8) boasts a strong record this course with nine wins and seven minors from 23 tries. Hit the frame latest (18.72) when third at this track in a SPECq. Suited here and expected to run well. LION'S DEN (2) looks close to another win after finishing second last time (18.50) at this track. Has a good record here including five wins. Didn't win last time but still ran one of the quickest times on the card. Must be included in calculations. HADWIN BALE (7) was well fancied last time on the back of some sparkling form, which included a two-start winning streak, but could only manage sixth (21.77) at Cambridge Raceway. Can atone.
