KAISHO (5) turned in a solid first-up effort at Hakodate then wasn't beaten all that far last time when seventh at Sapporo over 1200m. Likely improver with strong prospects. RIO CHRIS HARLEY (18) was a most impressive maiden winner over 1000m at this track last time out when resuming, scoring by 2 lengths. Kiwamu Ogino was in the saddle on that occasion and retains the mount. Capable of making it two on the trot. FANCY FRILL (9) returns after a spell of five months. Started the last campaign impressively when in the placings over 1000m at Kokura Dirt. Looks a strong top-three prospect. SHANKS (14) finished third last start at the first run back from a spell over 1000m at this track, beaten a long neck. Fitter for that run. Likely improver with solid claims.
