UNCHARTED (9) ran well on debut last start to finish second over 1000m at this track in a tougher race. Tricky draw to overcome but he is worth following up. QUALITY IMPULSE (4) stepped out on his debut over 1400m at this track four weeks ago and finished fourth, beaten 21 lengths. Better for the run and can improve sharply. OTHELO (5) is a two-year-old colt on debut from the stable of Luiz De Gonzaga Esteves. By Sangarius from Hammana. Bold showing expected. TUNGA (10) is appearing for the first time. By Alpha and comes from the Luiz De Gonzaga Esteves stable. Pay to watch for any positive betting moves.
