ESTERIOS (5) has switched yards since finishing fifth two-and-a-half weeks ago over 1400m at this track. Key runner who will be tough to beat. SOBERANO REY (9) was safely held when third last time out over 1900m at this track, beaten 10 lengths. That followed a win at Valparaiso Sporting Club at the previous outing. Beautifully placed and is sure to play a pivotal role. NGANNU (11) is usually thereabouts but finds it hard to win, with only one victory from 25 starts. Again tasted defeat last start when fifth over 1900m at Club Hipico De Santiago, beaten 9 lengths. Must raise the bar but a big run is on the cards. AQUIMBAO (1) finished second last time over 1400m at this track when resuming from a spell, beaten 0.3 lengths. Will trim down second-up. Likely improver with top-three claims again.
