EL TREN BALA (5) gets a change of rider and has been freshened up since finishing seventh over 2000m at this track last start. Expected to bounce back. CECIL SMITH (4) stepped out on his debut over 1400m at San Isidro five weeks ago and finished eighth, beaten 4 lengths. Likely improver and worth following up. ALPACOR (9) is a two-start maiden who resumed from a spell last start and was beaten 6 lengths when sixth over 1300m at this track. Should progress from that last outing and poses a genuine threat. EL LOUVRE (7) has not raced since his debut on September 28 over 1600m at San Isidro when he finished eighth, beaten 29 lengths. Can improve sharply.
