POLAR THUNDER (6) finished out of the money two starts back then was beaten 3 lengths when fourth in a 1000m contest at this track four weeks ago. Best figures measure up nicely. Sure to run well. CHOLADEF (3) finished out of the money two starts back then was beaten 4.5 lengths when eighth in a 1200m contest at La Plata a month ago. Meets some better types this time but a big run is on the cards. VICTORIOSA AGUS (5) resumes from a spell of 11 weeks after closing off last preparation with three consecutive minor placings. Has a decent record at this trip with five minor placings from six tries and should be involved in the finish. MISS ROBERTS RIM (2) was unplaced two runs back when fresh from a spell then again missed the frame last start over 1000m at San Isidro, beaten 6 lengths into seventh. Best efforts measure up so worth another chance.
