SUMATORIA (7) is close to breaking through after two consecutive placings, the latest coming when second over 1000m at this track. Looks well placed this line-up so expect another big run. LA CHOPER (3) disappointed when 7 lengths back in sixth last time over 1000m at La Plata. Kept fresh for this. Key runner on her best form. REINA SIN TRONO (8) finished one length from the winner in fourth last start over 1000m at this track, an improvement on her fifth at La Plata the run before. Suitably placed so anticipating a big run this time. AMANTE DESPECHADA (4) finished third last start over 1000m at this track, beaten one length. In the right race and is sure to prove hard to beat.
