IN a huge but not unknown upset from these quarters the Fozzy Stack-trained newcomer Hermana Estrella defied odds of 50/1 to make a winning debut in the Group 3 Coolmore Stud EBF Fillies Sprint Stakes, marking herself out as a filly of major potential.

Beforehand, the first pattern race of the season for juveniles appeared to revolve around Contarelli Chapel whose hugely impressive debut at this track last month saw her returned as the 2/7 favourite. However, the market leader floundered on the soft ground and could only manage fourth as Hermana Estrella, in the colours of David Keoghan, turned in a tremendous effort.
