UNTAPPED Testa Rossa three-year-old gelding Heart Testa’s unbeaten record goes on the line when he tackles the tab.com.au Handicap (1300m) at Warwick Farm on Villiers day tomorrow.

The Chris Waller-trained gelding has looked sharp in each of his three win to date including his recent all-the-way win in a Bm80 at Rosehill Gardens over 1300m on December 8.

Heart Testa will need to continue his steady rate of improvement given that he will shoulder a crushing topweight of 59kg and jump from a wide barrier.

On the plus side, the solid bound that has formed between horse and rider remains unbroken with Kiwi whiz-kid Jason Collett in the saddle again this weekend.
