TRAINER Matt Heilbronn s Open My Mail is the definition of a chaser in form. The three and a half year old has been more than serviceable over his 60 plus start career. He has found a new level in the past month, winning four of his last five at varying venues. Off the back of a pair of Thursday night 500 metre wins and a short course triumph, Heilbronn brought him to a tough fourth/fifth grade 431 metre event last Saturday. The dog is not known for his box manners but has a powerful burst down the back. On the way home, he needed every bit of it as he can rattling four wide on the home turn to run over the top of them.
