Tobaysure and Don Diego are equal favourites in the Ladbrokes.com.au market for the VOBIS Sires Guineas (1600m) at Caulfield this afternoon.
Tobaysure was a dominant all the way winner at Pakenham last time out and looks suited here while Don Diego was a closing third at Sandown against the race shape. He has been the firmer of the two, both at $3.50, but Don Diego opened $4.
Outside that pair, the horse with the most money invested on the race is Chartres, who $4.20 to $4.50 but has been rock solid since markets opened.
