Key To My Heart goes for Grade One glory Key To My Heart takes a huge step up in class in the Belmont Oaks today. The Galileo filly caught the eye in an Oaks trial at Naas last month, but will now make the transition from Listed to Grade One company in the hands of Wayne Lordan. Trainer Aidan O'Brien said: "The filly is in good form and won well for Donnacha (O'Brien) at Naas. "She's in good form and is out there already." Sistercharlie is the hot favourite for the mile-and-quarter race at Belmont Park, while former Richard Hannon inmate Grizzel takes the plunge for Canadian trainer Michael Doyle and is on a hat-trick.
