O'Brien in Seventh Heaven at Lingfield Seventh Heaven outbattled Architecture to win the Betfred Mobile Oaks Trial Fillies' Stakes at Lingfield. The Aidan O'Brien-trained winner was sent off the 7-4 favourite for the Listed heat but she made hard work of winning in the hands of Ryan Moore. Mountain Bell set the gallop but she had no answer as Seventh Heaven and Architecture emerged from in behind to fight out the finish. Moore had to get serious with Seventh Heaven, though, and while not producing a totally smooth run, the Galileo filly proved a neck too good for her rival. Paddy Power now offer odds of 20-1 from 33s about Seventh Heaven for the Investec Oaks.
