The $487,000 prize took her earnings to $657,000. She has won six from 16 and looms as a Melbourne Cup chance.Lonhro collected his fourth group I of the season and sixth in his career with an easy win in the Queen Elizabeth Stakes (Aust-I). At his final 4 year-old start, the black son of Octagonal advanced his earnings beyond $3.4 million, gleaned from winning at 18 of 25 starts.Lonhro's season sign-off from Pentastic and Republic Lass wasn't enough to see him seriously challenge Northerly as Australian Horse of the Year, despite the latter's three fall defeats in Sydney.
