THE battle for the trainers' championship continues unabated with the leading contenders landing a winner each yesterday. Leader Patrick Biancone saw his faith in griffin Deauville (5-2 favourite) fully vindicated when the youngster powered through under an excellent Eric Legrix ride to take the second event on the card. One race later and Wong Tang-ping trimmed the Frenchman's advantage back to the original two-winner deficit going into the meeting. He did that courtesy of Today's Special (7-2 favourite) who got up close to home in a Class Six event under Gary Stevens. John Moore, also two adrift when proceedings opened yesterday, pulled back one when Joint Account (7-1) just got home in the Queen's Silver Jubilee Cup over 2,000 metres. Given a heady ride by Tony Cruz, Joint Account won on a bob of the heads with 35-1 outsider Assegai, who has now run a short head second at his past two starts.
