RICHARD Hannon believes the form of Tiggy Wiggy's last two runs suggest his lightning-fast filly is still improving ahead of the Connolly's Red Mills Cheveley Park Stakes at Newmarket on Saturday.

Collingbourne Ducis trainer Hannon is prepared to make hay while the sun shines, and her six-length win in the Super Sprint at Newbury and her superb victory in the Lowther Stakes at York would indicate she is still on the march.

"The way to evaluate her is her races, and her last two have been her most impressive," said the Wiltshire handler.

"She was our first two-year-old runner and we thought she'd go to Kempton and do OK, but she never saw another horse.

"She's very quick and sweet to deal with, but she can be a little bit quirky.

"I've got to be honest and say that I thought they'd gone way too fast in the Lowther, but to her credit she kept going.

"Arguably that was the best fillies' race of the year, they all turned up and ran their race. Her form is unknockable.

"We won't think about the Prix de l'Abbaye until after the race - the Cheveley Park is one of the great races in the calendar and it would be fantastic if she could pull it off."

Tiggy Wiggy has only met with defeat twice this season but one of those was in the Queen Mary at Royal Ascot, when Eddie Lynam's Anthem Alexander held her off - after which Hannon's filly gained her revenge at York.
