Certify: Worked surprisingly well
Mahmood Al Zarooni does not expect Friday's Barrett Steel May Hill Stakes at Doncaster to be a penalty kick for his unbeaten filly Certify.
Connections revealed that the filly was something of a surprise winner when she made an impressive debut at Newmarket in July but she proved that was no fluke when following up on much quicker ground in the Sweet Solera Stakes.
The form was given a significant boost when the runner-up Sky Lantern landed last weekend's Moyglare Stud Stakes at the Curragh and Certify is a short-priced favourite to complete her hat-trick in Group Two company on Town Moor.
"The filly is in good form and doing everything right at home. I think she is a bit stronger than her last race and hopefully she has improved," said Al Zarooni.
"It is not going to be easy for her. It looks a tough race and we will find out how good she is.
"Before she ran on her debut, you would say her work was average, but after that she woke up a bit at home and improved every week.
"She is not a filly who works really well at home, but her last piece of work was actually very good.
"Now I am a bit worried because when she was not working well she was running well on the track, so hopefully now it is not the other way around!
"She's a light filly and I think the ground will be fine for her."
Second in the betting is the Mick Channon-trained Ollie Olga, but her participation is in some doubt.
She has won each of her three starts and beat Sky Lantern at Goodwood last time, but appears to have come into season at the wrong time.
Channon said: "We've found out she's in season this morning, which is a nuisance, and I'm not sure she's going to run.
"We'll see what's happening later today and if she doesn't run, she'll probably go for the Fillies' Mile."
William Muir's Purr Along was a Group Three winner in France last month and the trainer is looking forward to seeing her line up at Doncaster.
He said: "It's a good race, but ours is a nice filly.
"For a small yard like ours it's great to have a horse like her and we'll go to Doncaster and enjoy the day no matter what happens.
"Since the first day she worked, I knew she was very good and I don't think she's ground dependant, that's the beauty of her.
"She has really thrived since Deauville, she looks a different filly.
"We're living the dream with her and whatever happens, I think she's a filly for next year."
Tuttipaesi has joined Marco Botti having won her last three starts in Italy.
The Newmarket-based trainer expects this to be her only start in Britain.
He said: "I've been happy with her since she arrived from Italy.
"She is ready to run and hopefully she can run well, even though it looks a very good race.
"She wore a hood in Italy because apparently she got a bit on her toes when she arrived at the racecourse, so we are keeping that on her.
"The trip will be no problem and this will probably be her only run in Britain as she has been bought by Team Valor to go to America.
"Hopefully she can run well tomorrow, then she will run for us in America on October 5 and then stay over there."
Richard Hannon's Newmarket handicap winner Light Up My Life is one of the outsiders, but the champion trainer can see his filly running well.
He told his website www.richardhannonracing.co.uk: "She might look out of it on ratings, but Eddie Ahern, who rides again, was impressed with her when they defied a big weight in a nursery at Newmarket, and we don't see the extra furlong being a problem."
