John Oxx successfully kicked the 2007 flat campaign off at the Curragh on Sunday when Alarazi made a winning debut but he believes his best chance of classic glory this year could come from his fillies.

The former champion trainer issued an upbeat report yesterday on the unbeaten Arch Swing, a 20 to 1 shot for the Stan James 1,000 Guineas, who could have a pre-Newmarket warm-up at Leopardstown on Saturday week if ground conditions are suitable.

"It would have to be on the slow side of yielding at worst if she is to run in the 1,000 Guineas Trial," Oxx declared. "She does like a decent bit of ground and she certainly wouldn't run on anything like we had at the weekend."

He added: "She is in good shape and there were no problems during the winter and spring. The Guineas entries were made in early March and like everyone else with an entry, the aim is to get to Newmarket. She's a pretty obvious contender for it."

Arch Swing followed up her Curragh maiden victory with an impressive four-and-a-half-length success in last September's CL Weld Park Stakes at the same track.

Oxx has three entries for the Vodafone Epsom Oaks including the 33 to 1 ante-post shot Four Sins who is among the 17 left in Sunday's Ennistown Stud Salsabil Stakes at Navan after yesterday's forfeit stage.

However, it is the Kalanisi filly, Hasanka, winner of her sole start at Cork last September, who has been attracting some positive reviews on the Curragh gallops and significantly is already as low as 25 to 1 for the Oaks in early June.

"She has been a little slow to come to hand and it will be the end of April before she will be out. She won a good maiden at Cork and she is a filly we like," said Oxx who also has Timarwa in the Oaks. "She is out of Timarida and is a nice filly but at this stage, it is something of a speculative entry," he added.

"Four Sins wants decent ground. She didn't run at all well in the Million behind Miss Beatrix when it was soft. I put her in at Navan in case they get more sunshine than showers this week but at this stage I would say she is unlikely to run. It's just there's a shortage of mile-and-a-quarter races around at this time of year."

The Oxx team have five entries in the Epsom Derby including Sunday's winner Alarazi as well as Angelonmyshoulder who won his second start on Champion Stakes day at Leopardstown last year.

"It's all speculative at this time of year. Alarazi has come out of the weekend fine and will go to Leopardstown for the 2,000 Guineas Trial.

"But our best prospects this year look to be among the fillies. If there's a Group One performer here, it could be a filly like Arch Swing or Hasanka," Oxx said. "The horses in general are quite forward. It's no problem getting horses fit these days on modern facilities. It's more a question of keeping them healthy."

Crooked Throw was runner-up to the eight-length winner Deauville Vision in Sunday's Irish Lincolnshire but Charlie Swan is preparing for a quick reappearance by the horse in Saturday's English version at Newcastle.

"He has come out of Sunday really well, eaten up and there isn't another race for him for six weeks," Swan said yesterday.

"He ran at the Curragh and if he had been beaten for or five lengths I'd have been sick as he clipped heels in the straight. Billy Lee will ride as he needs someone cool on him. He always misses the break and is real hold-up horse," the trainer added.

Crooked Throw is a general 16 to 1 shot for the Lincoln which is being run at Newcastle this year due to renovation work at Doncaster. In Bawaader's absence, it looks like Swan's horse will the sole Irish-trained runner.
