AIDAN O'Brien has broken the world record for the number of Group 1 winners trained in a season.

Hydrangea's victory in the Group 1 Qipco British Champions Fillies & Mares Stakes at Ascot last week was number 25, equalling the tally set by the late great Bobby Frankel.

The one to break the record is leading Derby prospect Saxon Warrior who, though looking like he would have to settle for second when Roaring Lion edged past him in the final furlong, fought back on the rail to take the Group 1 Racing Post Trophy at Doncaster by a neck.

Stable companion The Pentagon finished two and a half lengths farther back in third, with the Jim Bolger-trained Verbal Dexterity another three-parts of a length away in fourth.

The Deep Impact colt made a huge impression on his racecourse debut at the Curragh and, having followed up in last month's Group 2 Beresford Stakes at Naas, he was the 13/8 favourite to provide his trainer with an eighth triumph in this juvenile event.

DELIGHTED

O'Brien surpassed the record for number of top-level wins in a calendar year set by American trainer Bobby Frankel in 2003.

He told ITV Racing: "I'm delighted and delighted for everybody. There's a lot of hard work put in by a lot of people in Ballydoyle and Coolmore.

"It's unbelievable really. There are so many people who put in so much hard work day in, day out. If I start mentioning people, I'd forget somebody. They know who they are.

"It's a privilege to be working with such special people. We're in a very lucky position and we're a small link in a big chain."

Of Saxon Warrior, the trainer added: "He travelled very strong and Ryan gave him a brilliant ride.

"When John's horse went by him you thought he was beaten, but he found plenty and we're delighted."
