Weighed In: the standout moments from the recent racing action

Performance of the week

It is impossible to look further than the main man Aidan O'Brien. His breaking of Bobby Frankel's Group and Grade 1 world record may have been inevitable for weeks but that should not detract from the magnitude of the achievement.

The majority of trainers would give everything to have 26 Group 1 winners in their entire career, never mind in less than 11 months, and the very fact it seemed inevitable is a remarkable testament to just how great he is.

Make no mistake, we are living through a period that racing historians will write about long after all of us are gone. The genius of O'Brien coupled with the dominance of the mighty Galileo is something to be savoured.

Ride of the week

Frankie Dettori is riding at the peak of his powers and he had Charlie Hills purring after he steered Nebo to victory in the Horris Hill Stakes at Newbury on Saturday. "I thought Frankie gave him a masterclass ride," said the trainer after Dettori had delighted the crowd with his signature flying dismount.

Most exciting prospect of the week

The early days of both the Flat and jumps seasons are full of the promise of what might be to come and Slate House had the feel of a horse whose name we could hear an awful lot more of in years to come.

The five-year-old made his debut for Colin Tizzard at Cheltenham on Friday, having been picked up for a hefty £260,000 in March and while the trainer was not getting carried away, he was not playing down expectations either.

It is a long way from winning a maiden hurdle to stardom but if the key ingredients are talent and an able handler, Slate House has much in his favour.

Quote of the week

"It was a bit of a worry putting my eldest son on horses that damaged two people, but it's all worked out"

Nigel Twiston-Davies reflects on his son Sam's winning rides aboard Cogry and Foxtail Hill at Cheltenham on Saturday. Cogry hospitalised Ryan Hatch at last year's November meeting before Foxtail Hill injured Twiston-Davies' other son Willy at the festival in March.

Disappointment of the week

It is hard to imagine any group of people felt more gutted this week than connections of Roaring Lion following the Racing Post Trophy at Doncaster.

Amid all the fanfare surrounding Aidan O'Brien's claiming of the world record was the undeniable fact the John Gosden-trained Qatar Racing colt threw it away.

He looked for all the world like winning after taking it up from Saxon Warrior and surely he would have had he run in a straight line. As it was, he hung left and the rest is history. It will be fascinating to see if Gosden can work his magic and train this tendency out of Roaring Lion.
