Aidan O'Brien's 28 Group One winners in 2017 as he breaks Bobby Frankel's world record of 25


Aidan O'Brien ended his record-breaking 2017 with 28 Group One winners, which broke Bobby Frankel's previous mark of 25 in a single season.

The trainer equalled Frankel's mark of 25 thanks to Hydrangea's victory in the Fillies & Mares at Qipco British Champions Day at Ascot and moved onto 26 when Saxon Warrior won a dramatic renewal of the Racing Post Trophy.

He struck gold with Mendelssohn in the Breeders' Cup Juvenile Turf while Highland Reel got the emotional 28th when bowing out before retiring to stud with victory in the Hong Kong Vase.

Here, we list all his Group One winners in 2017 with a selection of video clips while you can click on each race for the full result and full replay.
