Winx stamped her place in racing history with an authoritative and unprecedented fourth success in the Group One Ladbrokes Cox Plate at Moonee Valley.

Winx was bidding to win 29 straight races and become the first horse to win the race on four occasions.

Seven horses faced the wonder mare, in this 1 ¼ mile contest.

At the break, it was the grey D’Argento who went into the lead, with Benbatl for company as they headed into the first bend.

D’Argento held a narrow lead going into the back, with Rostropovich and Benbatl close up, while Kings Will Dream was sadly pulled up.

Rostropovich came to join D’Argento with half a mile to race and Ryan Moore, racing wide, went on, with Benbatl stalking these all the time.

Approaching the home turn, Winx moved up on the outside.

Into the straight, Winx and Hugh Bowman had edged into a narrow lead, with Benbatl challenging to the inside.

As they straightened up, it looked for a split second as though there might be a battle.

But Winx was irresistible and moved on to win by a couple of lengths, to tumultuous acclaim from the stands.

Benbatl was in the perfect position, but was no match for the mare, while Humidor stayed on for third, clear of Avilius.

Bowman said: “I’m just so proud of the horse. I can’t believe it, I really thought in the build up to this that I’d get quite emotional. I am feeling emotional but the electricity that came through my body turning into the home straight just then was something I didn’t just get to feel but hopefully everybody else watching.

“I’m lost for words. Everybody watching her gets so much pleasure from her, out of her superb ability. The fact she’s been able to do so many times consecutively just speaks volumes of the management of her.”
