As another Sydney trainers’ title beckons, Chris Waller is already looking for his next edge.

The fourth running of the world’s richest race, the US$20m Saudi Cup (G1) went the way of Japan for the first-time when Panthalassa lead throughout to win and complete another memorable Saudi Cup Meeting for the Japanese raiders by completing a treble and for trainer Yoshito Yahagi a double.

Frankie Dettori and Country Grammer just missed out as Panthalassa produced a remarkable front-running performance to strike gold for Japan in the $20million Saudi Cup.

Frankie Dettori has already won one of the world’s most valuable races on Bob Baffert’s Country Grammer and he now has his sights set on another in the Saudi Cup.

Friday and Saturday, King Abdulaziz racecourse in Riyadh, Saudi Arabia will play host to the world’s richest horserace, the Saudi Cup (G1) worth US$20m. The race is the feature on a sixteen-race two-day fixture with prizemoney totalling US$35.5m.
