Buick and Appleby rule again in English 2000 Guineas
Norway-born Buick puffed out his cheeks after crossing the line as he had opted to ride 9/2 chance Ruling Court ahead of Appleby's other runner Shadow of Light.
Three years ago he had made the wrong choice choosing Native Trail, but it was Coroebus who won.
Ruling Court had just enough to hold on from the fast finishing 15/8 favourite Field of Gold -- Shadow of Light (6/1) finished third.
"It feels great," said Buick.
"He was so smooth throughout the race. His stamina shone through.
"He is a very special and intelligent horse and for sure he can go on to the Derby," added the 36-year-old.
The bookmakers were impressed enough to shorten his odds to add the Derby -- which is half a mile longer -- from 12/1 to 9/2.
Appleby has become accustomed to visiting the 2000 Guineas winners enclosure in recent years, this the third victory for him in the last four editions.
"I got there in the end took a few years to get hang of it (the 2000 Guineas)," joked 49-year-old Appleby.
"Came here with a lot of confidence, it was a hard choice for William but he made the right one.
"He outstayed them, William got a nice clear run out of him...it was a great ride.
"We will let the dust settle about his future campaign even if he is the only horse we have entered in the Derby."
Field of Gold's run left John Gosden -- who co-trains with son Thady -- frustrated as it remains the one British classic to have eluded him in 36 years.
The 74-year-old appeared to criticise jockey Kieran Shoemark for being caught cold by Buick being in a better position to strike.
"William got first run on him, he finished strong but we ran out of track," he said.
"That's racing probably needed to be a bit handier."
Appleby and Buick can round off the weekend in style as Desert Flower is favourite to deliver them their first 1000 Guineas on Sunday.
