The flashy chestnut is a beautifully bred son of New Approach, owned and bred by Normandie Stud.
A naturally forward-going colt, Pretzel was always handy under Andrea Atzeni, racing close to the leaders.
He showed a good turn of foot to hit the front going into the 'Dip before staying on well to win by a length and a half.
Roger said: "He is a nice colt. He carries himself in a lovely way and moves beautifully. It's good to know that he handles this ground but I don't think faster ground will be a problem for him.
"He probably won't run again this season."
