Ansgar gave Ireland a second consecutive victory in the OLBG Park Stakes at Doncaster.
Last year it was Eddie Lynam and Viztoria, and this time it was trainer Sabrina Harty who made a successful raid on Town Moor, and the 7-2 chance was given a cool front-running ride by James Doyle.
Better than ever at the age of six, Doyle had already partnered Ansgar for a recent Group Three success at Goodwood and they had just enough of an advantage by the line to thwart the charging 2-1 favourite Aljamaaheer by half a length.
Doyle said: "I was a little concerned at halfway as he must have changed his legs four or five times at that point and he's a horse that really needs to hear his feet rattle. But he's very, very tough.
"I could hear them all coming, but Sabrina and the team have done a great job with him. Pat Smullen also gave me some good advice about the horse."
Harty said: "It's a lucky place for us. We were delighted with Kalann yesterday (third in the Doncaster Cup) and this fellow is the real deal over seven furlongs.
"James said he would have won easier had the ground been quicker. He has a massive stride on him.
"There was nothing on Irish Champions Weekend for him except over a mile and he's better over seven.
"We'll just have to keep finding seven-furlong races for him and on good ground."
