It Came To Pass was a surprise 66/1 winner of the £45,000 St James's Place Foxhunter Chase for father and daughter Eugene and Maxine O'Sullivan.
The 10-year-old always travelled strongly and produced a fine leap at the final fence before careering away up the Cheltenham hill to record a facile 10-length success over 11/4 favourite Billaway.
The winner trainer Eugene O'Sullivan also saddled Lovely Citizen to success in the Foxhunter back in 1991 which was ridden by his brother Willie O'Sullivan.
Maxine O'Sullivan has been crowned the leading female point-to-point rider on four occasions in her native Ireland and was delighted to record a first success at The Festival™ presented by Magners.
She said: "This doesn't happen to us. This is our Gold Cup and it just means so much. For my family and the lovely owners of It Came To Pass, it's just such a big family thing. A lot of effort went into getting here and it is just so good. I will remember this day forever.
"My uncle won the race on Lovely Citizen in 1991 which dad trained and my grandad [Owen O'Sullivan] owned and bred it. Unfortunately, he died in the last couple of years, but he would be so proud.
"It's a really special race for us and it's just brilliant. I'm really happy and it's just such a family business. Even the community and all the lads at home, it will mean a lot for us.
"This is off the scale. I have only ridden in this race once and I dreamt of winning of this, but I didn't think it would - this is really good. This is just amazing. Everything went our way today.
"It Came To Pass does not particularly like being crowded and he didn't particularly like the track, but we were able to keep wide and get our bearings. He just loved it the whole way and everything went right. I couldn't have asked for a better run around.
"His last two runs were poor, but we were confident we had an excuse for that. He was a bit unwell and we got him right - he had been in great form all week.
"We knew if It Came To Pass returned to his old form, which was at the start of the season, then he had a serious chance and today he was better than he had ever been.
"He usually doesn't travel very well, but he travelled super the whole way. He stays very well. I just wanted to hold onto him for as long as possible. I knew he would come up the hill and it was great that it worked out for me. He jumped brilliantly at the last two fences and I had a small look at the screen so I knew he was OK."
Mullins eyes up trophy for next year with runner-up Billaway
Team Mullins, jockey Patrick and trainer Wilie, were sanguine of their second place from 11/4 favourite Billaway, who came home 10 lengths adrift of the winner, 66/1 chance It Came To Pass, in the St James's Place Foxhunter Challenge Cup Hunters' Chase for amateur riders.
Wilie Mullins, commented: "We came here hoping he could do this, but we have a bit more work do.
"My owner [Mr J Turner] has just seen the trophy for the St James's Place Foxhunter Hunters Chase, which is the most magnificent trophy of all week. He has gone up to measure it so he can order his new sideboard for the trophy next year.
"We will bring this horse back. Hopefully he might have a little more experience next year. We will hope to go one better next year.
"I think he could improve with experience and improve with his jumping."
Jockey, Patrick Mullins, added: "It went very well. Everything went to plan. He settled well and jumped fine on the whole. We just ran into one on the day. He [It Came To Pass] beat us last year at Cork in April. I really looking forward to coming back next year with him."
Loxton happy with third-placed Shantou Flyer
After Shantou Flyer finished third under owner/rider David Maxwell, trainer Rose Loxton to her previous runners in the race when saying: "We're getting closer. We've been fifth and fourth and now third. He ran a blinder and David said he was amazing and galloped all the way to the line, but was beaten by two better horses on the day.
"He would have preferred it if it had rained all week - he probably found that ground a bit holding - but he jumped amazingly and tried his heart out."
Loxton said Shantou Flyer could run at Cheltenham's evening hunters' chase meeting in May, while her other runner in today's race, Caid Du Berlais, did not enjoy the experience. He is set to return to Punchestown where he has won the Champion Hunters' Chase for the past two years.
