Thunder Rock provided Sean Bowen with his biggest success since returning from injury in the Listed bet365 Premier Chase at Kelso.
Bowen - who has seen his lead at the top of the jockeys' championship eroded and then passed by Harry Cobden - has struggled for winners since his return to action but victory on one of Olly Murphy's stable stars will have done him the world of good.
Given a patient ride, Thunder Rock grew in confidence as the race progressed, as Minella Drama, Aye Right and Elvis Mail tried to stretch things.

Grand National fancy Monbeg Genius struggled to get on terms and when Thunder Rock went cruising on by as they turned into the straight, it was clear he had no more to give.
Thunder Rock found plenty in the home straight and the heavily-backed 9-4 favourite came home seven lengths clear of Minella Drama, booking himself a ticket to Aintree and a step back up in class.
Bowen said: "He proved he stays three miles. They went quick and every time I gave him a squeeze he picked up.
"I was confident where I was and Olly gave me a lot of confidence going out to ride him. I'd been riding a lot more seconds than winners since I came back and I was getting a bit frustrated. It always helps having a good boss like that."
Murphy said: "I really enjoyed that. I went to Cheltenham in December when I felt like I'd set him up for a big handicap but he may as well have pulled up and it's been an upward curve since then.
"He ran well the last day at Musselburgh on the wrong track when he was wheel-spinning for two and a half miles but it did his confidence good.
"I said to Sean not to get in a battle with him and ride him with confidence because he was the classiest horse in the race and to make that tell and he did just that.
"It's been hard for Sean, he's riding through pain and we've had a quiet couple of weeks ourselves so this will do him the world of good."
He added: "I think we'll go to Aintree with him for the Bowl now, it's a Grade One so he'll need to step up again but a small field suits him and he'll be back over 150 in a handicap again."
