Star Lahib edged out Tepmokea as the front-runners dominated the finish of the bet365 Old Newton Cup at Haydock.
A field of 17 faced the starter for the prestigious Heritage Handicap but very few of them got involved in the near mile and a half contest as Franny Norton edged out Jim Crowley aboard the Mark Johnston-trained winner.
Both the first and second were always to the fore - along with Fennell Bay and Scatter Dice from Johnston's yard - and they pulled clear of the chasing pack inside the final furlong.
Opinion flashed home late in the day having been held-up towards the rear but finished outside the frame with Fennell Bay holding on for third from Highland Castle whose effort flattened out a little having raced a shade keenly early on.
"She was in the sales, but she started to come good a while back so the owners took her out. Thank goodness they did," said Johnston.
"This filly has been taken out of a couple of races because the ground was too firm for her. I was very tempted to pull her out this time to let Party Line in, but she supposedly wants cut in the ground so I left this one in because it's a £100,000 race.
"If it had been a £10,000 race I would have taken her out. I did also have doubts about the trip. I thought a mile and a quarter with cut in the ground was for her.
"We'll try to find more races of the same and make hay while the sun shines."
Winning jockey Franny Norton picked up a two-day ban (July 20 and 21) for using his whip above the permitted level.
