Slade Power could return to Haydock for the Betfred Sprint Cup after winning the Blue Square Listed Sandy Lane Stakes.
The lightly-raced three-year-old was giving Irish trainer Edward Lynam compensation for Sole Power having to settle for second in the Temple Stakes at the Merseyside track a week earlier.
Slade Power (5-1) lunged late in the hands of Wayne Lordan to deny the front-running Es Que Love by a neck and make it three wins from five starts.
"He's a horse to keep an eye on. He's a big raw horse and could be one for next year," said Lynam.
"I might bring him back here for the Sprint Cup in September, but I want to look after him this year.
"He's only been beaten by two horses of Aidan's (O'Brien), Ishvana and Reply, and they were placed in the 1000 and 2000 Guineas at the Curragh last week.
"He looks like a seven-furlong horse but the jockeys say six is his trip and he travels so well."
Pastoral Player (3-1) has Black Caviar in his sights over six furlongs after opening his Pattern-race account in the Timeform Jury Stakes.
The son of 2005 July Cup hero Pastoral Pursuits could take on the Australian super mare in the Diamond Jubilee Stakes at Royal Ascot after graduating from handicaps.
Majestic Myles looked like lifting this seven-furlong Group Three when he headed the pace-setting Red Jazz, but he had no answer to Hughie Morrison's five-year-old.
Pastoral Player showed a tidy turn of foot under Darryll Holland to win by a length and a half.
"This is important for his sire," said Glen Swire, of owners the Pursuits Partnership.
"The penny has taken a long time to drop with this one. He was a very wild boy.
"The question is where we go next. How many is Black Caviar going to frighten off?
"He was third in the Wokingham last year, he likes the track, so maybe we'll go for the big one."
Set To Music narrowly failed to give the Queen further cause for celebration during Diamond Jubilee weekend when she was narrowly beaten in the Grosvenor Casinos Pinnacle Stakes.
Michael Bell's filly could not quite get to Shimmering Surf (9-1), who held off all-comers in the closing stages.
Always in the front rank under Neil Callan, the Roger Varian-trained filly held Set To Music by three-quarters of a length.
"I've only had her this year but she ran very well at Goodwood on very different ground to here," said Varian, who inherited the winner when her owner Peter Winkworth retired from training.
"It was soft there, but I felt she was in similar form coming here and had been working well.
"I hoped she'd run well but on this quicker ground and a strong field we thought she might find one or two too good for her, so we're delighted.
"She might come back here for the Lancashire Oaks. With this Group (Three) win under her belt we can have some enjoyment out of her."
Inetrobil (20-1) gave owners Highclere Thoroughbred Racing a little consolation for Bonfire's defeat in the Investec Derby when battling to victory in the EBF Play Poker With Grosvenor Casinos Stakes.
Wearing blinkers for the first time, Kevin Ryan's filly got home by a neck from Artistic Jewel under Phillip Makin.
The jockey said: "She's laid-back so the blinkers were the key and she's not had her ground for a while.
"She's got a great action and needs decent ground. She was tough to put her head down and get stuck in."
Lordofthehouse (5-1) quickly recovered from a slow start to get to the front and gallop to an emphatic victory in the Bet At bluesquare.com Handicap.
The William Haggas-trained four-year-old kept pulling out more for Chris Catlin and went on to beat Dazinski by two and a half lengths with Palazzo Bianco a further length and a quarter away in third.
Catlin said: "He's still learning and he's going to progress as he gets older.
"There's more to come and he could end up being a nice staying horse."
Apprentice Natasha Eaton followed up her win on St Ignatius at the track on Friday evening when making all on the Alan Bailey-trained Fleeting Image (14-1) in the Blue Square Maiden Stakes.
Harry Bentley enjoyed a smooth success on the William Knight-trained Safari Sunseeker (9-1) in the Grosvenor G Casino Handicap.
The favourite Red Quartet stayed on late but was two lengths down at the line.
