High Definition is the new favourite for next year's Derby after he provided Aidan O'Brien with a 10th successive win in the Alan Smurfit Memorial Beresford Stakes at the Curragh.

Having flown home late to get up on his debut, High Definition was sent off the 9-5 favourite, but he had only one behind him with three furlongs to run and Seamie Heffernan was already rowing away as Monaasib kicked clear.

Heading into the final furlong, Kevin Prendergast's Monaasib appeared a likely winner, but High Definition really began to grab the ground close home and he ended up winning by a cosy three-quarters of a length.

High Definition, who is a full brother to last year's race winner Innisfree, is now the market leader for the 2021 Epsom Classic.

O'Brien, who was winning his 20th Beresford Stakes overall, said: "He's lovely and puts away a lot of ground.

He's a big, rangy horse with a massive, big stride and is one to really look forward to.

"It was the same in his maiden - you would say he's not going to get there and in the end he's won easily.

"I'd say we'll put him away now. He could start in a Guineas and he looks like he'll be a middle-distance horse.

"I was a bit worried about the bend as he's never been around one before."

O'Brien had earlier been on the mark with Santa Barbara (9-2) in the Irish EBF Median Sires Series Maiden.

A half-sister to Group One winner Iridessa, Santa Barbara travelled well throughout in the mile heat and eventually came home an easy two-and-a-half-length winner.

O'Brien said: "She's a big, powerful filly with loads of class. She was just ready to go racing. She travelled very well through the race.

"There is a good chance she won't run again this year. We just needed to get a run into her and she's going to be lovely for next year." 

Meanwhile, Derby hero Serpentine could yet be added to O'Brien's team for the Prix de l'Arc de Triomphe at ParisLongchamp.

The Ballydoyle handler already boasts the big-race favourite in dual Classic winner Love, but he still may supplement the shock Epsom victor for the 12-furlong showpiece on Sunday week.
Serpentine has only run once since his Derby success, finishing fourth behind stablemate Mogul in the Grand Prix de Paris over the Arc course and distance earlier this month.
Mogul is also in contention for Arc honours, but the Coolmore team could stump up 72,000 euros on Wednesday to add Serpentine to a possible five-strong team in Paris.
O'Brien said: "There is a good chance that Serpentine will be supplemented. He seems to have come out of his race well.
"We also have Mogul, Japan, Love and Sovereign."
