No Diamond for Siren

Sea Siren could not make a winning European debut at Royal Ascot when finishing eighth in the Group 1 Diamond Jubilee Stakes (1200m) overnight but the mare could yet be seen in action again after making a notable change of stables.

Prepared in Sydney throughout her career by John O’Shea, the daughter of Fastnet Rock was purchased by Coolmore prior to her second-placed finish in the Doomben 10,000 and will be transferred to their principal Irish trainer Aidan O’Brien in County Tipperary.

Sea Siren, who won last year’s Group 1 Sportingbet Manikato Stakes (1200m) at Moonee Valley, showed up well for Ryan Moore in behind the eventual winner Lethal Force for much of the 1200-metre Group 1 but weakened in the final 200.

O’Shea believed the long journey from Brisbane as well as busy campaign had taken its toll.

“She got a bit tired up the run-in,” he said. “It’s a learning experience as she is probably saying she has had enough – she had a hard run in Brisbane and then the trip up here.

“I think it’s a doable thing if you get your horse to the right stage of its preparation. It would be wonderful to win here – we’ve just got to find five or six lengths.

She is going to Aidan on Monday night so I just had a chat with him to help him get a feel for her.”

Moore said: “I think the stiff track found her out. She jumped out well just outside the leader but then just struggled up the hill.”

Sea Siren is not eligible for next month’s Darley July Cup, and O’Brien was asked about possibilities for her next race.

He said: “Obviously the lads (owners John Magnier, Michael Tabor and Derrick Smith) will talk about that.”

Lethal Force is one of two smart sprinters in the care of Clive Cox, who also has dual juvenile Group 1 winner and day one King’s Stand Stakes (1000m) fifth Reckless Abandon in his Lambourn stable.

Providing a first success at this level for Adam Kirby, the grey charged out of the gates and never looked like being headed, crossing the line two lengths clear of the 2011 hero and favourite Society Rock.

He was beaten a head by Society Rock on worse terms at the weights on their matchup in last month’s Group 2 Duke Of York Stakes.

“Lethal Force was having a blow in front and when Adam sent him on he was explosive – it was a very authoritative victory,” said Cox.

“He’s clearly very good at this trip so we’ll see how he is and plan the rest of the season from there.

“He’s in the July Cup but I’m not sure if Newmarket will be his track – although it does look logical. Reckless Abandon is in it as well, but we won’t worry about that now.

Society Rock and third-placed Krypton Factor also head for the July Cup, the next and final British leg of the Global Sprint Challenge.

Lethal Force is now eligible to collect the VRC’s $600,000 bonus for any horse that can win the Group 1 Patinack Farm Classic (1200m) after claiming an international leg of the Global Sprint Challenge should connections ponder a trip to Melbourne.
