Double Guineas joy for O'Brien

Fresh from providing his son, Joseph, with his first Classic winner 24 hours earlier on Roderic O'Connor, the Ballydoyle handler also had a three-timer on the undercard at Irish Headquarters, with Australian import So You Think once again looking imperious in the Tattersalls Gold Cup.

Misty For Me was a leading juvenile filly but ran abysmally when well fancied for the Newmarket Guineas three weeks ago, meaning the three-year-old was available at double-figure prices in the morning.

Roderic O'Connor had put in a similar performance at Newmarket, however, and bounced back to win the 2,000 Guineas on Saturday, and plenty of punters had faith that the filly could repeat the dose.

Backed into 5-1, she was not spotted until late under Seamie Heffernan as it appeared that Together, ridden by Ryan Moore, was going to atone for her near-miss in the English equivalent. It was not to be for that game filly, as Misty For Me swooped wide and late to win going away by three-quarters of a length, suggesting she may even improve for a step up in trip. Jessica Harrington's Laughing Lashes flashed home third.

"She's always been a very good filly and she stays well," O'Brien said of the winner. "The plan for her was to come here and then on to Epsom for the Oaks. Together is likely to go for the Coronation now.

"Last year Misty For Me won on all grounds so I was puzzled by her run at Newmarket. It was hard to believe her run that day but she's bounced right back. I knew the ground wasn't the cause and it seems that she just didn't fire on the day.

"Seamie knows her very well from last year and gave her a great ride - she is a tough, hardy filly.

"The fact Roderic bounced back and won yesterday gave us hope. They were both very well going over and have been very well since so it may just be that they both needed their first runs.

"Together also ran ordinary on her first run of the season and ours always improve a good bit for a run."

Heffernan added: "I wasn't exactly confident going into the race until I saw Roderic O'Connor win yesterday.

"Aidan said to ride her positively and I'd won a Group One on her last year so I knew how good she was. We had a bad draw but good horses tend to get you out of trouble. It's emotional winning a Classic - there's only five a year."

O'Brien's So You Think made mincemeat of his Tattersalls Gold Cup rivals to tee up a crack at the Prince of Wales's Stakes. The giant Australian import dwarfed his rivals at the start, and the same was true as the race got under way as Ryan Moore cruised behind his pacemaker Windsor Palace until two furlongs from home.

Without much encouragement from the saddle the five-year-old pulled four and a half lengths clear of Godolphin's classy Campanologist, while Famous Name was well beaten in third.
