ASCOT, England (AP) -Co-favorite Starspangledbanner won the Golden Jubilee Stakes on the final day of racing at Royal Ascot on Saturday.

In an international field, Australia's Starspangledbanner dominated the race, coming in ahead of Society Rock, followed by Kinsale King.

It was the third winner in two days for trainer Aidan O'Brien and jockey Johnny Murtagh, after Lillie Langtry won the Coronation Stakes and Mikhail Glinka took the Queen's Vase on Friday.

``It is incredible that he was able to win over a mile in Australia and he came over with a massive reputation, we were very lucky to get him,'' O'Brien said. ``He's the fastest we've had, no doubt. We've never had one go that fast furlong by furlong.''

Ascot success runs in the family for Starspangledbanner, an offspring of 2003 Golden Jubilee winner Choisir.

``He's very similar to his sire Choisir, big and strong,'' Murtagh said. ``Everything just worked perfect. He jumped well, traveled really well, a good strong gallop all the way.''

Murtagh won again later in the Wokingham Stakes on the five-year-old Laddies Poker Two.

Murtagh narrowly missed out on the week's top jockey award, which went to Ryan Moore. Moore rode Bergo, trained by his father Gary, to victory in the closing Queen Alexandra Stakes. Aajel was second and Swingkeel third.

``It doesn't mean a lot to me personally, but I am delighted to ride a winner for my dad,'' said Moore of his Queen Alexandra Stakes win. ``This is the biggest week in racing and it is very competitive and hard to win.''

He also rode the Michael Stoute-trained Harbinger to victory in the Hardwicke Stakes where Duncan and Barshiba were second and third.

In a busy day for Moore, the rider managed to finish second on Imposing in the Duke of Edinburgh Stakes, behind Cill Rialaig. Imposing recovered from a poor start to push the Hugh Morrison-trained horse all the way to the line. Martyr finished third.

Moore had a quiet start to the week, with disappointing runs on Rip Van Winkle, Steinbeck and Fencing Master, and Richard Hughes and Frankie Dettori appeared better placed to take the top jockey award for much of Royal Ascot.

But with Murtagh also having a successful closing day and competing in the final race on Deutschland, the award wasn't decided until Bergo crossed the line first. Deutschland finished 11th.

In the day's other race, Zaidan took the Chesham Stakes, three lengths ahead of Sonning Rose, followed by Casper's Touch.
