The Racingpost's analysis:
Seldom since Entrepreneur went off at 4-6 in 1997 has the Derby build-up been dominated to such an extent by one horse, or perhaps more pertinently one rider. However, while Authorized had looked different class when following up last year's Racing Post Trophy win so impressively in the Dante, and offered Frankie Dettori his best opportunity yet, this Derby looked no less intriguing an affair than any before it, with an eight-strong battalion from Ballydoyle potentially adding a massive additional tactical dimension to a race in which there were all the usual stamina, temperament and going questions to be answered.
Teofilo's continued absence robbed the race of last year's outstanding juvenile, and Classic form was thin on the ground, with only three unplaced runners from the 2,000 Guineas to represent it, but it featured the winners of all of the main trials, plus unexposed runners with the scope still to improve significantly over the longer distance.
The drying ground meant that the going would not be much of an excuse for any beaten runners, and a race run at a strong pace throughout passed with remarkably little incident and no hint of team tactics.
As at York, AUTHORIZED was simply different class, and the manner in which he stormed clear inside the final two furlongs to win by a margin that has not been bettered since Slip Anchor won in 1985, suggests he must be right up there with the best recent winners of the race.
A little warm behind the saddle initially but otherwise in tremendous shape again, he soon settled down and, by the time they arrived at the start, there were many others who looked much hotter.
One of the slowest away, he was much further back through the first furlong then one would have wanted him to be, but Dettori did not rush him into contention and instead rode him with no end of confidence. Still only ninth approaching the straight, but with all those behind him in trouble and the leaders in his sights, he cruised up on the outside to join issue around two furlongs out and then quickened right away when asked to go and win his race. He was given a couple of smacks to make sure, but it really wasn't necessary for he strode away imperiously to win with overwhelming authority. He equalled the winning margin ofsuch outstanding colts as Nashwan, Generous and Motivator in a time that could not have been even contemplated when soft ground was on the cards earlier in the week, for it was quicker than the 2005 and 2006 time and more than a second under the Racing Post's standard.
He looks far and away the best middle-distance three-year-old around and will be very hard to beat. A drop back in trip for the Coral-Eclipse will not trouble him, and one could see him going through the season unbeaten.
The 2,000 Guineas fifth Eagle Mountain beat the rest by a clear margin and did remarkably well to finish where he did, having had only a couple behind him into the straight, connections reporting he had been interfered with a little earlier on. He made up a deal of ground in the straight, following a similar path to Authorized, but the winner had long gone. He will now be aimed at the Irish Derby, and if Authorized is absent he will take plenty of beating.
Aqaleem didn't have anything like the form claims of the stable's 2006 winner Sir Percy, for the Lingfield trial did not take a lot of winning, but he had been impressive there and carried a fair measure of stable optimism. He got warm in the parade ring, but proceeded to run a blinder in third, soon in a good position from what connections saw as a tricky draw and sticking on gamely. He looks obvious St Leger material.
Lucarno made his racecourse debut less than two months ago, but he was tremendously impressive in a small field at Newmarket lastweek and justified the bold decision to run him again so quickly with a cracking effort in fourth. Another who was in the leading group throughout, he went into second behind Kid Mambo just before Authorized arrived on the scene and missed third by only a head. He has had four quick races now, but connections are thinking about races like the King Edward VII or the Grand Prix de Paris, and he surely has a major race in him at some stage.
Soldier Of Fortune looked a stayer in the Chester Vase, and although he ran really well here, he just lacked a bit of pace. He could be a St Leger type too, but would be worth his chance in the Irish Derby first.
Salford Mill's trainer had misgivings about the ground, but it dried out so much that it cannot have inconvenienced him too much. He didn't go well through the first half of the race and was still among the backmarkers straightening for home, but he picked up well approaching the two-furlong marker and kept on to the line. He looks a likely type for the King Edward VII.
Kid Mambo, placed behind the Oaks winner Light Shift at Newbury and behind Aqaleem at Lingfield, had a lot more use made of him here and set a really good pace. It was only inside the last two furlongs that he was eventually headed, and connections concluded that he did not stay. He will drop back to around 1m2f now.
The Derrinstown second Yellowstone ran much better than his stablemate Archipenko, who beat him there, but once again he looked a stayer.
There were stamina doubts about Archipenko, but he was beaten long before that became an issue and Michael Kinane reported he had lost his action coming down the hill.
The inexperienced Acapulco, another from the O'Brien camp, was driven into third as they straightened up, and although he couldn't hold his position, he was far from disgraced. He was clear of a much shorter-priced stablemate, the Royal Lodge and Dee Stakes winner Admiralofthefleet, who probably didn't stay.
There was quite a gap back to Mahler, another from the stable and a progressive type. He had been a live outsider in the morning but was in trouble rounding Tattenham Corner.
Anton Chekov chased the leader until into the straight but droppedright out. The ground would have been plenty quick enough for him.
The Sandown winner Regime looked in great shape and appeared to be first-six material at least, but Martin Dwyer felt he might have tweaked a muscle early on as he was never reallygoing.
Rank-outsider Leander started slowly and was always well back. Fellow 100-1 chance Petara Bay, who had far better form and had beaten Salford Mill at Newmarket, was never travelling and connections were baffled by his performance. They think the world of him and an excuse had emerged for his Sandown defeat, but this was very disappointing.
Connections of classy juvenile Strategic Prince expressed major misgivings about the ground, but while it wasn't as quick as they would have liked, that in itself cannot explain his performance here. Failing stamina was as big a factor and he beat only Archipenko. (GD)
