Librannoâ€™s unbeaten record has been preserved with an all the way victory in the TNT July Stakes.
Godolphinâ€™s Neebras gave him the most to worry about, but he badly missed the break and with his endeavor waning, he finished his run back by three quarters of a length.
Elzaam was an unsatisfactory third with Norfolk victor Approve in fourth place.
"He's a very tough horse and he saw it out very well," said Moore.
"Richard (Hannon) is cleaning up in this division."
Hannon, who has done extremely well in the two-year-old division, said, "I ran him half-cooked first time at Newmarket and normally if ours come on and win first time there's a bit more in the tank.
"I just told Ryan not to organise him and that they would all come looking for him, but not to worry about it.
"Obviously Strong Suit is a very, very good horse, but so is this fellow as he's won both his races."
Mahmood Al Zarooni, trainer of the second place getter, said, "I'm very happy with the run and the winner is a nice horse.
"Frankie (Dettori) said he's a horse without a lot of experience and if he had more experience he would have run even better."
Michael Jarvis said of Elzaam, "He's run disappointingly."
Owner of the winner,Ollie McDowell added, "We were favourite for the Racing Post Trophy about 10 years ago with a horse called Scarteen Fox and my sons feel we've got unfinished business in the race, so we'd like to end up at Doncaster but the rest is up to Richard."
Sky Bet has given Libranno a first show quote of 20/1 for next year's 2000 Guineas.
Matt Doyle said: "The winner is now unbeaten in two starts and going the right way, but odds-on favourite Elzaam didn't show up today after his cracking run in the Coventry.â€
