Saleh Al Homaizi and Imad Al Sagar's gelding was unlucky not to win over course and distance earlier this month and he had been training well at home since.
The leaders went off at a brisk pace and jockey Adam Kirby soon settled Agerzam into a good rhythm. He travelled strongly before bursting through to hit the front with two furlongs ago.
Agerzam pricked his ears and idled when clear but victory wasn't in doubt and he went on to score by a length.
Roger said: "Agerzam is a useful sprinter and deserved to get his head in front again. Everything went right for him today and hopefully this will do his confidence some good."
