Super Seth has produced a potent finish for a last-stride win in the $2 million Caulfield Guineas.

Giving jockey Mark Zahra consecutive Group One wins at Caulfield, Super Seth overhauled Alligator Blood on the post to claim the $2 million race.

Alligator Blood seemed set for victory when he shot away at the 300m but he weakened late with the winner’s stablemate Groundswell finishing in third minor placing.
