12Follows: Darren Potter's Flemington black bookers

MELBOURNE form epert Darren Potter names his horses to follow from Saturday's meeting at Flemington.

Astro Castro: We've said plenty about unseen horses on the show before but we found out on Saturday just how much this bloke has to offer. He won the fastest race of the day on debut which was a phenomenal effort. Will be interesting to see how the market treats him going forward.

Kinshachi: Ran third to Stylemaker but would’ve won comfortably had Craig Williams rolled forward. She's been in the money all three runs this prep and can return to the winners' stall next time out in a suitable race.
