Five of the first 10 horses in Golden Slipper betting go head-to-head at Randwick.

Straight Charge has beaten barn mate Espionage to give Gai Waterhouse and Adrian Bott another Silver Slipper.

Farnan is the last horse to win the Silver Slipper-Golden Slipper double and his former trainers have two colts vying to emulate his feat.

Tulloch Lodge colt Espionage is set for his first public appearance since the spring.

The Silver Shadow Stakes will be an important litmus test for five Randwick-trained stablemates.
