ZENITH ROCKET (3) missed the frame but ran a sharp fifth at this track over 480m in 28.80. Rates a top chance again if runs up to latest. VAMPIRE BOB (5) won by half a length last start when getting around this track 480m in a dynamic 28.67. Has the ability and can measure up again. SON OF THOR (4) comes off a moderate effort last start, finishing fourth at this track over 480m behind Bogger Bob (28.98). Should play a prominent role. GOLDSTAR MICHAEL (1) is last start winner who looks one of the chances.
