The TAB.com.au's markets saw some instant movers, with pacing series favourite Tiger Tara snapped in from $3.20 to $2.60 by punters, after a tantalising front row draw outside polemarker My Alpha Rock and front runner Wrappers Delight.

There was misfortune for Victoria's two most likely with Shadow Sax and San Carlo both drawing off the back row in heat two, whileAll Stars' entrant Cruz Bromac shortened from $1.55 to $1.35 in the final heat amid expectations he could find the front and win from gate four.

Speeding Spur has a dominant grasp on the first of the trotting heats, opening at $1.35 with the TAB after the top rated Kiwi drew gate two, while rival Tornado Valley was listed a $1.50 pop from gate six in the other heat.
