The Flying Mile has been extremely kind to leaders over a long period of time, horses who have been able to lead and control the race. Star Galleria did just that to beat Heaven Rocks two years ago and Pembrook Benny did the same to down Christen Me.
With his gate speed Mach Shard should be first of the favourites to the markers tonight and as good as Thefixer and Chase Auckland are, they are not as scary as their stablemates like Ultimate Sniper and Self Assured.
So while Purdon wouldn't come out and declare it, he is confident Mach Shard can stand up to be counted.
"The final driving tactics will be up to Zac but he did, after all, work early and still run a close second in the Inter Dominion Final. So he would definitely be hard to beat in front."
If Mach Shard does lead as expected he would easily pace a 1:52.5 mile on peak performance should tonight provide good conditions and that would mean horses coming wider on the track, as the favourites may have to do, will need to be good to beat him.
Thefixer and even Chase Auckland may simply still be a length better than Mach Shard and either one sitting in the one-one, if Mach Shard leads, might grab him. But the history of tonight's race suggests Mach Shard is a great each way bet.
While leading might be enough to give Mach Shard a huge chance in the pacing feature, it might not be enough for Oscar Bonavena's rivals to down him in tonight's $30,000 Trotting Mile.
He was beaten in the National Trot at Alexandra Park last start when forced to sit parked, an expensive reminder that as talented as he is this is his first summer in the big time.
Rivals likes Tickle Me Pink and Massive Metro may fancy their chances of staying in front of Oscar Bonavena and stablemate Winterfell tonight but Oscar may still be too sharp if he can get handy.
Still, punters might struggle to take the $1.30 fixed odds about him as the one-one might be his only economical path to victory.
Winterfell is a hard one for punters to assess as he has to be rated our best trotter on performances in the last month but there are usually question marks about him left-handed and if he wins tonight he may have to do it the hard way.
Still, he keeps rising to the challenge and another victory tonight would take him even closer to the Trotter of the Year title.
Meanwhile, former Dominion winner Marcoola has returned to Canterbury and trainer Ken Ford after his rollercoaster short stay with Barry Purdon over the Inter Dominions.
And the Purdon pair of Bad To The Bone (Vic Derby) and Belle Of Montana (Ladyship Mile) are on target for Victorian campaigns in coming weeks.
Mile Night picks
• Best bet: She Reigns (R7, No.8): Has high gate speed and raced in far stronger field last start. Can get handy or even lead so draw not as bad as it looks.
• Each way: Mach Shard (R6, No.3): Looks the leader and it will take a good horse to beat him. Only danger might be whoever sits in the one-one.
• Class drop: Ideal Agent (R3, No.8): Solid sixth in Sales Series Pace last start and huge drop in class. Outside barrier aided by two scratchings inside on front line.
