Native Ruler In Control Of Winter Stakes

Native Ruler, tenth in ordinal rank in Durban July betting at odds of 20/1 on Interbet, did his prospects no harm when sauntering to victory in the G3 2400m Winter Stakes at Greyville on Saturday.

In a jog-sprint scenario, he proved much the best with Imilenzeyokuduma staying on into second without ever looking a threat to the Justin Snaith trained, Vercingetorix, 4YO.

Native Ruler was the fastest finisher in last year’s July (also a false run affair) and has plenty of ability. Harnessing that talent is not proving straight forward, however. He moved up to pacemaker Shoot the Rapids under a tight hold, then hung markedly down the straight, something he has done before, and is usually a sign of an underlying physical issue.

Trainer, Corne Spies doesn’t hold back when he has a powerful, robust young sprinter in his care. African Pride s/s 103 won a Pinnacle Stakes at Turffontein six days ago and was immediately trucked down to the coast for another stab at victory, with Mickaela Michel. They raced handy all the way, narrowly staving off the late dart of heavily backed, Position of Power s/s 102 in a Class 2.

African Pride is by former G1 winning Computaform Sprint hero, Rafeef. He’s won four of 12 starts by carrying his speed well, which makes him a hard horse to pass.

Circumbendibus (s/s 101, a career top) and the consistent, Vihaan’s Web s/s 101 followed in closely. 

Talk to the Master s/s 100 ++ was the quickest finisher and is worth following when next he goes over a stiff sprint or better still, his favourite trip – 1400m.

One of the toughest beats on Saturday was Miss World with Adam Azzie’s new acquisition just going down in the finale. She was punted into 14/10 but stepped tardily out the stalls, sacrificing precious ground for a 1000m scuttle.

Though Miss World was able to sustain a rails run in a blistering, 21.7 seconds come- home sectional, forwardly placed, Rainbow Reward s/s 88, career best 94 (also by Rafeef) managed to keep going for the win.

Like the previous sprint, this also ended in a blanket finish. This raises an associated, albeit quite technical observation about race ratings.

Something traditional weight handicappers don’t consider is the course at which the races are being held. They plug in their standard formulas based on weights carried, the age of the runners, and lengths behind at the finish but to do so out of context ignores reality. 

Pace is an important factor, too. Slow early pace, where horses can conserve energy, often leads to more clustered finishes. 

But the central point is that beaten margins are greater at altitude on a exhausting, galloping course than on a tight, coastal circuit. Put another way, it’s far harder to win by a wide margin at Greyville, than it is at Turffontein

Soft going as opposed to a firm, glib surface similarly tires horses out to a greater extent, which “elasticates” beaten margins at the wire.

Yet classical weight handicappers treat the value of beaten lengths equally at all courses. By applying the same rating scale for finishing margins regardless of track, pace or the prevailing ground, handicappers are not crediting or discrediting horses by an accurate amount. This leads to flaws in the numbers generated.

The above critique is not dissing official merit ratings as meaningless. Just that a healthy amount of scepticism is justified given technical problems associated with their creation.
