Can Vinrock win Saturday's Caulfield Guineas?

The track – unique features of Caulfield 1600m course, advantages PIR/barriers:

  • Rail True, Good 4
  • On pacers have an advantage at Caulfield with a win strike rate of 10.8%
  • Backmarkers are losing at 17% POT
  • Lane 2 is performing best with a 2% POT. Coming wider than lane 4 is very difficult

Speed map & tempo:

Expecting an even tempo (see image below):

Positive/negative jockey/trainer worth highlighting:

  • Nick Ryan and Declan Bates are returning 56.7% POT from their last 100 races.
  • Matt Laurie and Mark Zahra are also very profitable with 30.1% ROI.
  • High profile jockeys Damian Lane and Blake Shinn are riding their horses for the first time (Autumn Boy and Nepotism).
  • Jamie Melham is riding Navy Pilot again.

 

Past 5 winners with Racelab Performance Rating:

This table outlines the Racelab rating achieved by each of the past five winners when taking out the Caulfield Guineas. It gives an indication of the level required to win the race in recent years for a few different levels of weight carried. The rating is dependent on the WFA scale and factors in weight carried:

 

Date Horse | Age | Sex Weight Margin Racelab Rating
12/10/24 Private Life 3C 57.0kg 0.15L 105.2
14/10/23 Griff 3C 57.0kg 1.75L 107.1
08/10/22 Golden Mile 3C 57.0kg 0.2L 102.9
09/10/21 Anamoe 3C 57.0kg 0.5L 105.5
10/10/20 Ole Kirk 3C 56.5kg 0.4L 105.2

 

Racelab benchmark likely to be required to win this year’s edition of the Caulfield Guineas:

Based off the final field, their recent form, and potential Racelab Prime Rating, the below figures give an indication of what horses will need to achieve based on their weight carried under the WFA scale to win Saturday’s Caulfield Guineas:

Weight Rating
57.0kg 104.4

 

The Racelab Prime Ratings for each horse can be seen in the screenshot below:

 

The ratings/market:

Based off a range of data, speed map and recent form, Racelab has come up with its own 100% market, which is compared to the current market in the table below. Value exists where the Racelab price is lower than the current price:

Horse Rated Price Market
RIVELLINO 39 23
WODETON 5.4 3.9
VINROCK 4.5 7
NEPOTISM 29 16
WEST OF SWINDON 19 14
VEGA FOR LUCK (NZ) 161 41
HIGHVOL 55 31
NAVY PILOT 19 11
AUTUMN BOY 4.5 4
SPACE RIDER 55 34
PRESTIGE OLE 231 126
HILLIER 55 67
STAY COSMIC 79 51
PLANET RED 39 20
ROMANTIC ENCOUNTER 39 23
OBSERVER 32 35

The verdict and betting strategy:

They should run along at an even tempo here and it appears Vinrock will have to press forward from the wide draw to settle on speed. Under set weight conditions, Wodeton and Vinrock are ideally suited considering they would normally give plenty of weight to these in handicap races. The formline from the Golden Rose looks the strongest, however Wodeton enjoyed a dream run and Autumn Boy had excuses. You are getting a short price to be with either of them here. Vinrock has the best SP profile in this field – he’s never started over $3.8 in all six career starts! I like the fact he has a run over the mile under his belt now and should be peaking fourth up.

 

Suggested Bet:

Vinrock (WIN)

 

Name Definition
Prime Rating Expected rating figure for the upcoming race based on historical performances
Job To Do (JTD) The minimum rating required for each runner to win the race using a combination of metrics: Benchmark, Weight Carried, Mean Weight and Distance.
