After a spring/summer of North American racing we have the initial returns on the new sire class of 2018. Betmix Angler's Sire Search feature allows us to parse the data so far and the chart below shows results for stallions with at least 15 starters through September 24.
Spendthrift Farm's Cross Traffic (by Unbridled's Song) leads his crop in the early going with a 26% Win rate and profitable Win & Place Returns. Half of his runners have finished in the money, indicating there could very well be more winners in the near future for the 2013 Whitney H. (G1) winner. The progeny of Hopeful S. (G1) winner Strong Mandate, a son of Tiznow, may also bear watching as he ranks second with a 20% Win rate and full 60% of his runners have hit the board.
Revolutionary (by War Pass), winner of the Louisiana Derby (G2) and Pimlico Special (G3), has been the most profitable First Crop sire so far with a $69.40 Win Return buoyed by a pair of big-priced debut winners - Esterina in a Waiver Maiden Claimer at Delaware Park and Maiden Beauty, the $47.60 winner of the Lynbrook Stakes at Belmont Park.
