In our past couple annual surveys of the most profitable turf sires in North America we were surprised to find a small number of stallions whose progeny have put bettors on the green in the black.
In 2018, for example, only two sires - Quality Road and Giant's Causeway - showed a positive Win Return with their grass runners. As the chart below shows, that figure doubled in 2019 with Stormy Atlantic, his son Get Stormy, Into Mischief and Hard Spun all showing in the plus column.
The chart also shows that Hard Spun had the highest turf Win % and Twirling Candy was tops in In the Money % (42.25%) by a slight margin over Ghostzapper ($45.22).
