What's interesting to me is that Servis is not alone. The overall stat for new tops by first time Lasix horses is 45.6%. First time blinkers is right behind with 41.9%.

Of course, with both of these stats, one has to wonder how much they are skewed by that fact that much of the sample is 2yos, who are at an age when they are likely to run new tops anyway (35.6%).
