The nuance of this situation that the green racing fan may not understand is how trainers behave disingenously to gain advantage.
On the surface, yes, this is just a trace amount of a prohibited but otherwise benign substance. On the surface, yes, there is a totally plausible explanation for how and why it got into the horse’s system. On the surface, no, it didn’t affect the outcome of the race. On the surface, Baffert’s other recent positives also have plausible explanations and also were at levels that didn’t affect the outcome of the race.
But just because all of that is true doesn’t mean Baffert is an innocent man being unfairly targeted.
Besides the obvious fact that he raced horses on banned subsances, these patterns are generally the symptom of a bigger problem-- the abuse of legal therapeutic medications while training. It’s a rampant issue that is challenging to address because these therapeutic medications have benefits that improve the quality of life for all racehorses. Yet a significant number of trainers (in all disciplines, but we’re focused on racing) find ways to overuse these products to enhance training and therefore performance. But ultimately, the constant onslaught of pharmaceuticals is detrimental to the animals, sometimes with catastrophic results.
If we are ever to address the issue, we need to stop celebrating people whose success comes from the practice.
