Pletcher - Barn Virus?

[tywizard]

Pletcher admits there is a virus impacting his barns and suggests he has those affected in quarantine.

I posted this on Twitter and feel it's worth discussing.

He had 12 runners on Saturday. 3 wins and 5 last place finishes. Six last place finishes if you consider Effinex to be a non runner. Nevertheless, if you wagered $2 to win on all of his entries ($24 total) you would have gotten a healthy $43.50 in return.

If you toss the horses in the $1 Million Grade 1 races - You get 3 wins and 3 last place finishes. Investment of $16 returns the same $43.50.

So are the results on Saturday potentially due to a virus, testing or just normal all or nothing from the barn??
