Last non-BC race to have three horses coming in off G1 wins?
 

So anyone have any idea of the last non-BC race where there have been three horses coming in off G1 wins? I'm guessing it was when 3yo restricted horses met elders so am also curious when the last time it happened with all horses winning in unrestricted race. Also, last time we've had 5 G1 winners in a non-BC field? Hopefully the weather cooperates and the Sword Dancer takes place cause it has the potential to be one of the better races we've had in a few years.

Are we bored tonight?

How about the Ky Derby? That usually has a bunch of horses coming in off grade 1s. Wood, Fla derby, SA derby and BG.

Yeah, I guess I should have excluded the Derby, still doesn't answer the question of last in races not restricted for age G1s.

Are you saying the Sword Dancer is a race with three horses coming in off G1 wins?
If so, who am I forgetting? I know Red Rocks and Dancing Forever are both coming off G1 wins, but is there also a third one that I'm not thinking of?
I know Presious Passion won a G1 earlier this year, but his last start was an out-of-the-money finish at Monmouth on Haskell day.
