They say the Derby track is a mess at the moment. But the rain seems to be moving out of the area, so perhaps the track, sealed and groomed and sealed and groomed yadda blah, yadda blah, will be vastly improved by the 10th race.
But if not, an off track alters the picture a little. For one thing, Tale of Ekati doesn't appear to care for an off track. In the two times he ran in the wet, he didn't even hit the board.
However, Pyro LOVES a wet track. So do Visionnaire, Cool Coal Man, and Smooth Air. Oh, and Denis of Cork, too, though that 16-hole post is a bit out there.
If Big Brown is as good as he appears to be, a wet track oughtn't be a big deal, but it is a question mark for him. Same goes for Colonel John and, actually, for any of the synthetic runners untried in the wet.
I think a Pyro-Big Brown-Visionnaire exacta box could be worth playing. And here's a cheap $4 "wet track" superfecta (note it leaves out Cool Coal Man; if you have more $, put him in): 9,20/9,20/8/12,16.
Time to break out dem mint juleps! Good luck today, all y'all.
