Covelj,
Probably best for MJ to answer, as on this board he is the biggest Paddy O proponent, but I think it is a pretty easy answer, to be honest.
With apologies to Michael D, who picked this horse in the Bluegrass, most of the rest of us saw a huge unexplainable jump up on synthetic in the Bluegrass, for a horse who is bred better for turf and synthetic than he is for dirt.
Whereas Paddy O shows a steadily improving line, with newfound tactical speed, which made him look like a solid play in the bluegrass and he ran well there. He is by El Prado, so no reason why he can\'t dirt. His \"bad\" dirt race was his first lifetime start, which can be awful for many horses.
So, in summary, SV was a one time \"jump up\", bred for synth/turf, while Paddy is a steadily improving horse, who can potentially run as well on dirt as he does on synth/turf (by his breeding).
And \"yes\", he got the only \"wow\" workout report from Welsch.
