TDN published the current list of European Based Sires according to their 3yo crop. With his Derby win there's no surprise that New Approach is top of the list, with Galileo, Siyouni and Camelot coming next. Frankel is not in the top 15. If Without Parole wins today he'll get into the top 10, maybe top 5.
Of course Cracksman winning tomorrow will make everyone feel better, but he's a 4yo so won't affect this list. Very disappointed by the PoW field as I'd love to see Cracksman properly tested on fast ground. The field doesn't make it much of a test.
