"Carpe Diem (6.90 AWD) would appear most likely of the remaining top 10 [first-crop sires] to benefit from increasing accessibility to longer races. The high AWDs... suggest that [his] progeny have won some relatively short races more because of sheet ability than preferences for the shorter differences typically available to 2-year-olds."
-BloodHorse MarketWatch, Jan. 25, 2020
"The impressive thing about Carpe Diem, to me, is his ability to run 5 ½ furlongs in a tough 2-year-old maiden race at Saratoga and then stretch out to win Grade 1 races around two turns."
-Todd Pletcher
"He has enough class and raw talent to beat anyone. He is a horse you just love looking at...all racehorse."
-Steve Haskin
"Carpe Diem gives me a sense that there is so much more to him that we haven’t seen yet. I’ve felt from the moment Carpe Diem went wire to wire in a 5 1/2-furlong maiden race last summer at Saratoga that he had to be unusually good, because what son of Giant’s Causeway would do that? All along I’ve felt Carpe Diem would only get better with distance and maturity, and I still feel that way. He’s winning races like the Blue Grass and Tampa Bay Derby decisively, and I don’t think he’s even begun to scratch the surface of his ability."
