Nick Zito announced Sunday that Pat Day will ride A P Valentine when the son of A. P. Indy makes his 2001 debut Feb. 17 in a 7-furlong allowance race at Gulfstream. Jorge Chavez had been the colt's regular rider."It has nothing to do with 'Georgie,'" Zito said. "He'll still continue to ride Albert the Great. He rides with a lot of fire and desire, while Pat is not as aggressive. Pat's been around the block and has ridden a lot of great horses. I love this horse and I want to protect him as much as possible."Zito was thrilled with A P Valentine's 5-furlong work in :59 Saturday, in which the colt blew by his workmate and drew off willingly. "That was a great work for him," Zito said, "and it was nice because the coach (owner rick Pitino) was there."
