John Murphy has decided to supplement Big Time into Sunday's Keeneland Phoenix Stakes at the Curragh.
Heading the field for the six-furlong Group One is Aidan O'Brien's unbeaten War Command, who looked an immense prospect after his stunning victory in the Coventry Stakes at Royal Ascot.
Murphy paid €20,000 to allow the colt entry for a potential rematch with Sudirman, who beat him half a length in the Railway Stakes at the same course in late June.
Big Time had earlier made a winning debut at Naas and the Cork trainer said: "He has been working really well. He was in the Prix Morny as well but we decided he should take his chance here.
"The owner was very good about it. We are closely matched with Sudirman, I'm sure that horse will improve as well, but ours has done.
"He could easily step up to seven furlongs or a mile, but he has plenty of speed too."
O'Brien has won the race an incredible 12 times through the likes of George Washington, Holy Roman Emperor and Mastercraftsman as well as last year with Pedro The Great.
He has half of the 10-strong field, with War Command joined by Fountain Of Youth, the unraced Giovanni Boldini, Wilshire Boulevard and Bluebell.
Aside from David Wachman's Sudirman, the line-up is completed by Muscle Beach and Sniper.
