This D. Wayne Lukas-trained horse has finished in the money five times in eight career starts, including all three starts this year.
Dublin (21-1) is coming off a third-place finish (behind Line of David and Super Saver) in April 10's Arkansas Derby. However he hasn't won since his first two starts, the last time coming in September of 2009 in the Grade I Hopeful Stakes  at Saratoga.
The son of Afleet Alex, who is owned by Robert Baker and William Mack and ridden by Terry Thompson, will be coming out of the No. 17 post position.
Dublin, who is 0-for-1 on wet dirt and 0-for-2 at Churchill Downs, has lifetime earnings of $408,623.
