Joinem, a 3-year-old Johar gelding, won his career debut last June at Churchill Downs by more than 10 lengths, and he has finished first or second in all four of his starts to date. Joinem was one of 10 horses entered in the featured eighth race Thursday at Fair Grounds, and he looks like a horse with a decent future, but forgive trainer David Carroll for being far more wrapped up in the present.
