Katie Mikolay, the Fair Grounds handicapping analyst, will be the featured guest Friday on the "Kentucky Derby Trail" live chat between 7-9 p.m. (ET). Moderated by five-time National Handicapping Championship qualifier Tim Holland, the question-and-answer chat will focus upon the biggest racecard of the year at Fair Grounds.

The $1 million Louisiana Derby (G1) highlights Saturday's program and Risen Star (G2) hero MUCHO MACHO MAN (Macho Uno) has been installed as the 9-5 favorite on the morning line among 13 three-year-olds. The $500,000 Fair Grounds Oaks (G2), a key prep for the May 6 Kentucky Oaks (G1), will match a contentious field of 10 fillies at the New Orleans oval.

Other races of interest this weekend include Saturday's $500,000 Spiral S. (G2) at Turfway Park and the $800,000 Sunland Derby (G3) on Sunday.
