While the Louisiana Derby (G2) is the marquee race on Saturday's program at Fair Grounds, the marquee horse competing on the card is reigning three-year-old colt champion Sierra Leone.

I'm Very Busy showed a glimpse of his improving quality when a narrowly beaten second to the world-class filly Warm Heart in the Pegasus World Cup Turf (G1) in late January. On Saturday at Fair Grounds, I'm Very Busy made it pretty clear he'll be a force to be reckoned with in the older mare turf division this season with a sparkling 3 3/4-length romp in the $300,000 Muniz Memorial (G2).
