GO GET THE MUNNY Trainer: Tom Morley Last race: Feb. 1, 5th Finish: 1st by 7 1/4 Beyer: 81 Three-year-old gelding showed up for his debut with a series of strong works in tow, took plenty of early money, then proceeded to run away from a field of maidens with a strong Beyer of 81.   MARCONI Trainer: Todd Pletcher Last race: Feb. 3, 8th Finish: 3rd by 2 1/2 Beyer: 83 Three-year-old stepped up to try the Grade 3 Withers following an impressive maiden win and he acquitted himself well while gamely trying to close ground in the stretch over a track that was carrying speed all day long. The $2 million colt has some improving to do, and he will have to find a way to start breaking more alertly, but he is lightly raced and retains plenty of upside as he continues down the Derby trail.
