Nelson has a minor knee injury and is expected to be ready for game action by the end of April, MLB.com's Mike Rosenbaum reports.

EDGE Analysis

Nelson was held back in extended spring training due to the injury, and while Rosenbaum did not specify which level he will head to, High-A seems most likely, as the 20-year-old third baseman played 102 games at Low-A last year. He has a lightning quick bat and at 6-foot-2, 180 pounds, he should eventually grow into 20-plus homer pop.

Nelson, 19, is hitting .361 with nine RBI over his last 10 games for Low-A Greensboro.

EDGE Analysis

A 15th round pick last season, Nelson is raking during his first taste of full-season ball. He is batting .311/.356/.458 through 91 games. Nelson does not have big power or speed, and he could stand to be a bit more patient at the dish. Still, it is difficult to argue with his average, and he could move quickly up the ranks for the Marlins due to their lack of depth in their farm system.
