Marco Hernandez, ss, Cubs: The Cubs have added a wave of Latin American talent to the lower levels of their farm system. As a result, the organization now faces a dilemma, albeit a good one, in trying to sort out playing time for Hernandez and Gioskar Amaya with its Rookie-level Arizona club. Amaya, an 18-year-old from Venezuela, has played mostly second base, though he's also spent time at shortstop and third base, while Hernandez, an 18-year-old Dominican, has been the primary shortstop but also has played a bit at second. At the plate, they have both excelled in their U.S. debuts. Amaya is hitting .390/.427/.476, showing advanced baseball instincts for his age. Hernandez is the better athlete with a more lively, projectable body (6 feet, 170 pounds) and has hit .310/.355/.410 through 24 games. Hernandez has good bat speed from the left side and shows good bat-to-ball ability, though he projects more as a doubles hitter than a power threat.
