#25 Nolan Arenado
Previous Rank: N/R
Arenado was recently named MVP of the Arizona Fall League after slashing .388/.423/.636 with six jacks in 121 at-bats. In the California League as a 20-year-old, Arenado posted a .298/.349/.487 line with 20 home runs and 32 doubles as well as nearly as many walks as strikeouts. We expect Arenado to open the year in Double-A, and debut some time in Denver in 2013.
Arenado’s defense has been under scrutiny since he was an amateur, but he cut some weight last winter and improved his mobility in the process, silencing some doubters. I am not convinced that he can be average at the hot corner yet, but he is definitely good enough to play at least a few seasons there before sliding to first. His bat plays anywhere and has room to improve in the power category as well. His speed is not even close to average, but it never has to be.
Arenado is as exciting an infield prospect as exists in the game today, and he should make several all-star teams before he is done leaving his stamp on the NL West.
