Chris Nelson was thought by many to be a lock to open the 2013 season as the everyday third baseman, but a strong spring by 21-year-old prospect Nolan Arenado has put some pressure on the incumbent. Arenado is hitting .308 with four home runs in 26 at-bats in the Cactus League while Nelson has started off slowly with a .192 average and no home runs.
MLB.com’s Thomas Harding cautions that Arenado is still not guaranteed anything if he keeps it up over the final two weeks:
Even if he deserves to make it, the Rockies will have to decide whether to put Arenado in the Majors in the beginning, or delay the callup to avoid starting his clock toward arbitration and free agency. With so much out of his control, Arenado’s maturity is already being tested while he tries to impress manager Walt Weiss and the big league coaches and club officials.
Arenado, rated the #52 overall prospect by Baseball America, got his first taste of Double-A last year with Tulsa, hitting .285 with 12 home runs.
