Wilson Betemit – When Wilson Betemit was 15, the Atlanta Braves signed him to a contract.  He hit .212/.270/.283 in his first year at rookie ball and .220/.301/.399 his second year. He was just 16.

The following year he got his act together as an enterprising 17-year-old posting an admirable .320/.383/.463 line.
