Here's one from my fictional league, but I didn't bring him up right away. Instead, I let him go to AAA after the draft to see how he does--I was convinced after only 17 games. In his first year (year 2015), the same year he was drafted, he played 59 games in the majors, backing up for a good defensive CF (but the guy was below average with the stick [sub .300wOBA]).
The rookie did good with the backup role, so the next year, I decided to give the starting role to him.
In his official rookie year (the following year, 2016), he played 160 games, hitting over .300, with 20 homeruns, 100+ runs, 200+ hits, and 25 stolen bases. Needless to say, he won the rookie of the year award. He also won 3 rookie of the month awards, the gold glove with a +46.2 ZR in center, and played in the all-star game.
He was 23 y/o when he was drafted 26th overall by the Padres from Central Michigan. 12 days later, he signed with the Padres--a $1,730,000 signing bonus and a 3 year contract worth $2,400,000.
