I had a 19 year old phenom that was 8/8/8 in talent on 2-8. Put him in the majors immediately. He did well for the first 11 years but faded quickly and was done by age 32. Did finish with 392 homers in 14 years and a solid .292 average. I then took a back up of the league and kept him in the minors for 2 years bringing him up at age 21. This made a big difference. His initial years in the majors were not as impressive but he played longer and had better seasons when he was 26-30..... Finished with 603 homers, .314 average in 17 seasons......funny thing he only had about 700 more at bats playing in the second scenario.....

I noticed that his ratings were dropping at age 27 in the first scenario (his 9th year in the league) and this is normally the time when a player gets better. Maybe the game engine is based on years and plate appearances (usage) and not necessarily on age... I had player mods set at 125% for development and 25% for aging....
