Have a Top 100 Prospects list, like something Baseball America does. You could start out unranked and work your way up the list as you progress. Then, let's say you are a batter ranked in the Top 10 and you're facing a pitcher in the Top 10, the commentators would talk about it and you could earn extra training points (ala NBA 2K). Being higher on the list would improve your chances of being called up, and your team would value you more. There could also be scouting reports and such on all of the prospects on the list. Maybe even be able to earn bonus stuff/rewards if you get ranked in the Top 10 or even number one.
