I have a delima here. I am 6 games out of a wild card spot with 72 games to go. I have made 3 trades to make my team a lot better, but still have a need for a solid outfielder.
I have
Britt McGriff in the minors, who could help my team right now. He is generally within 10% of his projections, except his splits against righties (11 more to go) and a couple of his defensive ratings. I spent 18 million on adv. scouting this year, and 20 million last year, so I feel fairly comfortable with his projected ratings.
I have gotten mixed reactions over whether bringing up a prospect to the ML level slows their development. Some say after year 4 development slows, others (including a comment in a dev chat) says they develop better in the minors. Just in my limited experience I tend to believe they develop better in the minors, so at this point I would prefer him to finish up this season at AAA, wait the 20 days next year and bring him up.
Here is my dilemma. If bring him up th is year for a playoff run, demote him back to AAA next year before spring training starts, and let him wait 20 days + service time this year, so he finished up next year with less then 172 days of service time, will that affect his growth at all?
