In a league that starts tomorrrow I was granted a rather good crop of prospects. One of which is this guy:

Carlos Penrod: 9 contact, 7 power, and 7 speed. (He has terrible defense and stamina, and only plays OF)
He is based on '58 Leon Wagner who is worth 1.84M. Wagner batted .317/.371/.522 with 13HRs in 253 AB.

All of my outfielders are half decent, I have '90 Willie McGee, '30 Heinie Manush, and '88 Tony Gwynn, The thing is most of them have around 600 PA/162 so I'm not sure if my very good prospect (I am assuming) will get his max ABs. I am considering waiting until I have reliable lefty/righty splits for my outfielders and prospects and then inserting Penrod accordingly. Any advice?

Use him as the #1 pinch hitter and 2nd on the depth charts at the corner OF positions.

That's interesting, I had no idea about the lefty/righty splits. 

whats his HR#?  It seems like it would be high. Maybe place him in the lineup when playing in HR parks (maybe singles parks too) especielly against the opposite throwing pitcher. Seems like a good guy to platoon.
