I created a starting pitcher and made it to the majors in 8 games.

I had the same thing happen to me, I have a SS that is in his second month in AA and hitting .360 12hrs...lol

That's some luck right there!   Did they keep you as a SP? 

I played like 5 games in AAA as a CP and then was called up.  I was a SP for about 1yr in AA.  Very frustrating to gain Training Pts as a RP.  too many damn loading screens between games.  Gathering some info, I need to focus efforts on Durabaility and arm strength to prove I can be a SP stat wise.  Probably need to be at least a 75 OVR as well. 

My recommendation to others reading, don't go with 5 pitches, max of 4, so you can spend your hard earned training pts in other areas.  Maybe try and stay with 3 until you get called up.  FSB, slider, circ change so do well enough for options.
