Funny thing was I was half way though the first season in AA then just got called up to AAA.
Didn’t play it for ages but did play loads of DD so my ball player got to an 85 or so with equipment
Went back to RTTS to grind some more stats to 50 about 2 weeks ago and then after about 7 games I got called up to the majors.
Pretty sure you can do something similar and see how far you can push the early call up.
I.e draft but never play a game go into Dd get your player to as high as equipment will allow then go back to RTTS
(I only play in beginner because I like to pretend I’m that good)
