Have you been applying the ability and skill points to your player?
Just bowl over after over of short bouncers and youll level up and get noticed in no time!
Btw, you get very little to zero ability points most (all?) of the time when you simulate without actually entering the match. You seem to get a random 50 odd bonus to batting xp after bowling well first, then winning without having to face any balls yourself. Theres also a random 30-40 fielding bonus xp sometimes awarded, I can only theorize that its while bowling and sometimes you stop a 1 ball that would have gone for 2, or even stop a single and force a dot.
Tldr: Dont sim anything for maximum gains, especially your ability points. Apply your accumlated ability and skill points. And of course, fielding in CR19 is a rewardless standing around simulator.
