I've managed to get to 99 as a 'Professor' for my created pitcher. I've noted now that I don't get offered to do my weekly training options between my game pitching slots. I was hoping to (a) improve my sub-core stats even further, (b) to improve my fielding, batting, running and bunting. Is there anyway I can do this if the mod-cycle training options are not available?
Training other areas as a Pitcher?

First, you might want to grind the other pitching Archetypes. In my opinion, Pedro is better than Professor.
Second, if you want to upgrade the position player attributes, you must be a position player. If they don't offer you the option of 2-way play, you can start a new career, either 2-way or position player only. This will allow you to upgrade your stats for your created player, and these will have impact across all your careers in RTTS.
