If you're struggling on the higher difficulties, I'd recommend having 2 or 3 of the bunt cheese guys in your lineup, and the rest be high contact high vision and all 4 bench spots being 99 spd 99 steal guys if you got them. Neon Chandler Simpson and postseason Garrett Hampson both have 99 spd and drag bunting, as does HOF Honus Wagner if you got him, but id use him off the bench since he can play any position and is the perfect pinch runner for a slower batter.
Use guess pitch, I cant remember the name of the one, but when you guess the pitch and the location correctly the location lights up red. Pick the pitch you feel most comfortable with hitting and keep guessing it until you get 2 strikes. I wouldn't use it with 2 strikes, because in my experience the penalty for guessing wrong is pretty high even if you put the pci on the ball pretty good. And when you get to 2 strikes just swing away and hope for the best and use contact swing if you got a guy on in hopes of just moving him over.
Im not elite at the game, but I think im slightly above average and I dont struggle on HOF or legend difficulties the way I used too. But this is still a strategy I break out from time to time whenever Im feeling less locked in.
