I am no coach first off lets get this straight. But if it is against a spinner and you are not a good cutter, there surely must be enough time for you to note that the ball will pitch wider when it is released and try to take a pace across and play the ball like a straight delivery maybe? If not, leave well alone, no harm done depending what the match situation is.
Or could try to net with someone who put balls down to you at a constant wide''ish delivery and practice practice practice. Only true way you will get the feel for this shot.
Try not to get frustrated with yourself if you do practice this. When practicing certain aspects of shots you are weak with, being in a bad frame of mind makes it harder, try to enjoy it.
I used to struggle with short deliveries, but had an extra net at training for a long while and had ball put down to me at throat height, now i am really comfortable with bouncers and short pitch deliveries at decent pace. Practice is the best way.
