Training a yorkie can be very challenging sometimes. I had the same problem with Snickers pooping in the crate and stepping all over it. But he gradually grew out of it. Dogs won't potty where they sleep, but puppies aren't dogs yet.
I was told that puppies cannot control their potty functions until they are six months old, and I did see a major improvement after six months. So hang in there! Keep up the crate training and try and get him out before he poops, if you can. Both of my yorkies were not fully potty trained until about 8-9 months.
