I don't recall seeing anything either way on his change-up this year, which I take to mean as neither a good or bad thing. And it's entirely possible I could have missed something. He's actually done really well against lefties this year, but you'd think that if he had made significant progress with the pitch, it would be out there somewhere. I also don't have my BA Handbook with me at work so I'll look when I get home, but FWIW, MLB Pipeline has his change currently at a 45, and his curve at a 50, so actually neither pitch is really mind-blowing. Fastball is better than either, at 60. Just one observation, but it's out there. As a comparison, Giolito has a 70 CB and 50 CH, Urias has a 65 CB and 60 CH, Glasnow has a 60 CB and 50 CH, and Matz has a 50 CB and 60 CH. Again, as this alludes to, if he is going to move into that top tier of pitching prospect, the change-up has to come along more. I'll be interested to see what the end of season ratings have him at for his offspeed stuff.
