Looking at the schedule, it seems like he could make 3 starts at AAA before the end of the regular season. So he's likely finishing right around 100 IP. There seems to be a pretty good chance of the Bisons making the playoffs he has the potential to pick up an additional 20+ innings.
After 100-125 IP in 2019 one would have to assume they wouldn't quite be ramping him up to a full 170+ inning load in 2020.
