I think he would make 3 more starts in the minors. They will probably ramp up his pitch count by 10-15 pitches each time. He is at 40 pitches after this start so we can expect him to go 50-55 pitches next and then see a couple of 60 -75 pitch starts. This would allow him to come back to majors with 80-85 pitch limit which would be perfect.
We should expect his first MLB start this year to be on August 4-5 at Detroit if everything goes well. If they want to bring him back during a home series, they will have to wait another week when vs TB series starts on 8/10.
