Thats what he would do anywhere.  He needs to build up reliever amount if innings this year around 60-70. Next year he should be on the kopech plan of 100-120 with multiple inning outings either in the minors or majors. The issue with crochet he could just throw fastballs down get away with it in the minors. At least in the MLB he will learn to get MLB hitters out. If his luck changes.
