5. Bailey Falter

Falter has not had an ideal spring training, posting an ERA of 18 at first glance this is horrible but he has only pitched 1 inning which dulls the pain. Falter has posted an ERA of 3.16 through his minor career which is actually better than Spencer Howards ERA of 3.28 who was called up for 6 games last year. With Nola, Wheeler, Eflin, Howard, and possibly Medina the pitching rotation could get a little crowded so possibly moving Falter to the bullpen could help him adjust to the majors.
