I don‘t think I’d want to go any lower on the list for a non-40 starter anyway. With Hendricks coming back, Taillon looking like a short stint on the IL and all, I’d rather save those 40-man moves for guys like Sanders, Burdi, Nittoli, Kay or whoever is still throwing well when the need arises.
The Cubs are a bit limited on the 40-man until they make complete decisions on some of the fringe roster guys. Some decisions might be made earlier, but a lot of times, teams want to see 40 games to really get a good read on guys. I think the Cubs really only have a couple pitching slots potentially “open” right now (though with the shuttling back and forth with AAA, it can be a bit more) and maybe 4 position player active roster spots. I think there are very real questions on Merryweather, Fulmer, maybe Rucker and then on the position side, Hosmer, Rios, Torrens and maybe Madrigal. After those guys, the 40-man guys not on the active roster are all young players that the Cubs aren’t going to want to cut.
