There are currently 22 pitchers on the Twins 40 man roster (plus 3 on the 60 day DL). I will assume that will be the case when the roster is set this November. These are the guys on it now, including the DL guys, that are pretty certain to be on it in November: 1) Jose Berrios 2) JT Chargois 3) Tyler Duffey 4) Pjil Hughes 5) Felix Jorge 6) Trevor May 7) Adalberto Mejia 8) Mason Melotakis 9) Ryan O'Rourke 10) Taylor Rogers 11) Fernando Romero 12) Randy Rosario 13) Ervin Santana Duffey and Santana would be the least certain of that group. In Duffey's case, it will be dictated by his performance. In Ervin's, based on whether he is traded. Of course, if Santana is traded, it seems pretty likely that whatever pitcher he is traded for will be on the 40 man. These players are on the bubble: Buddy Boshers Kyle Gibson Justin Haley Ryan Pressly Hector Santiago And that doesn't even include guys that are almost certainly goners like Belisle, Breslow, Kintzler, Perkins, Rucinski and Tepesch. While I would be pretty surprised if all 5 of the guys listed above are back, I'd be pretty surprised if all were gone too. My guess is that two are back. As best as I can tell (and I could certainly be wrong), these minor league pitchers will need to be added to the 40 man roster no later than after this season - some could be added before that obviously. 14) Nick Burdi 15) Stephen Gonsalves 16) Trevor Hildenberger 17) Jake Reed 18) Kohl Stewart Technically, that list would include Lewis Thorpe as well. But seeing as how he has never pitched above low A ball and hasn't pitched anywhere since 2014, I figure he will be exposed - of course low A ball is where Johan Santana had last pitched before the Twins plucked him. There could be more of which I am not aware. Anyone? So, if the Twins do indeed retain 2 of the "bubble" pitchers, that would put 20 pitchers on the 40 man. Not a lot of extra space. Indeed, they may need to cut down the number of pitchers for some position players. Park is still under contract through 2019. You would have to think they will give him another shot at some point, but Falvey may also say "not my problem" and convince Pohlad to eat the $ 8 mil or whatever he is still owed. 18 position players on the 40 man seems dangerously low when you have 12 or 13 of them active on the 25 man roster. Not a lot of wiggle room in case of injury. My point in all this is that unless Stewart does in fact turn it around this season, he might very well be exposed to the rule 5 draft.
