A 33 round guy was a long shot anyways. Guys in those rounds are HS kids on garentee commits to major baseball programs. There was 0% chance he would sign and it was a pick used due to a lack of talent that deep into the draft.
I wouldnt be concerned on these guys signing
They aren't that long of a shot. Mitchell Parker was taken in the 28th round, has a u of tenn committment.... or did and there's a good chance he signs. Plus, if you look at alot of the players they drafted in the first 10 rounds they look like potential money saving guys. They've only signed 3 for sure afaik and nico hoerner is getting slot. Paul Richan is saving $312,900 and Luke Reynolds is saving $12,600. Supposedly Brennen Davis wanted 1.3-1.5 mil which is 240k-440k over slot. Chances are Reynolds and Richan already saves enough. Of the remaining guys in the first 10 rounds, roederer was drafted far enough ahead of his rating that I am safely assuming his $775,100 slot signs him. Jimmy Herron was drafted well above ranking and was a college junior. Ethan Roberts, Andy Weber, Kohl Franklin, Zach Mort and Derek Casey weren't even rated by BA/mlb.com. Kohl Franklin might take more than his $245,600 slot but the rest appear to be well below slot guys as college juniors/seniors. D.J. Artis was rated 149 and 136 by BA/MLB.com and fell a tad to 218. He's a college junior coming off a bad year so think slot or maybe a touch over should be easy enough to get him.
Point here being, it wouldn't be that shocking if they had more than ~$1 mil in under slot signing. If you assume $300k of that is going to Davis and $400k(+$125k) goes to Parker worst case, that still leaves you with the ability to offer someone like Ras roughly $425k. That's 4th round money.
Am I super upset he didn't sign? No but I thought with the way they structured the top of their draft they would have a shot to sign one or two of these interesting late round hs guys.
