Let's look at the past few years of position players that were drafted:
Nasim Nunez - AA 125 games
Deyvison De Los Santos - AA 113 games
Ryan Noda - AAA 135 games
Blake Sabol - AAA 25 games
Akil Baddoo - A+ 29 games (post COVID year)
Kyle Holder - AA 112 games (post COVID year)
Ka'ai Tom - AAA 51 games
Mark Payton - AAA 118 games
Vimael Machin - AAA 12 games
Jonathan Arauz - AA 28 games
Five guys drafted prior to reaching AAA. Ignoring the weird COVID year impact on Baddoo, most guys played at least a full year at AA or reached AAA before being picked. The only exception was our boy Arauz. My guess is that the Sox picked Arauz to help with the MIF depth and then with the truncated season it was just too easy to hold onto him. Didn't work out though.
I think someone could look at Garcia and think they could turn him into a Baddoo, a guy who had one strong season and now is just kind of a backup role player. For a Rule 5 pick that basically costs you nothing except roster space, it could be worthwhile for the CHW, OAK, or a bunch of other teams that need/like to hoard young cheap labor.
