We have a boatload of guys (pitchers) in MLB, or almost there, from the late rounds (for whatever reason):
Brieske, 2019, 27th round.
Garrett Hill, 2018, 26th round.
Chance Kirby, 2018, 25th round.
Brendan White, 2019, 26th round.
(Fernander and Chentouf in 2018, 35th & 36th rounds if either makes it to MLB as a reliever... not out of the question...).
Will Vest was a 12th in 2017, and we've also called up Drew Carlton, 2017 32nd rounder...
Who knows what the staying power is of any of these guys... but it's pretty remarkable, I think, to have this many late-round pitchers all of a sudden knocking at MLB's door, or already there... in the same time frame.
