2/3 of the 2020 season is 40 games... yeah, that's nice to get out of a minor league free agent, but it's nothing to write home about. Pretty telling if that's one of the primary success stories for the FO in 6 years.
But we've been saying that for years, and yet this season we've had to trade for Gray, Paddack, and Mahle, and had to sign Bundy and Archer... and we'll probably need to add more for next year as well.
As for the current pipeline... it's Varland and Woods-Richardson, and then not much on the horizon. MLB.com's last update placed the Twins farm system at #23 and I agree that it's in the bottom 10. There's certainly no starter prospects who profiles as a future ace, which is something we've been hoping that the new regime would be able to find since Cleveland developed the likes of Clevinger, Bauer (yes, I know he was traded) and Bieber.
