Garver, Sanó, Polanco, Gordon, Arraez, Kepler, Buxton, Rooker, and Duffy and Jax (also Eddie Rosario, Lamonte Wade Jr., Berrios, and Chargois who sadly are gone) ALL came from the Twins farm system - PRE-FALVINE, who came in October, 2016.
Falvine brought in Ober and Jeffers (who got the chance due to Garver's injury). That's not much - but it's still early, right? Five years.
