How many aces have the Twins home grown in 60 years of baseball? Kaat, Blyleven and Viola by my count. You could stretch it to include Santana (originally an Astro) and Pascual (pre arm trouble). Home grown aces occur infrequently, thus all acquisition avenues have to be examined. I too would not include Balazovic, Larnach, Kirilloff or Lewis in a deal for Snell. Possibly a package built around Duran or Garver. If the Twins' farm is as deep as believed there is significant value beyond the top four or five.
