As it stands, the Toronto Blue Jays currently have two prospects who rank within the top 100 prospects list per MLB.com. Nate Pearson and Jordan Groshans sit 10th and 67th respectively, with both players being acquired through the annual amateur draft.
While these two players did not come through international free agency, the Blue Jays have been very active in this market and have had success through this method of free agency.
For example, former top prospect Vladimir Guerrero Jr. was acquired through this method, as well as infielder/outfielder Lourdes Gurriel Jr.
