Blue Jays' Top 30 Prospects | Breakdown
Top 100: 5 – Vladimir Guerrero Jr., 3B (1); Bo Bichette, SS (11); Danny Jansen, C (65); Nate Pearson, RHP (76); Eric Pardinho, RHP (98)
Prospect Points (MLB Rank): 254 (7)
The mere presence of Vladimir Guerrero Jr. -- MLB's No. 1 overall prospect and one of the most vaunted hitting prospects in baseball history -- makes the Blue Jays’ farm system noteworthy. But it’s the organization’s deep crop of potential impact talent -- both hitters and pitchers -- that has its system up three spots from last year’s preseason list. The Blue Jays' commitment to scouting and player development is reflected by the number of homegrown players on the club’s new Top 30. In total, 24 players have entered the system via the Draft or as an international signee, and that includes every player in the top 13 spots on the list.
It's noteworthy that updates during the second half of last season included more of the players the Jays traded for, while this new list is really heavy on internal draftees and signees, bumping some of those trade additions right out.
