Kiley McDaniel's Top 50: https://www.espn.com/mlb/insider/story/_/id/31958336/kiley-mcdaniel-midseason-top-50-mlb-prospects
Blue Jays have 4 in the Top 50, with 2 more in the honourable mentions.
12. Alek Manoah, RHP, Toronto Blue Jays
Manoah was another player like Alvarez for whom I just wanted to see a little more pro performance before I shot him up the list, and now he's a start away from losing his prospect eligibility with a 2.47 ERA in the majors and is only a little bit lucky.
22. Nate Pearson, RHP, Toronto Blue Jays
Pearson is right there with Hunter Greene for the best raw stuff among starters in the minors. Pearson has been just OK in the big leagues and slowed this year by a sports hernia.
36. Gabriel Moreno, C, Toronto Blue Jays
Moreno is a solid defender who is 21 years old and performing at a career-best level in Double-A this year, flashing above-average contact and power upside.
38. Orelvis Martinez, SS, Toronto Blue Jays
Martinez is a teenager who just got promoted to high-A and already has 20 homers this year, with easy plus raw power that's really showing up in games. He'll likely slide over to third base down the line. Contact is a bit of a question, but the bat speed is elite.
Honourable mentions:
Alejandro Kirk, C, Toronto Blue Jays
Jordan Groshans, SS, Toronto Blue Jays
