Blue Jays have 18:
Deiferson Barreto, Andy Burns, Patrick Cantwell, Ryan Dull, James Dykstra, Conor Fisk, Gabriel Guerrero, Mac James, Jesus Lopez, Mike Nittoli, Juan Nunez, Norberto Obeso, Willy Ortiz, Connor Overton, Tom Pannone, Luis Silva, Mitchell Walding, Forrest Wall
I guess Pannone & Forrest Wall are the ones of note.
