Late in 2018, Blue Jays fans got to see a glimpse into the future behind the plate in Danny Jansen. It is well documented that once he figured out his eye sight issues his offense soared. Management was so convinced in Jansen that they elected to move Russell Martin in the final year of his contract so Jansen could get as many reps in 2019.
Behind the plate Jansen has done very well, as he has allowed just four passed balls in well over 800 innings. When you compare that to the greats like Yadier Molina, Ivan Rodriguez and Russell Martin he had less then all of those guys in their rookie seasons while Jansen played more innings.
