One of the newest Jays, Travis D'Arnaud, is handling the catching duties in Dunedin. D'Arnaud does have a wide catchers frame.
The Lansing catching duties have been split between Sean Ochinko and Jon Talley.
First we have a photo of Ochinko.
And here is Talley.
Carlos Perez was injured in March and could not compete for a Lansing job. As I mentioned in my comments from Dunedin, Perez is one of the smallest catchers in camp, I don't think he is as big as the six feet the Blue Jays claim. He looked about 5'9" or 5'10" to me.
Santiago Nessy is a young catcher, who is approx. 17 (not sure of DOB) and who signed last year out of Venezuela by the Jays. Here are a couple of photos of the youngest catcher. Again he has a wide catchers frame, especially given his young age.
