The one catcher that might strike the most interest for the LA Angels because they have a good relationship with him, is previously mentioned Martin Maldonado. The Angels had originally drafted Maldonado back in 2004, so he obviously knows the staff well and has fallen back into the Angels lap before after a trade with the Milwaukee Brewers.
His experience with other teams could prove beneficial to the Angels because he’s worked with other pitching staffs before, especially the division rival Houston Astros, who he has been on twice.
Currently, the Angels have 3 catchers on their active roster which are Max Stassi, Kevan Smith, and Anthony Bemboom, and if they are to make improvements to their starting rotation, they need a good complimentary piece in terms of a solid catcher that is good with framing and controlling a pitching staff.
