Scouting Report

AssetsHas very good plate discipline, patience and sound overall batting instincts for a catcher. Will often walk more than he strikes out. Can get red-hot with the bat for long stretches.
FlawsIs not a great defensive catcher or game-caller. Doesn't have huge power. Lefty pitchers give him trouble more trouble, so he profiles more as a platoon player in the big leagues.
Career potentialSolid offensive catcher with great patience.
