Looking over a FA list, here are the catchers available and their ops and fWAR last season.

Carlos Ruiz - .665 0.5 (54 games)
Geovany Soto - .676 0.0 (48 games)
Ryan hanigan - .671 -0.1 (33 games)
Hank conger - Arizona AAA
Chris herrman - .618 -0.6 (106 games)
Cameron Rupp - .716 0.8 (88 games)
Michael ohlman - .462 0.0 (7 games)
Tony Sanchez - AAA and 1 game for braves
Taylor Davis - .539 -0.1 (8 games)
Michael mchenry - rays AAA
Josh thole - .474 -0.5 (50 games)
Derek Norris - .638 0.1 (53 games)


Without looking at framing stats, I would call Ruiz, rupp, or Norris
