At The Fish Stripes - Marlins Series Preview before the series vs. the Nationals, we barely touched base about the catching situation. I really want to be brief this time so I'm going to let the numbers talk:
Jacob Stallings: .118/.178/.162/.340 / 0 HR / 3 RBI / -5 OPS+ / 0 wRC+ / -0.8 WAR
Nick Fortes: .207/.261/.244/.505 / 1 HR / 6 RBI / 41 OPS+ / 45 wRC+ / 0.0 WAR
Defense (Team Stats):
Stallings: 23 GP / 9-14 Record / 73 - 127 RS - RA / Runs Allowed Distribution: 0-3 RA = 6 / 4-6 = 12 / 7+ = 5
Fortes: 22 GP / 14-8 Record / 85-84 RS-RA / Distribution: 0-3 RA = 11 / 4-6 = 8 / 7+ = 3
Statcast Framing and Blocking:
Stallings: -2 Catcher Framing Runs (53th place out of 57 qualified C) / +1 Block Above Average (13th place / 63)
Fortes: +1 Framing (9th place out of 57) / +6 Blocks Above Average (4th place / 63)
Miami is dead last in offense from the Catching position; although Fortes is not an offensive threat, he definitely deserves a lot more playing time than Stallings, seen from ANY aspect of the game. There is no A SINGLE stat in which Stallings is better than Nick.
If this team still consider Stallings valuable and don't want to release him, then at least reduce his catching duties. At this point, there is only room for improvement for him, but he needs more time off the field.
