I believe in clutch, it is a thing. If you have 1st and 3rd and 1 out he should be able to get that run in, that's clutch. Also lets not forget he was advertised as a good hitting catcher not just an average catcher with good defence.
He is hitting .185 this year, sure he has 12 walks but he has not been clutch. We pay him 85 million for 5 years to frame and play good defence? No he needs to hit.
