Perkins as a hitter, might be AAAA, sure. But who are the alternatives? Wiemer? Roller? Brewer Hicklen is performing well in Nashville but lets not kid ourselves there is a reason the guy was a minor league free agent and has 4 career PAs in the majors at 28. And you cannot ignore defense, especially with this team. 10 OAA and a 23.6 UZR/150 over his 648 innings long MLB career are insanely good. Elite even.
Sanchez has a 0.340 wOBA and 120 wRC+ going into today. Top of the league in xwOBA, xBA, xSLG, Barrel% and HardHit%. He will never be an MVP but he is a very solid backup catcher.
