I'm old enough to remember when Scott Kingery was supposed to be Merrifield!
A town is not wrong about the manager but sometimes the GM has to save the manager from himself. Torreyes and Didi both got too much playing time late last season, though Freddy being injured didn't help (and it's not like he was a huge upgrade either).
But Williams hasn't lost his job to Torreyes - someone else would still have to come off the 40 for that. Torreyes was 0.6 Fangraphs WAR last season, but Maton was 0.5 - and in 1/3 the playing time (BBRef has Torreyes 0.2 and Maton 0.2 but had Maton played more he'd have been higher). Neither of them can hit a lick, of course.
I doubt Maton will also get DFA'ed. What's probably going to happen if they need to make room for another position player (be it Torreyes or Kingery or someone else) is they finally cut ties with Moniak.
They also chose to keep the extra catcher over Williams of course, so that would be the other route.
