I mentioned in the game thread last night that I felt better about Williamson's debut because Casali was catching so I decided to look up the catcher ERA for the Reds so far.
Maile 426 PA 6.21 ERA
Stephenson 704 PA 5.48 ERA
Casali 503 PA 3.18 ERA
Yeah there's some small sample size, but Casli has been excellent his entire career even on the lousy 2018 Reds pitching staff.
