They have been counting the covid guys against the 60 for some reason. ERod is no longer on the roster they just sent with the release. My guess is that his timeline is so far out now that they're comfortable taking him off, whereas Taylor and Darwinzon are at least in Pawtucket working out.
"We really don't need the whole commercial break/warm-up routine every time a new reliever comes into the game. It certainly made sense in 1884 when they only switched pitchers when the starter was attacked by pickaxe or caught consumption, and no reliever was warming up because he was busy gambling and drinking." - JD
