Probably not.
I mean, maybe. But the odds are we haven't. That's not a slam on him, that's just how baseball works.
Yesterday was a decent start, IMO, not a great one. He went 5 innings, threw 91 pitches. He struck out 4 which is okay, not great, but he also walked 4, too.
He pitched out of two bases loaded jams. IMO, that's not a recipe for success. I said it in the game thread but I'll say it again here; it was a pretty cool highwire balancing act.
Now I will say he probably didn't have his best stuff and he battled and figured out a way to get out of his jams. He battled, and that's great. But we still need to see more of him to see if we have something or not. The history of baseball is littered with guys who came up and had some initial success but couldn't sustain it. For every John Means you get, there's dozens of Josh Towers.
This isn't to say I don't want to see more of Ellis, I absolutely do. But there are warning signs, he's struck out 11 in 17.2 innings and he's walked 8 in Baltimore. That's not great and with those k/bb rates a 2.08 ERA isn't sustainable. His FIP is 5.08.
