Wacha is a hold — league average, stable, no edge either way.

His expected ERA is 4.13, almost exactly the league average of 4.10. The sample covers 487 batters faced, well past the point where xERA becomes reliable, so this number is steady. His actual ERA is not part of this analysis, but the skill metrics — strikeout rate 19.7%, walk rate 7.0%, swinging-strike rate 10.6% — all hover around the league mean. Contact suppression is fine: hard-hit rate allowed (36.4%) and barrel rate (6.3%) are both below league average. No luck stat is swinging the line dramatically; nothing is driving the line up or down. He is what the numbers say — a roughly league-average pitcher. There is no buy signal and no sell signal. If you own him, keep him. If you don't, this is not where the edge is. Hold. 54 K with a 4.12 ERA is a streamer at best; hold if owned, leave on waivers in standard formats.
