Houser is a sell — his xERA is climbing and the strikeouts are gone.

His expected ERA is 4.95, .85 worse than league average, and it has been stepping up across the sample. That is the wrong direction for a pitcher at this point in the season. The driver is his strikeout rate: 16%, six points below league, and it is falling — his career baseline is 18% and he is now under it. A swinging-strike rate of 8.4%, against 11% league, says the whiffs are not going to come back on their own. His walk rate is fine at 7.2%. His BABIP-against tells us nothing, but here it does not need to. The contact he allows (.339 xwOBA) is above league, and there is no suppressed luck stat to blame. Sell. 0 K and a 4.65 ERA make him a drop — fringe waiver material, not a hold while the skills keep sliding.
