Houser is a sell — stable skill sits below league and nothing is unlucky.

His expected ERA is 4.91, .81 above the league average of 4.1, and he has faced enough batters for that number to be reliable. Nothing about it is bad luck: he strikes out 16% of batters, well below league average, and that rate has been stepping down across the sample and now sits below his career baseline of 18%. His expected wOBA allowed is .339, above the .315 league mark. He throws hard at 95.7 mph, but the fastball has not bought him swings or misses — an 8.4% swinging-strike rate trails the 11% league rate — so there is no strikeout upside hiding underneath the surface. There is no luck story to fall back on; this is the level he's at. Sell. 8 K and a 4.63 ERA ROS is a drop — waiver-wire drag, streaming-only, not a hold.
