Bibee is a hold — average in nearly every column, and stable.

His expected ERA is 4.32, close to the league average of 4.10, and he has faced enough batters for that to be a reliable read on him. The rest of his profile sits in the same place. He allows a 39.0% hard-hit rate against a 40.0% league average, an 8.0% barrel rate exactly at league, and a .320 expected wOBA allowed against .315. His strikeout rate of 18.9% is a few points below league and his walk rate of 7.4% is a touch better, roughly canceling each other. His xERA has trended up across the sample, but not far enough to make him a sell. There is no suppressed BABIP and no bad-luck gap hiding a better pitcher underneath. Nothing here needs fixing. Hold. 12 K and a 4.24 ERA ROS is waiver-wire filler — hold, but this is a drop-tier streamer at best.
