Heim is a sell — skill below league, no luck to blame.

His expected wOBA is .297, which is .018 below the league average of .315, and he has 180 plate appearances — enough for that number to be reliable. His actual wOBA tracks closely with xwOBA, so there is no luck story pulling the line down. His contact quality is consistently below league: a 29.8% hard-hit rate versus 40.0% league average, and his average exit velocity is 87.1 mph, nearly two mph below league. Barrel rate is also slightly below league at 6.9%. The xwOBA trajectory has been stepping down across the sample, reinforcing that the skill is declining. There is no hidden upside here — this is the level he's at. Sell. 3 HR / 17 R / 21 RBI / 0 SB / .220 AVG is a drop-tier line — a streaming-only catcher at best.
