Mangum is a sell — below-league contact and no luck to blame.

His expected wOBA is .285, thirty points under the league average of .315, and across 479 plate appearances that number has had plenty of time to settle in. Contact quality is the reason: 86.0 mph average exit velocity, a 27.8% hard-hit rate against a league average of 40.0%, and 2.3% barrels — the sample on each is past the point where it becomes reliable. His actual wOBA of .310 tracks close enough to expected, so bad bounces are not dragging the line down. The xwOBA trend is stepping down across the sample, not up. A 5.2% walk rate against a league average of 8.5% and a 45.1% chase rate give him no way to make up the ground through on-base traffic. This is the level he is at. Sell. The ROS line reads 0 HR / 0 R / 0 RBI / 0 SB / .000 AVG — streaming-only filler, a clear drop and waiver fodder.
