Lee is a sell — skill below league, no luck to mask it.

His expected wOBA is .294, .021 below the league average of .315, and his xwOBA has been stepping down across the sample — this is not a blip. His actual wOBA is near the same mark, so there is no bad-luck story. His BABIP is normal. His plate discipline is a clear negative: he walks just 4.7% of the time against a league average of 8.5%, and chases at a 32.6% clip, four points above the league norm. His contact quality is roughly league average — exit velo and hard-hit rate right around the middle, barrel rate a tick above. The underlying stick is below average, and without any luck-driven lift, the production is what it is. Sell. 3 HR, 8 R, 13 RBI, 0 SB, .236 AVG: a streaming-only drop that won't hurt you to cut loose.
