Lee is a sell — the bat plays below league and there's no luck behind it.

His expected wOBA is .276, which is .039 below the league average of .315, and he has 560 plate appearances — well past the point where that number becomes reliable. His actual wOBA is .320, barely above league, not inflated by a hot BABIP that would have to give anything back, so there's no bad-luck story either. His expected wOBA has been stepping down across the sample, getting worse rather than better. He strikes out in 15.9% of plate appearances, well below league. That low strikeout rate, though, hasn't translated into contact quality: his hard-hit rate is 34.1%, compared to 40.0% league, barrel rate 4.1%, and average exit velocity 88.3 mph. The cleanup path is weak. The plate discipline limits the floor, but it doesn't create skill that isn't there. You're not selling the number as it is — you're selling the name. Sell. With a 0 HR / 5 R / 6 RBI / 1 SB / .208 AVG projection, he's a waiver-wire drop, not a rotational hold.
