Lukes is a sell-high — BABIP is inflating his line.

His actual wOBA is .331, .030 above his expected wOBA of .301, and that gap is the story. The surface number is being lifted by a BABIP of .321 against a league average of .295. BABIP needs around 800 balls in play to be reliable, and he has 170 — that gap is luck, not skill. Meanwhile, his contact quality is clearly below league: 86.7 mph exit velocity, 29.4% hard-hit rate, and a 1.2% barrel rate, all well off the league pace. His expected wOBA has been stepping down across the sample, confirming the skill is lower than the surface suggests. His strikeout and walk rates are fine, but they do not change the core issue. Regression is coming. Sell high. 1 HR, 15 R, 16 RBI, 0 SB, .270 AVG: a deep-league sell-high window — trade the luck before it closes.
