DeLuca is a sell-high — the surface line is propped up by BABIP.

His actual wOBA is .309, right around league average, but the luck-free number tells a different story: his expected wOBA is .260, .049 below the surface, and his expected wOBA has been stepping down across the sample. The thing holding the line up is his BABIP, .316 against a league average of .295, and BABIP needs around 800 balls in play to be reliable — he has 268. That gap is not skill. The contact underneath is genuinely weak: 85.8 mph average exit velocity against a 89.0 league average, a 30.2% hard-hit rate against 40.0%, and 3.0% barrels against 8.0%. He also walks just 4.4% of the time. The production is built on a stat that will not hold. Sell high. A 0 HR / 0 R / 0 RBI / 0 SB / .000 AVG rest-of-season line prices this drop-tier arm as a deep-league streamer, not a hold.
