Arenado is a sell — the surface line outruns the bat

His expected wOBA is .300, below the league average of .315, and he has 599 plate appearances — nearly four times the sample it takes for that number to become reliable. The contact metrics back it up rather than rescue it: 85.2 mph average exit velocity against a 89.0 mph league mark, a 31.3% hard-hit rate against 40.0%, and a 7.0% barrel rate against 8.0%, all on 416 batted balls. His actual wOBA sits at .349, well above his expected figure, and the trend in that expected number has been stepping down across the sample. The strikeout and walk rates are ordinary, so nothing there explains the gap. The bat is what the contact data says it is, and the line above it is not. Sell. A 0 HR / 0 R / 0 RBI / .000 AVG projection is a waiver-wire tax, not a hold — cut him.
