Del Castillo is a sell — the bat is below league and sinking.

His expected wOBA is .258 against a league average of .315, and he has 194 plate appearances, well past the 160 where that number becomes reliable. This is not a case of a cold line hiding good contact. He is averaging 88.2 mph off the bat — below the league average of 89.0 — with a hard-hit rate of 36.2% and a barrel rate of 6.3%, both under league, across 127 batted balls, past the point where contact quality stabilizes. The expected wOBA has been stepping down across the sample. He strikes out 27.8% of the time and chases 29.7% of pitches, both above league, so the at-bats are working against him too. Nothing here says the results are coming. Sell. A 1 HR / 3 R / 6 RBI / .178 AVG rest of season is drop-worthy — deep-league streamer at best, not a hold.
