Chisholm is a sell — the surface line is hiding a weaker bat

His actual wOBA is .313, essentially league average, but his expected wOBA is .296 — .019 below the league average of .315 — and his sample is well past the point where that number becomes reliable. The gap matters because expected wOBA is the skill and actual wOBA is the outcome. Both his expected wOBA and his strikeout rate have been moving the wrong way across the season: the skill has stepped down and the strikeouts have stepped up, now at 29.4% against a league average of 22%. His walk rate of 10.4% and a swinging-strike rate of 14.1% point at a hitter who is surviving on contact he cannot repeat at this rate. The underlying skill is below league and nothing in the profile is holding the line up. Sell. Projected 1 HR / 5 R / 4 RBI / 3 SB / .210 AVG — a counting-only drag, drop or streaming-only until the bat shows it.
