Isbel is a sell — the bat is below league and it is not bad luck.

His expected wOBA is .260 against a league average of .315, and with 285 plate appearances his sample is well past the point where that number becomes reliable. His expected wOBA has been stepping down across the season, so the trend line is not pointing toward a turnaround. His actual wOBA is .271, so close to his expected mark that there is no suppressed BABIP story to explain the cold line away. His contact quality is the problem: 88.2 mph average exit velocity is below league, a 32.4% hard-hit rate sits under the 40% league average, and a 2.9% barrel rate is less than half the league mark. He also walks just 5.3% of the time, below league, so he is not creating value that way either. The skill is what it is. Sell. With 0 HR / 3 R / 3 RBI / 1 SB / .209 AVG rest-of-season, he's a drop — waiver fodder, streaming-only.
