Rooker is a hold — the contact is real, the whiffs cap it

His expected wOBA is .312, three points under the league average of .315, and 202 plate appearances is past the point where that number becomes reliable. His actual wOBA is .294, so he has been mildly unlucky, not badly so. His contact quality is solid: 15.4% barrels against a league average of 8.0%, and a hard-hit rate of 41.9%, both on 117 batted balls, enough to trust. The problem is the swing. He strikes out 31.7% of the time, well above the 22.0% league average, and that rate is climbing as the season goes. His expected wOBA is drifting down with it. The power is real and the average is not — those two facts cancel out. Hold. 1 HR / 4 R / 6 RBI / .178 AVG is a drop-tier drag — deep-league only, stream or waive.
