Mayer is a sell — the contact is light and trending down.

His expected wOBA is .259, which is .056 below the league average of .315, and he has 228 plate appearances — well past the point where that number becomes reliable. His actual wOBA is .267, so there is no bad-luck story propping up a stronger underlying skill; the line and the skill match. The contact quality confirms it. He averages 86.1 mph off the bat, three mph below league, with a 36% hard-hit rate and 6.1% barrels, both below average on 164 batted balls. His expected wOBA has been stepping down across this sample. He does not strike out much, 19.3%, which limits how far the average can fall, but it does not add power. There is no luck to give back. Sell. 1 HR / 4 R / 3 RBI / 1 SB / .203 AVG is pure drag — fade the skill, drop or stream deep-league only.
