Mayer is a sell — the bat is short and nothing is hiding it

He is averaging 86.1 mph off the bat — nearly three mph below the league mark of 89.0 — and a 35.5% hard-hit rate against a 40.0% league average puts the contact quality below the line where it needs to be. His expected wOBA is .257, .058 below the league average of .315, and his sample is past the point where that number becomes reliable. His actual wOBA is .258, almost exactly the same, so there is no suppressed BABIP story to point to and no slump waiting to break. The trajectory makes it worse: his expected wOBA has been stepping down across the sample, not up. He does not strike out at a worrying rate, but plate discipline only protects an at-bat — it does not create production. The stable skill is under league and it is getting worse. Sell. The ROS line reads 0 HR / 0 R / 0 RBI / 0 SB / .000 AVG — a drop, streaming-only fringe bat.
