Mateo is a sell — below-league bat, nothing unlucky about it

His expected wOBA is .272, forty-three points below the league average of .315, and his 221 plate appearances are past the point where that number becomes reliable. There is no correction waiting: his actual wOBA of .248 sits below his expected mark, so if anything the surface is slightly worse than the skill. His contact quality confirms it — 87.3 mph average exit velocity, a 35% hard-hit rate, both under league. The swing is where it breaks down: a 31.2% strikeout rate against 22% league, a 17.7% swinging-strike rate and a 44.2% chase rate, all with stable samples. Expected wOBA is stepping down across the sample and the strikeout rate is stepping up. That is not a bat about to turn around. Sell. A 0 HR / 0 R / 0 RBI / 0 SB / .000 AVG line is pure drag — treat him as waiver-wire fodder and move on.
