Miguel Amaya
Amaya is a sell-high — his BABIP is carrying a line his bat can't.
His actual wOBA is .321, which sits just above league average and looks like a useful season. The number underneath it does not agree. His expected wOBA is .289, .032 below the surface, and his expected wOBA has been stepping down across the sample — the skill is trending the wrong way while the results hold up. The reason the line holds up is his BABIP: .315 against a league average of .295, on 137 balls in play. BABIP needs around 800 balls in play to be reliable, so at 137 that gap is luck, not a skill he has added. His contact quality backs that up — 87.6 mph average exit velocity, a 34.3% hard-hit rate, and 6.6% barrels, all below league. He is a catcher with a real batting line and no stable skill beneath it. The regression is coming. Sell high.
