Peters is a sell-high — BABIP is inflating his line.

His actual wOBA sits at .361, but the building blocks say the surface is not the real story. The gap is his BABIP of .354, 59 points above the league average of .295 — and BABIP needs around 800 balls in play to be reliable. He has 205. That gap is luck, not skill. His expected wOBA is .308, just below league average, and his xwOBA has been stepping down across the sample. His contact quality is also below league: exit velocity of 87.2 mph against an 89.0 league average, hard-hit rate of 30.9% versus 40.0%, and barrel rate of 4.9% versus 8.0%. The underlying numbers paint a clear picture: the skill does not support the production. Sell high. 2 HR / 18 R / 14 RBI / 4 SB / .264 AVG — a deep-league sell-high window, not a keeper.
