Mangum is a sell-high — BABIP is propping up the line.

His actual wOBA is .335, but the lucky-draw BABIP of .371 is pulling it up — that is 76 points above the league average of .295, and BABIP needs around 800 balls in play to be reliable, while he has 191. His expected wOBA is .291, .044 below his surface number and .024 below league average, and the xwOBA has been stepping down across the sample. The contact quality tells the same story: 84.6 mph average exit velocity, a 27.2% hard-hit rate, and a 1.6% barrel rate, all well below league. His swinging-strike and chase rates are a tick above average, but looking at the underlying metrics the bat is simply not producing above-average outcomes. The BABIP-driven line is a mirage. Sell high. 1 HR / 21 R / 12 RBI / 10 SB / .261 AVG — a deep-league trade window, sell before the BABIP mirage fades.
