Jonathan Loáisiga

AZ·P
data as of June 3, 2026·week 10

Loáisiga is a sell-high — his ERA is BABIP luck.

His ERA sits at 2.49, but the skill metrics do not back it. The main driver is a suppressed BABIP-against of .273, 22 points below the league average of .295. BABIP-against needs around 800 balls in play to be reliable, and he has 68 — that gap is luck, not skill. Strip out the bad-luck sequencing and his expected ERA jumps to 3.55, more than a run higher. Meanwhile, his strikeout rate has stepped down across the sample and now sits at 15.1%, well below the league average of 22%, and that number is stable. There is no elite-stuff story to fall back on when the BABIP normalizes. The ERA is the market price; the underlying data says sell. Sell high.
