Roki Sasaki

data as of June 3, 2026·week 10

Sasaki is a sell — his xERA keeps climbing and it's real.

His expected ERA has been climbing across the sample and now sits at 4.59, nearly half a run above league average. He has faced enough batters for that number to be trusted. The problem is contact quality: opponents barrel the ball at 11.4% and hit it hard 44.3% of the time — both well above league, on stable samples. His xwOBA allowed is .336, .021 above league. His strikeout rate is only slightly above league at 22.5%, and his walk rate is 8.6%, a touch high. There is no luck story to lean on; his ERA tracks closely with his xERA. The skill is below league and the surface is not hiding it. Sell.
