De Los Santos is a buy — earned run prevention, no luck involved.

His expected ERA is 3.27 — 0.83 below the league average of 4.10 — and he has faced 277 batters, past the point where that number becomes reliable. Nothing on his line is being propped up. He strikes out 22% of batters, walks only 6.5% against a league average of 8%, and gets swings on 14.6% of pitches, well above league. His expected wOBA allowed is .281, 34 points better than league, and he has enough batters faced to trust it. The fastball is sitting at 95.1 mph, above league, and both his xERA and his velocity have been heading the right direction across the sample. The contact suppression is real, the sample is large enough to believe it, and there is no luck hiding underneath. Buy. Just 1-1 SV and 5 K ROS, so deep-league only — but that 3.27 ERA makes him a worthy stash.
