Medina is a hold — average results hide a two-way split

His expected ERA is 4.00, essentially the league average of 4.10, and he has faced enough batters for that number to be reliable. Nothing unstable is pulling it in either direction: his expected wOBA allowed is .309 and his hard-hit rate allowed is 39.2%, both right at league. But the components point in opposite directions. He strikes out 28.7% of batters, well above the 22% league rate, and his fastball sits at 97.7 mph. He also walks 12.2%, far above the 8% league mark. Elite stuff with a walk problem is not the same pitcher as a truly average one, yet the run prevention lands in the middle. His expected ERA has stepped down across the sample, which is the only lean here. Hold. 5 K and a 3.90 ERA is streaming-only noise — a drop-tier arm offers no 5x5 edge, so hold costs nothing.
