Misiorowski is a buy — his expected ERA is elite and earned.

His expected ERA is 2.09, two full runs better than the league average of 4.10, and it has been stepping down across the sample. The strikeout rate is the foundation: 38.3% of batters, against a league average of 22.0%, with a swinging-strike rate of 19.0% that is well above the 11.0% league mark. The contact he allows is weak across the board — a .225 expected wOBA allowed, a 3.9% barrel rate, and a hard-hit rate of 33.3%, all far better than league. He also limits walks to 6.7%. The fastball is averaging 100.6 mph and climbing. Nothing here is propped up by luck. The skill is real and the sample is large enough to trust it. Buy. 20 K and a 2.09 ERA ROS make him an asset — acquire before the strikeout rate pushes his price up.
