Gray is a buy — his run prevention is earned, not lucky

His expected ERA is 3.49, well below the league average of 4.10, and he has faced enough batters for that number to be reliable. The skill metrics back it up: his expected wOBA allowed is .290, .025 better than league, and his strikeout rate of 23.8% and walk rate of 6.6% are both on the right side of average. He is missing bats at a 12.5% swinging-strike rate and keeping hard contact down, with a 33.7% hard-hit rate allowed that is well below the league's 40%. His xERA has stepped down across the sample, which says the run prevention is getting sharper, not softer. Nothing here is propped up by luck. Buy. 5 K and a 3.49 ERA over the ROS make him a deep-league asset — add now before the window closes.
