Scott is a buy — the strikeout stuff is real and the sample proves it.

His expected ERA is 3.13, nearly a full run below the league average of 4.10, and his sample is past the point where that number becomes reliable. The skill underneath it is clear: he strikes out 31.6% of batters, well above the 22% league average, and walks just 5.7%, below the 8% league mark. Both rates have cleared their stabilization points. He gets those strikeouts with a 19.8% swinging-strike rate and a 41.3% chase rate, both far above league. His fastball sits at 96.8 mph and has been ticking up, while his expected ERA has been stepping down. Nothing here is propped up by luck. Buy. Bank the 3.13 ERA and 1.08 WHIP now — this is an asset, with 1-1 SV still coming.
