Kilian is a buy — the strikeouts and the fastball are both real.

His expected ERA is 3.57, more than half a run below the league average of 4.10, and he has faced enough batters for that number to be reliable. The velocity behind it is climbing: 96.8 mph on the fastball, nearly three ticks above league, and holding as the sample grows. That heat shows up in the strikeouts, 26.8% of batters against a 22% league rate, and in a 13.6% swinging-strike rate. He is getting hitters to chase 32.7% of the time, well above league, so the whiffs aren't an accident. The one crack is the walks, 10.5% against 8%, and that rate has cleared its stabilization point. The contact he allows is soft enough — 34.9% hard-hit against a 40% league mark — that the expected ERA keeps falling. The stuff is carrying this. Buy. Deep-league asset: 3.57 ERA and 1.32 WHIP with zero saves is a streamer's line, but the stuff says stash him now.
