Ashby is a buy — the strikeout stuff is real and the run prevention is earned.

His expected ERA is 2.99, more than a full run below the league average of 4.10, and he has faced enough batters for that number to be reliable. Nothing in his profile is inflating it: his xwOBA allowed is .268 against a league average of .315. The swing-and-miss is doing the work — he strikes out 30.3% of batters and gets a 13.0% swinging-strike rate, both well above league. The fastball has stepped up through the sample to 97.3 mph, and the xERA has stepped down as the velocity climbed. He does walk 10.7% of hitters, which is a real drag and a legit caveat. But the strikeouts, the weak contact, and the velocity all point the same direction, and he has the workload for the numbers to hold. Buy. Deep-league asset: 0 K / 2.99 ERA / 1.30 WHIP won't win a category alone, but acquire now before the velocity shows up in the box score.
