Dreyer is a buy — the strikeout and xERA gains are earned

His expected ERA is 3.52, more than a half-run below the league average of 4.10, and he has faced enough batters for that number to be reliable. The thing driving it is the strikeout rate: 28% of batters, six points above league, and that number stabilizes at roughly 70 batters faced. His swinging-strike rate is 13.6% against an 11% league mark and his chase rate is 32.2%, so the misses are coming from the pitches, not the scorekeeping. Where he is ordinary is contact quality allowed: a 41.7% hard-hit rate and a 7.4% barrel rate are both within a point of league. That does not undo the profile — the whiffs and the 3.52 expected ERA carry the run prevention. The xERA has been stepping down as the sample grew, which is the shape you want from a pitcher whose results are following the skill. Buy. A 3.52 ERA and 1.24 WHIP with no saves is a deep-league asset — add him only where you need the ratio help.
