Gasser is a hold — average across the board, nothing unstable.

His expected ERA is 4.17, a hair above the league average of 4.10, and he has faced enough batters for that number to be reliable. His expected wOBA allowed is .315, exactly league average, so there is no contact-suppression edge to buy and no alarm to sell. The rate stats confirm the picture: he strikes out 22% of batters, walks 7.1%, and gets swings and misses on 11.2% of pitches, all essentially league average. His xERA has stepped up across the sample, which is worth watching, but it has settled near the league line rather than climbing past it. There is no luck stat dragging the surface one way or the other. This is what a league-average arm looks like. Hold. 8 K and a 4.15 ERA the rest of the way: waiver-wire filler, deep-league streamer only — no reason to add or stash.
