ROSK 9ERA 4.12WHIP 1.38W 0–1SV 0–1

Alvarez is a hold — league average, and the sample says so.

His expected ERA is 4.35, 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 .321, right around league, and his strikeout rate, swing-and-miss rate, and chase rate all sit within a point of average. There is one thing trending the wrong way: his xERA has stepped up across the sample, which keeps him from being a quiet buy. The walk rate is 10.7%, about three points above league, and that is the part of his game worth watching. Nothing here is unstable enough to sell and nothing is good enough to buy. Hold. 9 K with a 4.12 ERA and 1.38 WHIP is a drop-tier drag — hold only as a deep-league streamer, not a roster asset.
