Hoffman is a buy — the strikeouts are real and earned

His expected ERA is 3.44, well below the league average of 4.10, and he has faced enough batters for that number to be reliable. The skill backing it is a 34.3% strikeout rate — more than twelve points above league — and an 18.7% swinging-strike rate that would stand out in any bullpen. He does it with a 96.4 mph fastball, above the league average, and the pitch has been ticking up across the season. His expected wOBA allowed is .288, so the contact he gives up is soft as well as rare. The 9.0% barrel rate is slightly above league, and his walk rate is a touch high, but those are the only soft spots in an otherwise clean profile. The velocity gains over the sample make this more than a park-aided stretch. Buy. With a 7 K / 3.44 ERA / 1.23 WHIP line, this is a deep-league asset to acquire now, not a streamer.
