How is Janson Junk performing?
Janson Junk is a back-of-the-rotation starter through 20 games. His 16.6% strikeout rate and 16.2% whiff rate are modest, indicating limited swing-and-miss stuff. At 5.0 innings per start, he's working shallow into games, which caps his volume impact and limits his ability to function as a reliable workhorse. The profile depends on keeping the ball in the zone and avoiding big innings rather than overpowering hitters.
