Janson Junk Struggles in Short Outing Against Phillies

Janson Junk allowed one earned run on five hits while striking out four over 4.2 innings in Thursday's loss to the Phillies.

Fantasy Impact

After today’s performance, Junk holds a 4.17 ERA and 1.14 WHIP with a 6-4 record across 16 starts this season. This outing marks the end of two straight quality starts and Junk's first full year in the bigs. He ends his season with a 12th percentile strikeout rate, but a 99th percentile walk rate. It's usually good for a pitcher not to allow walks, but for someone who allows as much hard contact as Junk, it's a recipe for disaster.
