Over at the FanGraphs community blog I wrote about Marlins starter Elieser Hernandez and why he has a chance to get out from under the shadow of his Rule 5 draft status:
“After a disappointing 2018 season, Hernandez improved drastically. His minor league strikeout rate jumped to 34.3% while his walk rate fell to 6.9%. After a callup in June, he showed similar improvements, boosting his MLB strikeout rate to 24.1% and enjoying a walk rate of 7.4%.”
What changed? Find out in my article.
