Hearn is expected to be stretched out to a longer role in the near future, Chris Halicke of SI.com reports.
Hearn has pitched more than two innings in a given outing twice this season, but he could be used as a long reliever going forward. The Rangers haven't said whether the southpaw will be used as a traditional starter in 2021, but he could claim a spot in the starting rotation if Kyle Gibson is traded away prior to the end of July.
