Dunning is expected to serve as the Rangers' primary pitcher Friday against the Angels, Jeff Wilson of RangersToday.com reports.
Dunning will take the rotation spot of Jacob deGrom (elbow), though it's unclear if he will work in a traditional starting role or behind an opener. He's thrown at least three innings in half of his eight appearances this season, though he may need to work as a bulk reliever to pitch deep enough to qualify for a win Thursday. Dunning has been impressive with a 1.77 ERA and 0.84 WHIP across 20.1 innings, though that's backed by just an 11:5 K:BB.
