Dunning is an option to make a spot start Saturday versus the Red Sox, Shawn McFarland of The Dallas Morning News reports.

EDGE Analysis

McFarland lists Dunning and Cody Bradford as the most logical options to make the start and the decision could hinge on whether either of them are needed in relief Friday. Whoever makes the start is likely to return to the bullpen after, as Tyler Mahle (elbow) is due to return next week. Dunning has made two relief appearances since returning from a shoulder injury last week, allowing four runs over 4.1 innings.
