Ross will be called up to start Tuesday's game against the Mariners, Jamal Collier of MLB.com reports.
EDGE Analysis
Ross has been working out kinks in delivery during his time in the minors, and although he's allowed 11 earned runs in 18 innings (5.50 ERA) since his most recent demotion, the Nationals are seemingly content with the mechanical adjustments he's made in that time. He'll jump into the rotation spot Jacob Turner was inhabiting in order to take on Christian Bergman on Tuesday.
