The Yankees optioned Rodriguez to Triple-A Scranton/Wilkes-Barre following Sunday's 4-1 loss to the Reds.
Rodriguez was called up to make a spot start Sunday, and he was handed his second loss of the season after tossing four innings and allowing three runs on four hits and two walks while striking out four. The 22-year-old will head back to the minors while the Yankees scale back to a five-man rotation during the upcoming week.
