Melville is a candidate to start the Reds' third game of the season, MLB.com reports.
Anthony DeSclafani (oblique) and Jon Moscot (intercostal) will be unavailable for the first turn in the rotation, and the Reds appear intent on holding Alfredo Simon out to start the April 8 series opener against Pittsburgh. Thus, there's an opening for April 7, and it sounds like it's between Melville and prospect Robert Stephenson. Stephenson walked five in just three innings against the Brewers on Monday.
