Bello could be called up from Triple-A Worcester to start Wednesday's game against the Rays, Pete Abraham of The Boston Globe reports.
Bello has sparkled this season at both the Double-A and Triple-A levels, and Boston could be ready to give its top pitching prospect his first chance to show what he can do at the top level. The Red Sox currently have five starting pitchers (Nathan Eovaldi, Rich Hill, Chris Sale, James Paxton and Garrett Whitlock) on the injured list and another (Michael Wacha) who is day-to-day with an injury.
