Rodriguez (knee) is set to throw a simulated game Sunday at the Boston's spring training facility, Scott Lauber of ESPN.com reports.
Despite starting the season on the disabled list due to a patella injury, Rodriguez is making progress in his recovery and has ramped up his activity considerably over the last few days. He threw a live batting practice session Monday and the Red Sox plan to have him back on the mound for a sim game Sunday. The next logical step will be for Rodriguez to begin a rehab assignment, but he may need another simulated game or two before he starts playing in games.
