Mercado could make a spot start Sunday against the Athletics, Corey Seidman of NBC Sports Philadelphia reports.
Mercado was moved to the bullpen after being roughed up by Atlanta in his latest start, though the Phillies have since scratched Zack Wheeler (back) from Sunday's upcoming scheduled start. That could set Mercado up for a spot start heading into the All-Star break. It's also possible that Philadelphia opts for a bullpen game instead.
