Strahm will serve as the Phillies' opening pitcher for Sunday's game against the Mets, Corey Seidman of NBC Sports Philadelphia reports.
Strahm will likely be asked to work the first inning or two before making way for Nick Nelson, who is expected to serve as a bulk reliever. After gathering three holds and a save over a stretch of seven appearances in which he didn't allow an earned run, Strahm surrendered two runs on three hits over one inning in his most recent relief outing Thursday against the Pirates.
