DeSclafani (ankle) was activated from the 10-day injured list to start Sunday's game in Atlanta, John Shea of the San Francisco Chronicle reports.
The right-hander will rejoin the rotation Sunday after spending the 10-day minimum on the shelf with right ankle inflammation. DeSclafani has a 5.68 ERA, 1.46 WHIP and 24:7 K:BB in six starts since the All-Star break, and he'll attempt to get back on track versus Atlanta.
