The Padres activated Buehler from the paternity list Monday.
Buehler was away for the first two games of the series but will be back on the roster as the series shifts to San Diego for Game 3 on Tuesday. The veteran right-hander is a candidate to start Game 4, if needed. Buehler logged a 4.63 ERA and 131:57 K:BB over 153.2 innings covering 32 starts this season for the Padres.
