Walker picked up the save over the Padres on Saturday, allowing one hit over a scoreless ninth inning.
Walker took the mound with a three-run lead in the bottom of the ninth and surrendered a leadoff double to Fernando Tatis on the first pitch before retiring the next three batters in order to end the game and secure his sixth save of the campaign. The right-handed reliever has converted each of his six save opportunities this season and still hasn't allowed an earned run since July 27 against Colorado. Since the start of August, he's gone 2-0 with six saves while posting a 29:3 K:BB over 16 innings.
