Diaz picked up the save after allowing one walk in a scoreless ninth inning Monday against the Braves.
Diaz issued a walk to Freddie Freeman with one out in the ninth inning, but he was able to quickly retire the next two batters to nail down the save. The right-hander is a perfect 6-for-6 in save situations this season despite an unimpressive 3.86 ERA across 16.1 innings.
