Diaz earned the save in Thursday's 3-2 win over the Diamondbacks, striking out two in a perfect ninth inning.
It was a much-needed outing for Diaz, who allowed four runs on a pair of home runs in his last two appearances, both losses. After surrendering a go-ahead grand slam to Corbin Carroll on Wednesday, Diaz made quick work of the Diamondbacks on Thursday, striking out Lourdes Gurriel and Josh Bell before coaxing a game-ending pop-out from Jake McCarthy. Diaz is now 15-for-21 in save chances with a 4.19 ERA, 1.09 WHIP and 56:15 K:BB across 38.2 innings this season.
