Diaz notched his ninth save in Monday's 6-5 win over the Rockies, recording two strikeouts in a scoreless ninth inning.
Diaz was impressive for his second consecutive save opportunity, setting down Gerardo Parra, Trevor Story and Tony Wolters on 11 pitches. The young right-hander seems to have regained the closer role and has now rattled off five straight scoreless appearances with a 7:2 K:BB over six innings during that span.
