Diaz saved Sunday's 3-2 triumph over the Phillies, hitting a batter and striking out one in the ninth inning.
Diaz was called upon in the ninth to protect a one-run lead and delivered a clean outing aside from a HBP in his first save situation since last Sunday. The 27-year-old has now thrown four straight scoreless innings and appears to be back on track following a rough stretch earlier this month.
