Diaz picked up the save Thursday against Houston, striking out one without allowing any hits or walks.
Diaz pitched a perfect ninth inning to earn his first save since Aug. 13, ending a streak of eight straight appearances without a save. The 27-year-old pitched to a 7.36 ERA over those prior eight outings, but he's now pitched clean innings in back-to-back appearances. With his 25th save of the season, Diaz becomes the sixth reliever with 25 or more saves in each of the last two seasons.
