Diaz earned the save in Tuesday's 6-5 win over Atlanta, allowing one hit while striking out two in a scoreless ninth inning.
Atlanta made things interesting in the ninth with a two-out single followed by a stolen base. However, Diaz proceeded to strike out Michael Harris, stranding the tying run on second to lock down his 28th save this season. The 27-year-old Diaz has now delivered seven straight scoreless appearances (seven innings), allowing just one hit while striking out seven in that span. His ERA is down to 4.14 on the year with a 1.27 WHIP and 54:28 K:BB across 54.1 innings.
