Diaz picked up the save Tuesday against Chicago, allowing one walk and no hits across a scoreless ninth inning.
Diaz converted on his 14th consecutive save chance and fired his second consecutive hitless appearance. The 27-year-old has a 4.23 ERA in 38.1 innings but has generally been reliable in the ninth inning, having blown merely two saves. Diaz is one of eight closers with more than 20 saves on the season.
