Diaz tossed a perfect ninth inning with a pair of strikeouts to record the save in Thursday's win over Miami.
Diaz picked up his 28th save of the season, getting Joe Panik to fly out before whiffing Jorge Alfaro and Bryan De La Cruz. The right-hander has been on a terrific run since late July, converting nine straight save opportunities while allowing runs in just one of his 15 appearances during that stretch. He also boasts a 23:3 K:BB over 16 innings in that time.
