Diaz gave up a hit and a walk while striking out two in a scoreless ninth inning to earn the save in a 4-1 win over the Rangers on Sunday.
Diaz allowed a couple of baserunners, but he used his power slider to strike out a pair of hitters before getting out of the inning with his 18th save of the season. His save total ties him for fifth-best in the majors and comes along with an enviable 1.95 ERA. The 28-year-old flamethrower's most impressive stat could be his strikeouts -- he has struck out 63 batters over 32.1 innings for an incredible 17.5 K/9.
