Diaz gave up a hit and struck out two in a scoreless ninth inning Friday to notch his 32nd save of the season in a 4-3 win over the Angels.
The young fireballer has been anything but consistent in his first full season as the Mariners' closer, but he's now converted 14 straight save opportunities over his last 18 appearances despite a 4.58 ERA, 1.25 WHIP and 5.6 BB/9 during that stretch. Diaz's 11.2 K.9 in those 17.2 innings certainly helps, of course, but he'll need to sharpen his control considerably if he hopes to join the ranks of the league's elite closers next season.
