Iglesias earned the save against the Diamondbacks on Friday, firing a scoreless ninth inning while surrendering one hit.
Tasked with protecting a 4-3 lead in the ninth, Iglesias forced Carson Kelly and Ildemaro Vargas to fly out before allowing Ketel Marte to swat a double. The 29-year-old stifled any additional threat by inducing a groundout from Josh Rojas to end the game. The save was the 30th of the year for Iglesias, who has now posted back-to-back 30-save seasons.
