Diaz was charged with first blown save of the season in Saturday's extra-innings win over the Angels, allowing a two-out, game-tying, two-run home run in the ninth inning.
All was right in the Mariners' world through the first two-thirds of the top of the ninth, with Diaz seemingly on his way to yet another save after retiring Luis Valbuena and Ian Kinsler. However, Mike Trout then laced a ground-rule double, and Justin Upton subsequently tied up the contest with a 404-foot shot that cleared the center-field fence. Diaz has now run into trouble in two of his last three appearances, allowing three earned runs across those outings.
