LOS ANGELES — Patience is running thin for the Los Angeles Dodgers’ $69 million closer, and the boo-ers descended upon Dodger Stadium on Thursday night as the Milwaukee Brewers tacked on Edwin Díaz’s third blown save in a week.Of all the fault lines that have been revealed during this ugly stretch for baseball’s resident juggernauts, none are more troubling than the ninth inning, where Díaz’s trumpet entrance music has come to serve as the opener to jeers. Díaz inherited a two-run lead and coughed it up in a 5-4 loss to the Brewers, who slapped single after single against him and added more uncertainty to the closer position for a club vying for a third consecutive World Series title.“It’s frustrating because I know my ability,” Díaz said. “I know what I can do on the mound. To not be able to do it sucks.”Since returning from midseason elbow surgery, the three-time All-Star reliever has allowed a run in five of seven appearances. Díaz’s ERA has swelled to 11.57 in his first year in Los Angeles.As of a week ago, the Dodgers were unbeaten in the 65 games where they held a lead after eight innings. They’ve since lost two of their last five games where they’ve had a lead in the ninth, both in innings where Díaz pitched.But a change is not coming. At least not yet.“Give me another option,” manager Dave Roberts said, repeating the rhetorical question multiple times over the course of a 5-minute barrage of questions about his closer.“I can’t just say change in lower leverage,” he continued. “I have to have other options. And to be quite honest, none of those guys really are throwing the baseball great. So that’s just kind of the way it is.”
