The right-handed Betances ground his way through the heart of the Rays’ order for five outs before the left-handed Miller — after a leadoff double in the ninth — struck out three straight hitters to earn his fourth save in four opportunities.

Neither has allowed an earned run this season.

“I’ve just kind of stuck with it right now,” Girardi said of the bullpen arrangement. “I’m not saying I’ve named anyone, but it’s just kind of the way it’s worked out.”

For nearly two decades, the Yankees have had little to worry about in closing games, mostly because of Mariano Rivera but also because of John Wetteland before him and David Robertson last season after Rivera retired.

The intrigue about the role this season arose because neither Betances nor Miller — top-shelf setup men — had ever been asked to close games regularly. Each had one career save.

“Honestly, I don’t think either of us have left the roles we were used in last year,” said Miller, whom the Yankees signed as a free agent to a four-year, $36 million contract. “I’ve gotten the saves, but he went through the meat of the lineup today. If you look at who had the heavier burden today, it was probably him. He came in in a much tougher situation. He got more outs and had to face the middle of that lineup.”
