ST. PETERSBURG, Fla. - Evidence to the contrary, Joe Girardi said Andrew Miller still isn't officially his closer.

"He's done the job every time we've put him out there," Girardi said of Miller, who is 4-for-4 in saves after securing Sunday's 5-3 victory over the Rays with a scoreless ninth.

Dellin Betances pitched 12/3 scoreless innings to set up Miller and has appeared before the lefthander every time the two have pitched in the same game.

"We're seeing a ton of righthanded hitters and we're going to see a bunch again [in Detroit], so it's kind of worked out that way," Girardi said. "And Andrew's done a good job in the ninth. I'm not saying I've named anyone, but that's just kind of the way it's worked out."

For his part, Miller hasn't lobbied for the job and consistently praises Betances, who seems to be putting his early-season troubles behind him.

"I know I've got the saves this year, but he really went through the meat of their lineup today," Miller said. "If you look at who had the heavier burden today, it was him. He came in in a much tougher situation and got more outs. I think he's throwing the ball better. Everybody's throwing the ball pretty well."

Beltran still ill

Carlos Beltran sat for a second straight day with congestion caused by a nasty cold that's been going around the club. "He still feels weak," Girardi said. "I'm really hoping to get him back tomorrow."

His replacement, Garrett Jones, went 3-for-4 with a run.
