"This is what I signed up for," Miller said. "That's what I told them all along. They asked me if I needed to be told I had a certain role or anything like that, and I told them no, and that was the truth. I've been telling you guys that all along, and that's really what it is.
"I think for me, I'm fortunate. I've got a nice contract that's going to take care of me for a while. However they see fit to use me, they can go for it. I'll do whatever they ask and give them everything I've got."
Miller, who inked a four-year, $36 million pact with the Yankees this past winter, has permitted just one hit over his first four appearances for his new club, spanning five innings. Betances endured a shaky spring and has permitted 11 baserunners in 5 1/3 innings, yet has not allowed an earned run.
"If this is him struggling, we'll take it every time, because he's putting up zeros and giving us a chance," Miller said.
The Yanks' bullpen as a whole worked spotlessly in relief of starter Adam Warren, who allowed four runs and six hits in four innings.
"They were huge. They did a phenomenal job, picked me up," Warren said. "Obviously, that we won makes me feel better about the outing. There's a lot of things I want to work on between this and the next outing, but I think they did a great job picking me up, and they've done a great job so far this year."
Esmil Rogers retired seven of eight and Justin Wilson struck out the only batter he faced, getting the ball to the tandem of Betances and Miller for the final seven outs. It's a formula that Miller wouldn't mind being a part of a few dozen more times.
"We've shown bits and pieces of it, and over the course of the season, you want to be able to put whoever in the game and trust them," Miller said. "I think we've got everybody to do that, we just need to go out there and take care of business."
