Dave Robertson, the Yankees’ bullpen strikeout specialist, said he was not worried about the tightness in his right elbow. But the Yankees have shut him down indefinitely, and he has an appointment Thursday with Dr. James Andrews, probably in Pensacola, Fla.

“The stiffness has not went away in the last 10 days or two weeks,” Manager Joe Girardi said. “It’s a concern of mine, because he’s been a huge part of our bullpen, and his ability to get a strikeout is important. He’s been as good as anyone in baseball, really, at doing that.”

“I feel confident it’s not going to be anything,” Robertson said. “I feel like I’m going to come back. It’s just a little rest.”

Robertson has not pitched on consecutive days since Aug. 11 and 12. He said he had felt discomfort for about two weeks, mostly after he pitched. He had a magnetic resonance imaging test Monday but said he did not know what it showed.

“No idea, really,” he said. “I’ll just go to Dr. Andrews and get his opinion. That’s really all I can do.”

Robertson, 24, has worked his way into a more prominent role as the season has gone on, appearing more often when the Yankees have a lead. Girardi said he was still hopeful that Robertson could return.

“I don’t want to write him off,” Girardi said. “He’s down until he sees Dr. Andrews and we figure out what we need to do. Whether he’s here or not, guys are still going to feel pressure. One thing it does is it gives you less weapons. We don’t necessarily have as much flexibility as we did.”

Maybe the Yankees should have something like the Robertson Rules in place, to prevent this? Yes, I’m kidding – sorta/kinda.
