One of Aaron Boone’s first priorities once he was told he got the job as Yankees manager was to contact some of his new players. “I’ve reached out to a lot already,’’ Boone said at Yankee Stadium on Wednesday. “I’ve texted with a lot of them. I’ve spoken with a handful. Obviously, I know some guys pretty well.” Perhaps the most important player on that list is Gary Sanchez, who spent his first full season in the majors continuing to put up historic offensive numbers, but also continuing to frustrate Joe Girardi, the man Boone is replacing in the dugout. Asked if he felt he needed to establish a good relationship with Sanchez quickly, Boone said he did. “I have a priority in that Gary and my relationship is important,” Boone said. “I expect it to be very strong. My expectation is that he’s going to be one of the great impact players on both sides of the ball for a long time to come. I’ve already texted back and forth with him a little bit and I expect to meet up with him at some point in the next couple of weeks.”
