New York Yankees general manager Brian Cashman admitted it’s difficult for him to gauge exactly what the team should expect out of Alex Rodriguez in the 2016 MLB season.

With Rodriguez hitting the age of 40 last August and obviously the best years of his career well-behind him, Cashman acknowledged the Yankees need to take a wait-and-see approach when projecting just how productive the designated hitter can be next season.

“Alex, at this stage of his career, you just don’t know. I didn’t know what to expect from Alex this year and he was spectacular, one of the best, most productive DHs in the game and hopefully that can give us some comfort that we’ll see that again this year,” Cashman said on YES Network’s “Yankees Hot Stove” Monday, via “But at the same time, you’ve got to acknowledge that you don’t know what you’re going to see or what you’re going to get. But I do know one thing, he’s going to be working his tail off and he’s a threat at the plate every time he’s up there.”
