Billy Wagner has heard all the anecdotal evidence that he’s in good shape to receive the call for Cooperstown next month and even can tell you exactly how many votes he needs to gain.

But until the former Mets closer actually receives that phone call on Jan. 24 from Jack O’Connell, the secretary/treasurer of the Baseball Writers’ Association of America who annually notifies the new Hall of Famers, he anticipates remaining jittery.

First, the numbers: Wagner received 68.1 percent of the vote last winter in his eighth year on the ballot. The magic number is 75 percent — and Wagner has this year and next (if needed) to reach that threshold before his eligibility on the BBWAA ballot expires.

“It’s 27 votes away,” Wagner told Post Sports+ this week. “Everybody in the world has told me that everybody who gets this close gets in. It’s nerve-racking. It’s exciting. It’s everything you want. Do you start thinking about the Hall of Fame speech? How do you react? It’s a very uncomfortable feeling because you don’t have control.”
