Judge is now one shy of the American League record after yet another homer in the Yankees' 9-8 win over the Pittsburgh Pirates.
The Yankees were 8-4 down heading to the bottom of the ninth, but the team's superstar outfielder turned the game on its head with a homer on a 3-1 count.
That set the stage for a stunning revival, which was complete with Giancarlo Stanton's walkoff grand slam.
The Yankees became the first team in MLB history to have a player reach 60 home runs and a player hit a walkoff grand slam in the same season – and Judge and Stanton achieved the feat in the same inning.
"I think there's something to be said for that kind of igniting," Boone said of Judge's hit.
"In a game we're down four runs, igniting some kind of magical spark that kind of went tonight in that inning. That was a special one."
But Judge, who already held the AL record for the most homers by a right-hander, is staying focused with further milestones and a pennant to chase.
"I don't think about the numbers," he said.
"When you talk about [Babe] Ruth and [Roger] Maris and [Mickey] Mantle and all these Yankees greats that did so many great things in this game, you never imagine as a kid being mentioned with them.
"It's an incredible honour. It's something I don't take lightly at all. But we're not done.
"We still have a couple games left in this season and hopefully a couple of more wins come with them.
"I'm trying to enjoy it all, soak it all in, but I know I still have a job to do out on the field every single day, and I just have to keep my head down, keep preparing and stay mentally focused."
This approach has amazed Stanton, who added: "He hit 60 tonight, and it's like nothing happened.
"He's got more work to do, and that's the mindset, and that's how it will always be. It's fun to be a part of."
