Young flew out to right field on the next pitch to end the game.
"Well it was a foul ball. It went before the pole, curved. It was definitely a foul ball," Leyland said. "The umpires, I really appreciate them looking at it. These games are huge, obviously, and they really did a good job of doing that. You can't ask them to do it. They did it on their own, and the right results came out of it. It was not a home run.
"It's funny how different eyes work different. Some guys thought it was definitely fair and other guys said it was foul. It actually curved before the pole and went foul, so it was definitely a foul ball."
Young said he had no idea whether the ball was fair or foul, as he was running at the time. He said he didn't look at it.
"That's what replay's for," Young said. "I couldn't tell."
The man giving chase, Royals right fielder Jeff Francoeur, clearly saw it.
"I blew it foul there at the end," Francoeur said. "It was an inch, two inches. It was right there. The only thing that brought me comfort was that I was right there and saw it. I knew it wasn't fair.
"You know what, it's good that they did review, but I knew it just missed. I was just standing there, just looking at it and honestly I was just waiting to hear the 'dink' and when I didn't hear it, I was like, 'Thank God.'"
Francoeur had plans if the call was reversed, too.
"If they would have called it fair, I was straight George Brett, running in and going ape," said Francoeur, referring to the infamous Pine Tar Game.
