"I don't know too many people who are into baseball, but I used to chat to Kasey Keller at Spurs, who is into the Seattle Mariners. He called me the other day to rub in a Yankees defeat."
Perry has subscriptions to a cable channel and an internet service to supply him with his weekly fix, but he discovered baseball by accident.
"When I was at Wimbledon, I lived near the training ground and went to bed late and got up late. I caught a baseball game when I was surfing the TV channels and got hooked.
"The Yankees won and became my team, but they are probably the most hated in the sport."
Perry compares them with Manchester United in the Premiership, but tonight he will have his eye on another team disliked by Charlton fans.
He says their feelings against Crystal Palace are strong after their ground-share from 1985 to 1991 and, as someone who was brought up a Wimbledon fan and player, he can understand why.
"There is an extra edge because they were Charlton's landlords at Selhurst Park for a time," he said.
"I think it is similar to Wimbledon, when we played there. They were a team I really wanted to beat. The Charlton fans probably feel the same and don't like them very much.
"They will be expecting us to wear our hearts on our sleeves and it should be a good atmosphere."
Charlton have no new injuries for tonight's game and manager Alan Curbishley is not expected to make wholesale changes. Francis Jeffers could be restored to the starting line-up after impressing since recovering from a neck injury.
Palace are set to rest Andy Johnson (ankle), Fitz Hall (knee) and Michael Hughes (hamstring), but Danny Butterfield (hamstring) is back and strikers Ivan Kaviedes, Dougie Freedman and Sandor Torghelle are all in contention.
