+Matthew Perry Junior Tennis- Matthew Perry likes to win. Very, very much. Which is why anyone who picks up a tennis racket opposite the Friends star could be in for a serious whuppin’. Behind the net on a recent Saturday afternoon at an L.A. club, the tanned, trim actor once the No. 2-ranked junior tennis player in his hometown of Ottawa makes John McEnroe look like a lovable softie.

“Are you thirsty?” he asks his exhausted opponent, whom he handily beats six games to love. “Yes? Good. We’ll get a drink later.” And if dehydration sets in sooner? Replies Perry with a sly grin: “That’s a forfeit, my friend.”

Given Perry’s fierce forehand and blistering serve honed by daily workouts with a professional coach forfeiting might not be such a bad idea. “Sweating, running for shots, this is a world I love to be in,” says the 33-year-old star, who proved his on-court skills by returning a 107 mph serve from tennis great Andre Agassi in a recent charity match. “You can talk about walking down red carpets, flying on private planes and stuff like that,” says Perry. “But to return Agassi’s serve when he’s trying to ace you and to win the point it doesn’t get better.”

And as Perry knows too well, it can get far worse. “I’ve been through a very dark time,” he says of his four-year struggle with drug and alcohol abuse, including two stints in rehab in 1997 and 2001 and a 2000 hospitalization for alcohol-related pancreatitis.

Hooked on the painkiller Vicodin, Perry says early on he was downing an “insane number of pills” between 20 and 30 daily and later drinking “probably a quart of vodka a day.” Combined with his ’00 car crash and fluctuating weight, he was clearly a Friend in need. “It was terrifying,” says Friends executive producer Marta Kauffman, “watching someone you care about in so much pain.”
