One of the more pleasant surprises of the new television season is the CBS series "Clubhouse" — a sweet, uplifting, entertaining show about a teenager who hits a grand-slam home run when he gets a job as a bat boy for the major-league team he's rooted for all his life.

But "Clubhouse" (Tuesday, 8 p.m., Ch. 2) is not a show about baseball.

"It will all be there to move the story. It will never be baseball for baseball's sake," executive producer Daniel Cerone said. "The goal was to make Pete Young our window into this team and show a side of the game that people don't normally get to see.

"This is a show set in the world of baseball. Primarily, it's a show about a family with Pete Young (Jeremy Sumpter) at the center of it and how all these various characters influence him as he undergoes essentially a coming-of-age experience."

So when the story is about a steroids scandal or allegations of corked bats, it's really about how Pete reacts to — and grows from — those experiences.

Pete is a good kid whose single mom (Mare Winningham) has struggled to raise him and his older sister (Kirsten Storms), who, unlike her brother, is always pushing the boundaries.

There's a huge fantasy element to the show — you've got to suspend disbelief to accept that the big-time baseball hero (Dean Cain) becomes a big-brother figure to Pete, for example — but "Clubhouse" is done with such heart that, once you accept the premise, it's believable within its own universe. And it's the sort of fantasy universe that we've seen in big-screen films aimed at families.

"His home is on Staten Island because it's that suburban, Steven Spielberg-esque environment that a lot of us grew up in," Cerone said. "And there, sparkling across the bay like Oz, is New York. And we wanted to make this adventure and this journey that this kid takes as big and as epic as possible. There, frankly, is no bigger city or scarier city.

"And on top of that, we have an overprotective mother who wants to hold onto her son as he's making this huge transition into real life."

Unlike most TV teens, Pete not only looks the right age (Sumpter is 15 playing 16), but he acts the right age.

"He is the show and he changed the direction of the pilot a little bit," said Cerone, who discovered that the lines he'd written for his fictional teenager didn't sound right coming out of the mouth of a real teenager.
