Sleepover attendees watched the Rangers and Astros game on a giant screen brought in on a trailer, The Fort Worth Star-Telegram said.
They then were allowed on the outfield grass to lay out their sleeping bags, where they watched "The Sandlot."
The film's director, David Evans, and one of its stars, Patrick Renna, made a special appearance at the event, the Star-Telegram said.
20th Century Fox scheduled a tour of major and minor parks as part of the 20th anniversary celebration of the film.
"We thought it was a natural fit," Mary Hyink, marketing director for Fox Sports Southwest said. "The movie has a timeless, positive message."
