A baseball tournament involving Challenger Baseball teams from the area will start at 9 a.m. At 11 a.m., the opening ceremony and parade of athletes will take place, emceed by Eddie Palladino, Boston Celtics announcer. Gerry Agganis will throw out the first pitch.

Nancy Kerrigan, a former Olympic medalist, will take part in the opening ceremony and will be available to meet and greet those in attendance. Other former Olympic medalists, including athletes who competed in this year’s Winter Olympics, have also been invited. The Olympic athletes will be honored during the opening ceremony.

Entertainment will start on the stage at 10 a.m. and will be provided by the Saugus High Chorus, the MemoryLaners featuring Howie “Sachmo” Conley, Beat ConnXtionz dancers, Just The Tree of Us, the Rosa Singers, and Joey B-Bop.

The whole day will take on a festival atmosphere that will include raffles, a moon-bounce, classic cars, booths, games, a hayride, costumed characters, and a large variety of food and drink. The event is free and open to the public. The rain date will be the next day, Sunday, Sept. 27.
