Nicky and Dave Stickball Tournament

From 10 a.m. throughout the day, Kelly Park in Somerville hosts the Nicky and Dave Stickball Tournament in honor of the late David Martini and Nicholas Peters, two Somerville friends. It's too late to register to play in the games, but it's free to watch and tournament organizers are hoping for a solid group of spectators. There will be food for sale and a raffle with prizes that include tickets to see Neil Diamond at Fenway Park. All proceeds from the event go to a scholarship fund for student-athletes at Somerville High School. 10 a.m. Free. Kelly Park, Craigie and Summer streets, Somerville.
