Hundreds of families, players and community members filled Waltham’s streets Sunday afternoon as the Waltham Youth Baseball parade returned, marching from MacArthur Elementary School to Lazazzero Playground.

Escorted by the Waltham Police Department, teams from across the league walked the route in full uniform, waving to spectators as they celebrated the start of the season. Players from multiple divisions — including T-ball, Rookie, Minors and Majors — took part in the annual tradition.

Mayor Jeannette A. McCarthy and several City Council members attended the event, greeting families and participants along the route. Residents lined the streets to cheer on the young athletes.

The parade concluded at Lazazzero Playground, where teams gathered on the field for a brief ceremony ahead of games scheduled later in the evening.

Organized by Waltham Youth Baseball, the parade marks the official start of the local baseball season and remains one of the city’s most anticipated spring traditions.
