The Grafton Lake Sox Baseball Club was a summer baseball team for players from ages 15 - 19. The L'Sox were members of the Paul N. Johnson Baseball League of Worcester, Massachusetts since 1997. After a 15 year run, the orginal team disolved at the conclusion of the 2011 season, with a new team starting up in 2012.
The Lake Sox & the PNJ league provided area players with an excellent opportunity to hone individual and team skills while playing in a very competitive league. The quality of play was comparable to legion baseball, without the typical seven-day commitment required by legion ball.
