After the formation of the team was announced in August 2002, Lopardo funded a massive, expensive renovation of Fraser Field.

Another highlight of the 2003 season was a game against the New Jersey Jackals in which the Spirit set over 15 Northeast League records by scoring 14 runs in one inning.

On the field, the team featured two players who were signed by Major League Baseball organizations: outfielder Carlos Sepulveda, by the Florida Marlins and second baseman Marcos Agramonte, by the San Diego Padres.

Also in that year the team held a ceremony honoring legendary North Shore baseball player Tony Conigliaro and retiring his number 25.

In 2004 the Spirit played host to 120,000 fans, breaking the record they had set the year before, and ranking third in league attendance behind the Brockton Rox and Quebec Capitales.

The team featured two more players who would be picked up by Major League Organizations, this time, two pitchers: John Kelly and Jeremy Sugarman, who were signed by the Seattle Mariners and Cincinnati Reds, respectively.

Rumors were rampant in late 2006 that the Spirit would leave Lynn, but in November the team confirmed that it would return for a fifth season at Fraser Field, set to begin on May 25, 2007.
