The O’Neil Cannon softball team closed out its 2026 season after another summer of competition, camaraderie, and plenty of memorable moments.

This year’s roster brought together attorneys and staff from across the firm, including several first-time players who quickly became part of the team. From big hits and standout defensive plays to close games and comeback efforts, every player contributed throughout the season.

Just as important as what happened on the field was what happened off it. The softball season provided an opportunity for colleagues to connect outside the office, build new relationships, and enjoy time together throughout the summer. Family members, friends, and coworkers also showed up week after week to cheer on the team, creating a fun and supportive atmosphere at every game.

A special thank you to everyone who played, coached, volunteered, and supported the team this season. We also appreciate the firm’s leadership for helping make another successful season possible.

We’re already looking forward to next year.
