Take a look at the team roster and make notes on each player. Record the position he played. Note the special challenges she faced during the year, whether in a particular game or practice of just generally throughout the season.
Write one or two sentences about each player, emphasizing achievements or improvements. Emphasize a wide range of talents, not just high scoring, to celebrate each of the skills a strong team needs. Skills can include great pitching, strategy (judging when to steal, when to bunt, when to walk, etc.), and infield and outfield play.
For players who weren't strong on the field or at bat, stress improvements in skills like catching and throwing, hitting, pitching and more. You may want to use this part of the speech to highlight a particularly improved player with a Most Improved trophy or T-shirt.
For players who didn't bring strong skills to the team or improvement to their play, describe how they affected team morale just by participating. This is a great point in the speech to include funny anecdotes or stories about players who contribute in ways that don't show up on a statistics sheet but are invaluable to a strong Little League team.
Include several sentences about your gratitude to players' parents who helped out over the year. Parents may have helped with giving rides to their kids or carpooling with other families, bringing water, Gatorade or other treats to practice, working with their little players at home and coming to games to cheer. Little League teams can often be family affairs, with several siblings eventually playing on the same team. This is a great time to say whether there are families who have brought an entire slate of players to the roster over the years.
Conclude with a few sentences about what an honor it has been to work with the team, how much you appreciate the efforts of parents and players, and how much you hope to see familiar faces next season. If your team won any recent competitions or had an outstanding competitive season, mention them. If you have plaques, trophies, T-shirts or other prizes to award to your team, do so at this time. Finish off with a relaxed celebration like a pizza party or ice cream social.
