Great turnout at the M&M Alternators & Batteries Soccer Tournament ⚽

Our first time putting something like this together—multiple divisions, thousands in prizes, and a lot of talent on the field.

Big thanks to PlebesFC for helping make it happen.

Giving back to the community has always been part of who we are—and seeing those kids smile makes it all worth it.

Appreciate everyone who showed up and supported 🙌
