2025 MSBL/MABL World Series · Phoenix Metro, Arizona
MBI completed a remarkable double at the 2025 MSBL World Series, claiming the 73+ National Division championship with a tightly contested 6–4 victory over the LA Athletics — just days after winning the 70+ Cactus title. The back-to-back championships in different divisions made MBI the undisputed organization of the tournament in the upper-age brackets.
The 73+ final was a close affair, with the LA Athletics competitive throughout. MBI's experience at this level — playing in the most senior division in the tournament — showed in how they managed the late innings. Holding a 6–4 lead heading to the final frames, MBI's pitching staff protected the margin against an LA lineup that had been dangerous all week.
The final out of the 73+ National championship gave MBI their second World Series title in the same tournament — a feat that underscores the extraordinary depth and organizational strength of a program built to compete and win at the highest level of senior baseball, even against players in their eighth decade.
