Mariano Yenko

Colonel Mariano Yenko was the second commissioner of the Philippine Basketball Association. He served as the Assistant Executive Secretary under Philippine President Ramon Magsaysay and as Philippine Airlines' Vice-President Corporate Secretary. The Ateneo de Manila University's Audio-Visual Room at the Moro Lorenzo Sports Complex was named after him. His son Ignatius Yenko served as PBA's Chairman and as PLDT's First Vice President.

PBA Commissioner
Mariano Yenko became the second PBA commissioner and under his term the PBA entered its second phase, the post-EDSA era after the disbandment of Crispa-Toyota. Yenko managed to turn around the league's fortunes by popularizing the Ginebra San Miguel team during his tenure. Revenue stayed strong and the PBA welcomed new legends such as Allan Caidic to carry the new generation.
