Frank Octavius Mancuso (May 23, 1918 – August 4, 2007) was an American professional baseball player and, served as a Houston City Council member for 30 years after his sports career had ended.

Born in Houston, Texas, Mancuso began playing baseball in 1937 in the minor league system of the New York Giants.

That disappointment was offset by the opportunity he had to warm up pitcher Carl Hubbell, and sharing the company of other great Giants like OF Mel Ott and manager Bill Terry.

After hitting .300 or more in three minor league seasons, Mancuso entered the U.S. Army as a paratrooper at Fort Benning, Georgia in December 1942 and was on his way to an accident that forever altered the course of his baseball career.

The Browns lost to the St. Louis Cardinals in the 1944 World Series in six games, but Mancuso hit .667 (2-for-3) and collected one RBI in injury-limited pinch-hitting duty.

In the late 1990s, Harris County built the Frank Mancuso Sports Complex, a facility that strategically reaches out to the needs of inner city kids, in his honor.
