Nalbone wanted to progress in his umpiring career, so he attended the Bill McGowan School for Umpires in Washington, D.C. in 1931 and received a degree. Later he was recommended to work in the first year of the PONY League (later known as the NY-P League) in 1939. His long career on a professional basis went from 1939-1985 as he worked under NY-P League presidents Bob Stedler and Vince McNamara.
Nalbone umpired an exhibition game between the Jamestown Tigers and the Detroit Tigers and on Aug. 22, 1939, he worked the exhibition game between the Jamestown Falcons and the Pittsburgh Pirates at Celoron Park.
Nalbone was involved in the longest baseball game on record in Chautauqua County, a 23-inning County League contest between host Cherry Creek and Sherman. Harry Brosius, a 1988 Chautauqua Sports Hall of Fame selection, was the winning pitcher.
In 1938, Nalbone umpired four games in one day with three in different communities. He began with a 10 a.m. game at Allen Park following that with a 1:30 p.m. doubleheader at Poland Center and then he did a 6 p.m. game at Steamburg.
Nalbone received a commendation from President Jimmy Carter in 1980 for 50 years of continuous service as an umpire.
He was a charter member of the New York State Chapter of Umpires and in 1978 had the honor of umpiring at Cooperstown's Hall of Fame Field, the Abner Doubleday Field. Also in 1984, he received an award for 50 years of service to the Democratic party and the Jamestown Community from former Jamestown Mayor Steve Carlson and the City Democratic Committee.
Nalbone also served as a Chautauqua County Legislator and on many committees of the Board of Legislators. He also had been the District 13 official.
Nalbone was a member of the Jamestown and Area Old Timers and was a volunteer umpire for many of their games as well as the Jamestown Little League. He was a long-time president of the Chautauqua County-Grape Belt League and served beginning in 1982 on the Board of Directors of the Chautauqua Sports Hall of Fame.
Nalbone was instrumental in 1962 with the Ways and Means Committee in helping get the Resource Center started. He served as an agent to handicapped people. He volunteered his services with the Chautauqua County Nutrition Program and received a certificate of participation from the organization. Also, he had been a member of the St. John's Holy Name Society as program chairman and vice-president while serving on the St. John's Catholic Church Parish Council, having accomplished several projects. He was also a member of the Board of Directors of the Marco Polo Club.
