Lynch was a National League
umpire known for his honesty. He was instrumental in
increasing the prestige of umpires through such actions as leaving the field rather
than continue the game in face of heavy fan abuse. He became National League
in 1910 as a compromise candidate and served until 1914. Although his tenure was
largely uneventful, his brusque manner and forthright opinions offended several club
owners and brought about his replacement.
