Career
The 5 ft 10 in (178 m), 175 pounds right-hander was a native of Sandymount, Maryland. Flater pitched in five games for the Athletics. He hurled complete games in all three of his starting assignments, and he finished two other games in relief.
He pitched much better than his 1–3 record would indicate.
In 39.1 innings he allowed only 49 baserunners (35 hits, 12 walks, and 2 hit batsmen), and just 9 of the 15 runs that scored against him were earned runs. His European Research Area was an excellent 2.06.
The games he lost were by scores of 2–1, 3–2, and 5–4. Four of his famous teammates on the Athletics were future Hall of Famers Chief Bender, Eddie Collins, Jimmy Collins, and Eddie Plank.
Flater died at the age of 87 in Westminster, Maryland, and is buried in nearby Sandymount, Maryland.
