John Thoney or John Thoeny, nicknamed "Bullet Jack" (December 8, 1879 – October 24, 1948) was a reserve outfielder/infielder in Major League Baseball who played from 1902 through 1911 for the Cleveland Bronchos (1902–1903), Baltimore Orioles (1902), Washington Senators (1904), New York Highlanders (1904), and Boston Red Sox (1908–1911). Listed at 5 ft 10 in, 175 lb., Thoney batted and threw right-handed. He was born in Fort Thomas, Kentucky.
In a six-season career, Thoney was a .237 hitter (216-for-912) with three home runs and 73 RBI in 264 games, including 112 runs, 23 doubles, 12 triples and 42 stolen bases. He made 225 appearances at left field (97), center field (52), third base (31), right field (15), second base (19), and shortstop (11).
He was considered as one of the fastest base runners in the American League, earning him his moniker, "Bullet Jack". He was plagued by injuries after breaking his collarbone early in his career, which seriously limited his playing time. He played three seasons in the middle of his career with the minor league Toronto Maple Leafs in what started out as a rehabilitation stint. His trip back to the Major Leagues was earmarked when he won the Eastern League batting title in 1906 and 1907 and was traded to the Boston Red Sox.
After retirement, he worked as a guard for Brinks in the armored vehicle service for 15 years. He died at the age of 68 in Covington, Kentucky and was buried in St. Stephen Cemetery in Fort Thomas, Kentucky.
