Robert Frank Roth was born in Burlington, Wisconsin, on August 28, 1892. Roth's parents resided in Chicago, but vacationed in Burlington each summer at his mother's brother's house on the Fox River. Roth's brother, Frank, was 14 years older than Bobby. He was a catcher in the major leagues between 1903 and 1910.[1]
Braggo struck out often, leading the American League in strikeouts in 1917, and finishing among the leaders four other times. However, he also drew decent numbers of walks for the times, with a lifetime .367 on-base percentage. He was several times among the stolen base leaders, finishing as high as second in the league in 1918. He led the league in hit-by-pitch in 1918 and was two other times among the leaders.
Before the 1920 season, the Red Sox traded Roth and Shannon to the Washington Senators for Eddie Foster, Harry Harper, and Mike Menosky.[3] Roth had his best season of his career with the Senators, with 92 RBI. After the season, he was traded by the Senators to the New York Yankees for Duffy Lewis and George Mogridge.[4]
Roth missed a substantial portion of the 1921 season with a knee injury.[1] Before the 1922 season, Roth declared his knee fit for play,[5] but the Yankees released him due to his knee injury, which did not respond to treatment.[6] In 1923, Roth played for the Blues and St. Paul Saints, also of the American Association. He played for the Hollywood Stars of the Pacific Coast League in 1928.
