Dooin was an outstanding defensive catcher for the Phillies during the first decade
of the 20th century. Reportedly the first to use papier-mache shin guards, he wore
them under his stockings. In 1908, he led all NL catchers in assists. That same year,
he was offered a bribe to throw a series to the Giants; he reported it. Named the
Phillies' player-manager in 1910, he suffered a broken ankle that season and a broken
leg in 1911, ending his days as a regular. He shepherded the Phillies to second place
in 1913. A fine singer, he performed with the Dumont Minstrels in Philadelphia.
