James Otis Crandall (October 8, 1887 – August 17, 1951) was an American right-handed pitcher and second baseman.

Consequently, he was given the nickname Doc by Damon Runyon who said Crandall was "the physician of the pitching emergency".

He was traded to the St. Louis Cardinals in 1913, but made only two pinch-hitting appearances for them before being sold back to the Giants 13 days later.

That same year he flirted with a no-hitter in the morning game of a double-header in Los Angeles against Salt Lake City of the Pacific Coast League.
