Harry Michael Fanok Jr. (born May 11, 1940) is a retired American professional baseball player, a right-handed pitcher who was nicknamed "The Flame Thrower" for his blazing fastball.

Fanok made 16 appearances, all in relief, for the 1963–64 St. Louis Cardinals of Major League Baseball, but he sustained a career-shortening injury to his throwing arm in August 1963 while pitching for the Triple-A Atlanta Crackers.

But Fanok allowed 21 bases on balls and 24 hits, and was told to change his customary three-quarters throwing motion to a straight overhand delivery by Cardinal manager Johnny Keane.

[1] Sent back to Triple-A Atlanta to find his rhythm, Fanok pitched well — striking out 146 batters in 127 innings[2] — and was overpowering in an exhibition game against the New York Yankees.

All told, he struck out 35 batters in 331⁄3 major league innings, allowing 29 hits and 24 walks.
