John Emil Frisk (October 15, 1874 – January 27, 1922) was a pitcher and outfielder in Major League Baseball.

[1] After playing for semiprofessional teams,[2] he started his organized baseball career in 1898, as a pitcher.

That season, he went 14-3 with a 2.79 earned run average for the Canadian League's Hamilton Hams.

Frisk hit .313 early that season, but had a mediocre record as a pitcher and was released in July.

In 1902, he had his breakout season, batting .373 with 14 home runs and leading the league in both categories.

[5] It had been a smooth transition from pitching, but in 1903 Frisk slumped down to .273 and subsequently moved to the Pacific Coast League.

He bounced from the American Association's St. Paul Saints to the Browns in both 1906 and 1907 and played his last major league game on April 23, 1907.

[3] In 2003, baseball writer Bill James named him as the best minor league player of the 1900–1909 decade.
