"[3] A later article made note of Clarke's pitching skills as a sophomore in 1894: "He will be remembered by Eastern college men for good work in the box his sophomore year at Williams College, when he gave Lewis a close rub for the position of 'Varsity pitcher.

'"[4] In May 1894, The New York Times reported that Clarke had been "fairly effective," except in the first inning, and hit a "beautiful home run" in a loss to Harvard.
