John Gibson Clarkson (1861-1909) won 328 games, won the triple crown in 1889 and twice pitched more than 600 innings in a season. In 1885, John appeared in 70 games, threw 68 complete games, 623 innings, won 53, had an ERA of 1.85, a no-hitter, and won the pennant. Apparently having to hurl the sphere a mere fifty feet was a tonic to the arm. But unlike so many pitchers of his era, Clarkson didn’t flame out from such prodigious labor on the mound. From 1885-92 he AVERAGED 36 wins per season and would win 30+ an extraordinary six times. This great career began with the Worcester Ruby Legs in 1882, flowered with Cap Anson’s Sox in ‘84 and fully bloomed in Boston when John followed his ace catcher King Kelly to the Beaneaters in ‘88. League politics that culminated in the Players’ League revolt took a toll on Clarkson’s reputation and sundered his friendship with Kelly as the hurler remained loyal to the Nationals.
- Cleveland acquired John in 1892 allowing him to team with Cy Young. Chief Zimmer, who caught Young for a decade, proclaimed Clarkson the best he ever saw
