A durable hurler, Orth won 202 games without ever throwing a curve. Instead, The Curveless Wonder changed speeds masterfully on his fastball. For the 1899 Phillies, he led the National League with a 2.49 ERA. His control was among the best; he walked 19 in 145 innings that season, and with the 1902 Senators allowed just 40 walks in 324 innings. He fell to 10-22 in 1903, and in 1904 was traded to the New York Highlanders. There he picked up the spitball from Jack Chesbro, and in 1906 he led the AL with 27 wins, 36 complete games, and 339 innings pitched. In 1907 he lost a league-high 21 games. A fine hitter, he ranks seventh all-time among pitchers with 389 career hits. He sometimes played in the field and was used 78 times as a pinch hitter.
