At first he used a broken pop bottle to scuff the ball deliberately. After his teammates missed hitting the ball by as much as 12 to 18 inches in practice, Ford began employing the scuff ball during games, using a small piece of emery he carried in his glove. Throughout the season, Ford worked on various ways of concealing the pitch, which helped him strike out 189 Eastern League batters.
Ford’s solid performance in Jersey City earned him another shot with the Highlanders at the start of the 1910 season. Now armed with the emery pitch–which he continued to disguise as a special kind of spitball called the “slide ball”–Ford authored one of the finest rookie pitching seasons in baseball history. In his first major league start, Ford struck out nine batters, walked none, and shut out the Philadelphia Athletics, 1-0. By the end of the season, Ford ranked second in the league in wins (26) and tied for second in shutouts (8), while posting a brilliant 1.65 ERA, seventh best in the league. With 209 strikeouts and 70 walks, he also boasted the fourth best strikeout-to-walk ratio in the league. Ford’s 26 victories also established the American League rookie record, which still stands. Thanks in large part to Ford’s dominating performance, the Highlanders finished in second place with an 88-63 record, their best showing in four years.
Ford continued to guard the secret of his new pitch, boasting to the press that he had 14 different versions of his “spitball.” “Ford worked cleverly,” umpire Billy Evans recalled. “He had the emery paper attached to a piece of string, which was fastened to the inside of his undershirt. He had a hole in the center of his glove. At the end of each inning he would slip the emery paper under the tight-fitting undershirt, while at the start of each inning he would allow it to drop into the palm of his glove.”
In 1911 the Highlanders slumped to sixth place, but Ford continued to rank among the best pitchers in the league, posting a 22-11 mark with a 2.27 ERA. On July 24 Ford also pitched for the all-star team that played a benefit game against the Cleveland Naps in the wake of pitcher Addie Joss’s death, hurling four innings in relief of Joe Wood and Walter Johnson. Another measure of respect came the following spring, when Ty Cobb spoke to a Baseball Magazine reporter about his participation in a vaudeville tour through the South. A month of one-night stands was worse than facing Walter Johnson or Russ Ford 154 games in the season, Cobb said.
But opposing batters had a much easier time handling Ford’s deliveries in 1912, as the pitcher lost a league-high 21 games, though his 3.55 ERA was still slightly better than the league average. By the following year, the secret behind the emery pitch had also made its way around the league, and the delivery was picked up by Cleveland right-hander Cy Falkenberg, who used it to win 23 games in 1913. That year, Ford battled through a fatigued right arm to post a 12-18 record with a solid but unspectacular 2.66 ERA. In a sign of his reduced strength, Ford struck out just 72 batters in 237 innings, a distant cry from the dominance he displayed as a rookie three years earlier
When New York offered him a cut in pay in 1914, Ford moved to the new Federal League, where he went 21-6 and posted a 1.82 ERA (second best in the league) with Buffalo. Ford’s .778 winning percentage led the league, as did his 3:1 strikeout to walk ratio and his six saves. It proved to be the last great season of his career, however, as the emery ball, already illegal in the American League, was banned by FL President James Gilmore in 1915. Deprived of his signature pitch and again nursing a sore arm, Ford struggled to a 5-9 record for Buffalo before the club released him on August 28, ending his major league career.
