league in double plays for the second and third consecutive years. After the 1884 season, the White Stockings moved to West Side Park, and Williamson's power numbers dropped. Without the short fences, his home run total dropped to three, his doubles went down to 16, and his batting average dropped to .238, his lowest average since he became a White Stocking. Despite his low hitting numbers, he did lead the league in games played with 116, bases on balls with 75, and yet again, led his position in assists, double plays, and for the fifth and last time, fielding percentage. Chicago won the National League championship that season, and agreed to play the American Association champions, the St. Louis Browns in a seven-game "World Series". Before game one began, the players of both teams held a field day which included contests of skill, and Williamson won the long throw with a toss that traveled 400 feet, four inches. The 1885 series ended in a tie when each team won three games, and one game ended in a tie. Williamson collected two base hits in 23 at bats, for a .087 batting average, and scored one run. Beginning in 1886, Williamson switched his fielding position to shortstop, while the Chicago White Stockings again won the National League championship, their fifth in seven years. The team's success did not coincide with Williamson's slide in seasonal numbers. His batting average dropped to his career low of .216, and his strikeouts jumped up to a career high of 71, in 430 at bats, although he did finish third in bases on balls. The White Stockings met the St. Louis Browns following the season and agreed to play a best of seven "World Series" for the second consecutive year. The Browns won the series, four games to two, and Williamson's statistics for the series did not improve. In fact, they were worse than in 1885. He gathered one base hit in 18 at bats, for a .056 batting average, and scored two runs. 1887 was Williamson's second season at shortstop, his last full season in the majors, and his numbers began to climb back to what they were during the early part of his career. His batting average jumped back up to .267, hit 20 doubles, 14 triples, 73 base on balls, and nine home runs. In 1888, his batting average dipped again, this time
