12 in 1881. He followed that season with 27 in 1882, which was fourth in the league. During this time period, when his level of hitting had dropped, his play in the field did not. He led the league in fielding percentage from 1880 to 1882, and in assists in 1881 and 1882. In 1883, Williamson set the major league record for doubles in a single season by hitting 49, surpassing King Kelly's 37 set the previous year. Williamson's record for doubles stood until Tip O'Neill of the St. Louis Browns hit 52 in 1887. Williamson's doubles achievement was attributed to the short dimensions of Chicago's Lakeshore Park; the distances were in left field, in center field, and in right field. Balls that were hit over the fence were counted as doubles until 1884, when they became home runs. On September 6, Chicago scored a record 18 runs in one inning during a 26–6 victory over the Detroit Wolverines. Williamson contributed three hits, and scored three runs in that inning, setting individual records in both categories. Other than runs scored, the other team records set that day included the most hits and total bases in one inning. During this time period, the establishment of the ground rules of each park rested with the home team. In 1884, team captain and on-field manager Cap Anson decided that balls hit over the fence were to be home runs. Williamson used these short dimensions and new ground rules to set the single-season home run record by hitting 27 in a 112-game season, surpassing the record of 14 set by Harry Stovey the previous year. Of the 27 home runs he hit that year, 25 of them were hit at home. This record stood for 35 years until it was broken in 1919 by Babe Ruth, who hit 29 for the Boston Red Sox in a 140-game schedule. The first three of Williamson's 27 home runs came on May 30, in the second game of a doubleheader against the Detroit Wolverines. Williamson became the first major league baseball player to hit three home runs in one game. During these two record-breaking seasons, his fielding prowess did not recede. He did not lead the league in fielding percentage in either 1883 or 1884, but did lead in assists, capping off a streak of five consecutive years in which he did so, while also leading the
