and fielding average (.911) for the first time. Over five seasons with the team he gradually improved his hitting, and in 1882 he was among the league's top ten players in home runs (4), doubles (27), slugging average (.450) and total bases (161) while also leading the league in assists (311) and tying Sadie Houck's major league record of 40 double plays, set the previous year; Frank Fennelly set a new major league mark with 46 for the 1885 Cincinnati Red Stockings in the American Association. In 1883, batting third, Glasscock led the team in runs batted in, and paced the NL in fielding again with a .922 average. In mid-1884 he jumped to the Cincinnati Outlaw Reds of the Union Association during that league's only season of play and batted .419 in 38 games. He returned to the NL with the St. Louis Maroons for the next two years, becoming team captain. In 1885 he set an NL record for assists (397), breaking Arthur Irwin's 1880 mark of 339, and led the league in fielding average (.917); he also moved ahead of Davy Force to become the major league career leader in games at shortstop. In 1886 he hit .325 and was fifth in the league in doubles and sixth in hits, also breaking his own NL record with 43 double plays and again leading the NL in assists (392) and fielding (.906). The Maroons moved to Indianapolis and became the Indianapolis Hoosiers before the 1887, and Glasscock continued his solid output in Indianapolis with a .294 average that year. He also set new major league records for assists (493) and double plays (58), topping Fennelly's totals of 485 and 54 with the previous year's Red Stockings. Ollie Beard broke his major league assists mark with 537 for the 1889 Red Stockings, and Bob Allen set a new NL mark with 500 for the 1890 Philadelphia Phillies. Glasscock led the league in fielding (.901) again in 1888, and would later break his own NL double play record with 60 in 1889, though Beard set a new major league mark with 63 the same year; Allen broke the NL mark with 68 in 1890. 1889 marked Glasscock's top all-around season as he batted .352 – second in the NL behind Dan Brouthers, and the best average by a major league shortstop prior to 1893, when the pitching distance was increased
