Dalrymple started his major league career in 1878 with the National League's Milwaukee Grays, and that season, he had a career-high .354 batting average.[1] He spent the next eight seasons with the Chicago White Stockings, for whom he starred as the leadoff hitter on five NL pennant winners. In 1880, Dalrymple led the league in hits (126) and runs scored (91). In 1881, he became the first batter known to be given an intentional walk with the bases loaded. He hit four doubles in a game in 1883, which still ties him for the major league record. In 1884, aided by the short right field fence at his home park, Dalrymple hit a career-high 22 home runs and moved into sixth place on the all-time home run list. On the strength of 11 home runs for the 1885 champions, he moved up one place. For the remainder of his career, he hit only six home runs. His hitting declined in 1886, and his major league career ended five years later.
Dalrymple is sometimes cited as one of only three players in MLB history to win a batting title during his rookie season, a feat which he accomplished in 1878. (The other two were Tony Oliva, in 1964, and Ichiro, in 2001.) However, Dalrymple's claim to leading the league in hitting in 1878 has since been disputed–– even though the National League initially awarded him the batting crown for that year, further research has suggested that Paul Hines actually had a higher batting average that season (.358 to Dalrymple's .354), once one accounts for hits that were made in tie ballgames (at the time, statistics from tie games weren't counted).[2]
