Abner Frank Dalrymple (September 9, 1857 – January 25, 1939) was an American left fielder in Major League Baseball who hit 43 home runs (including 22 in 1884, the second-highest total to that date) and batted .288 with 407 RBI during his 12-season career spent primarily with the Chicago White Stockings.

[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.

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.

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).
