Orr’s 250 pounds and great strength made him one of the best power hitters of the 1880s. An able-fielding first baseman despite his heft, he played most of his eight seasons in the American Association for Jim Mutrie‘s Metropolitans and never batted below .300. In 1886 he became the first player to top 300 total bases in one season, as he recorded league highs in hits (193), triples (31), and home runs (7). In 1887 he batted .368, and was the second of three unsuccessful Met managers. Orr is one of the few 19th-century players with a lifetime slugging average over .500. In 1890, while with Brooklyn of the Players’ League, he hit .373 with 124 RBI in 107 games before suffering a paralyzing, career-ending stroke.
