Jones had a huge year in 1879, totaling an MLB-best nine home runs to go with 85 runs scored, 62 RBIs and 29 walks in 83 games, all league bests. He would set a new career high for homers in ’83, with 10, though that came during Chester Arthur’s presidency. Hines won the Triple Crown in ’78, when he hit .358 with four home runs and 50 RBIs for the Providence Grays. He led baseball with a .357 batting average the following year, and his career high of 10 homers came in ’87 with the Washington Nationals. A big 1880 season with the Boston Red Stockings helped O’Rourke, a Hall of Famer, finish tied for second during this period.
