Bryce Harper added another distinction to his ridiculous rookie season, earning his second National League rookie of the month honor for his hot-hitting September and building his candidacy for the league’s Rookie of the Year Award. The 19-year-old also earned the award in May, his first full month in the majors, and became the first rookie in franchise history to win the award twice.

Harper entered September hitting .254 and showing signs of breaking out of a slump that he suffered through this summer. Then, he went on a tear, hitting .330 (35 for 106) with a .398 on-base percentage and 1.049 OPS for September. He was a catalyst atop the National lineup, drawing 11 walks and hitting seven home runs.

Harper led the majors with 26 runs scores in 28 games in September. His .651 slugging percentage was second in the majors. He lead NL rookie in home runs (seven) and hits (35) for the month.

Harper has 22 home runs of the season, two away from tying Tony Conigliaro’s record for most home runs in a season by a teenager. And he sits at 97 runs scored on the season, 14th most in the majors, despite not being called up until late April. Harper joins Nomar Garciaparra (Boston in 1997) as the only rookies in the modern era to notch at least 90 runs, nine triples, 20 home runs and 15 stolen bases.
