Washington Post columnist Tom Boswell talks about Harper today and his penchant for running into walls and brings up Pete Reiser. In 1941, Reiser hit 70 XBHs, led the league in runs scored, doubles, triples, BA, SLG, OPS, OPS+, TB, and just for good measure, HBP while finishing 2nd in MVP (to teammate Dolph Camilli). He was 22 years old. Then came the injuries, many of them as a result of running into walls. Now you could also write off the fact that he never nearly matched that '41 season or again led the league in anything (except for SB twice including one season where he sole home seven times) on later losing three seasons to WWII or on that one season being a fluke. But there was also the problem where--between minor league ball, army ball, and major league ball--he was carried off the field 11 times, nine of them not regaining consciousness until he was in the clubhouse or a hospital. He had just four full seasons in the majors, his last one at age 28. He was finished even as a part-timer by 33 and was dead by age 62.
