When Jim Rice hit the Hall of Fame ballot after his 16-year career with the Red Sox, the debates got ugly. Rice was feared, argued his supporters; Rice was overrated, a beneficiary of Fenway Park, argued his detractors. During most of Rice’s career in Boston, Fenway was a terrific hitter’s park, the traditional Fenway of “no lead is safe” lore. Overall, Rice hit .320 with 208 home runs at Fenway but .277 with 174 home runs on the road. In his 1978 MVP season, Rice hit .361/.416/.690 with 28 home runs at home and .269/.325/.512 with 18 home runs on the road. The debates lasted until Rice’s 15th and final year on the ballot when he made it in.
Through 1961, Koufax was 54-53 in his career with a 3.94 ERA, a talented but erratic left-hander. Suddenly, in 1962, he put it all together, and over his final five seasons in the majors went 111-34 with a 1.95 ERA, leading the NL in ERA all five seasons. Koufax’s control did improve dramatically, but something else happened in 1962: The Dodgers moved out of the L.A. Coliseum and into Dodger Stadium. In 1961, Koufax had a 2.77 ERA on the road … but 4.22 at home. In 1960, he had 3.00 ERA on the road … but 5.27 at home. In 1962, Koufax had a 3.53 ERA on the road … but 1.75 at home. In 1963, he was 2.31 on the road … and 1.38 at home. He had always been pretty good on the road, but the difference was he became unhittable at Dodger Stadium.
