From Gregor Chisolm's article:
Of Walker's 6,907 career at bats, less than 1/3 came at Coors Field and in the ones that didn't he posted an .873 OPS, ahead of Campanella, Honus Wagner, Brett, Rice and Gwynn. In his MVP year he hit .366 with 49 HRs, 130 RBIs. But his numbers were better on the road. In 78 games at Coors Field he had an OPS of 1.169 while in 75 road games, it was 1.176.
Compared to Jeter, Walker holds a career edge in WAR (72.7 vs. 72.4), batting average (.313 vs. .310), on-base percentage and 7 Gold Gloves vs. 5 for Jeter.
Congrats to the very worthy Larry Walker.
