The discussion of Larry Walker the hitter reminds me somewhat of Jim Rice discussions so even though I am not voting here until I have a chance to read the previous pages I wanted to look into it. Walker was obviously the better fielder and runner, but you do not get into the HOF on that alone as a corner OFer, I would say at least 80% of the weighting for a corner OF is based on how well they hit.
Larry Walker put up the following numbers at Coors
381/462/710/1172 with a BABIP of 390.
Elsewhere, road and at home in Montreal and St Louis his stats look like this
306/398/519/917 with a BABIP of 306
To give this some context, the OPS at Coors is higher than Barry Bonds post 1992 number (1.149) which is the best in MLB, while a 917 OPS would rank him 30th among players who played between 1993 and 2006 with at least 3000 PA, right behind Bobby Abreu and tied with Rafael Palmeiro. Most hitters hit better at home than away even in neutral parks so Larry Walker adjusted for Coors is somewhere between his unadjusted ranking of 7th and 30th. Split the difference and call it 17th (not very scientific but it is probably as accurate as most adjustments) and he is in the mix among Ken Griffey Jr, Delgado, Giambi
It was mentioned that perhaps Larry Walker numbers on the road were affected by his playing at Coors. I can see how this might be true in Fenway, as RHB would try and pull everything when they would be a better hitter not doing so, which is probably why so many LHB perform better when they come to Boston, since they go the other way more often. But at Coors, the advantage was that fly balls simply went 20 ft farther than at sea level. Of'ers have to play deeper, so more balls fall in for singles, and more fly balls balls are doubles or HR's, helping to explain Walkers much higher BABIP at Coors, so unless Walker was a GB hitter who changed his swing to hit FB's, it is hard to argue that Coors negatively affected his road numbers.
The other thing on Rice was his high strike out rate. Walker actually had a higher rate per AB, 17.8% vs 17.3%.
I know Rice is off the ballot here so am not making a case for Rice, just pointing out the concern on Walker in a bit more detail since Coors was the most extreme hitters park of all time, until the the humidor in 2002 where it is now more like Fenway during the late 70's.
Last thought. Recently I studied the effect of batting handedness among hitters. Walker of course is LHB and Rice was a RHB. We talk about the advantage that hitters have due to park, era, league, but what about players who need to face a pitcher from the same hand as they hit 70% vs 30% od the time. I looked at players who accumulated 5000 or more PA from 1920-1992 using Baseball References database. There were 486 such players (9.1% SHB, 56.6% RHB, 34.4% LHB).
Their performance on average was as follows
SHB 275/345/383/728
RHB 276/343/419/752
LHB 288/363/439/802
SHB did not seem to get much of any advantage from batting both sides of the plate, that is probably because they have 2 different swings to worry about, and most would do better choosing one side or the other.
LHB had a significantly better result than RHB, being 50 points higher on OPS. Not saying we should add 50 points of OPS or 12 points BA to every RHB to compare to a LHB, just saying it is a factor to consider between 2 players when all else else is equal, in which case you should vote right
