I'm using OPS cause it's a quick and dirty way to show my point.
Beltran's .915 OPS was 24th in the NL last year.
2003, his OPS was .911, tied for 28th in the MLB
His last three years, he's had a much worse OPS .862 than he did on the road .915.
Park factor of Kauffman - 1.278
Park factor of Shea - 0.975
Meaning he's always hit better on the road, lifting his numbers at home for his averages. Now he's playing in a park that is even less friendly to hitters, meaning he'll have to be an absolute monster on the road all season just to equal his numbers.
All of those point to concern, from me anyway.
Teixeria and Tejada have better numbers. Teixeria is up over Beltran in every cat in 2004.
