If you're going to use WAR as your primary 'stat' of comparison, at least use it or extrapolate it for a similar amount of plate appearances, since WAR is cumulative (unless you're trying to include how much a player is injured). The numbers you use are more misleading than Pal's use of OPS.
Sandoval is much better defensively, but just looking at offensive WAR, Francisco was 1.1 over about half a season, and Sandoval was 3.0 over full season, so edge to Sandoval, but not a big difference.
OPS+ does factor in ball parks, Sandoval was 111, and Francisco was 107, so again edge to Sandoval but not a big difference, and Francisco's would be higher against RHP, but I couldn't find that listed specifically.
I'm not trying to make a case for Francisco, but just pointing out that Pal's stats are at least worth considering, and it is wrong just to say they are meaningless and then use WAR over a disparate number of at bats to compare.
