I was lucky enough to be a young Yankees fan during the same time period and wondered about the hall of famers on those teams. Some people used to assume that Bernie, Posada and Pettitte were shoe-ins, but it's looking more and more like just Jeter and Rivera.
Anyway, you're correct...The Wizard of Oz was a poor hitter as well. In fact, his OPS was .666, even worse than Vizquel's .690. His dWAR was an incredible 21.6, compared to Vizquel's 13.3.
The only other edge that Ozzie has over Vizquel is a sizable difference in stolen bases (580 to 401). My overall analysis, however, is that they both belong in Cooperstown for being veritable black holes at arguably the most difficult defensive position.
An oddity I found in Ozzie's stats...despite only striking out 589 times in 10,778 plate appearances, he sported a decidedly mediocre .337 on-base percentage (not bad in the baseball gen. pop. but as low as you're likely to find among non-power hitting hall of famers).
