I mean, i get that Zimmer's bat has been worse than total crap, but there's no denying that him in the field, especially in Fenway would not be 1000 times better than Tapia. I'd stick Zim in CF, hit him 9th and take the L from his spot on offense rather than watching the ineviteble clusterf*** of Tapia in CF at the worst possible moment.
Or, put Teo in CF, Biggio in Left, Gurriel in RF - better offensive floor, better defense (though still not great admittedly).
