Call if the Fenway Flu—or, since they're on the road, Texas Trichinosis. Anyway, slumping Daniel Nava has been placed on the 15-day "disabled" list. No particular injury. No particular reason—other than a dramatic drop-off in performance. So far this year, the 32-year old Nava is hitting just .159 in 27 games. Partly a victim of the crowded outfield, Nava has had fewer chances to prove his worth this year than in the past. Neverthless, the acquisition of the immortal Carlos Peguero from Texas may have signalled the end for Nava. Stay tuned.
