If Travis is the starting 2B, then the back-up infielder will have to play some SS, which would eliminate Izturis from that spot. Probably Goins or Kawasaki in that scenario.
Pillar, Valencia, Goins, and Navarro would be my guess with the above lineup. I still think the 0 WAR tandem of Izturis/Goins will win out over Travis, though.
