Frank already said that Sori will lead off the rest of the season. So we'd have to get rid of Frank.
Sori leads the team in steals, so if he singles, he can steal his way to 3rd base. We need to hit him in. Vidro leads the team hitting into DP's and has constantly been thrown out in dumb baserunning moves. I think I'd go Soriano-NJohnson-Zimmerman-Vento.
