Reed Johnson gets his first start Tuesday. The Astros are starting lefty Wandy Rodriguez but Lou Piniella didn’t make many tweaks in the Cubs lineup. Ryan Theriot will bat second behind LF Alfonso Soriano, then 1B Derrek Lee, RF Milton Bradley, 3B Aramis Ramirez, CF Johnson, C Geovany Soto, 2B Mike Fontenot and P Ryan Dempster. Fontenot hit .333 against lefties last year and had three hits on Monday in the 4-2 win over the Astros.
