Norris ran into trouble in the sixth when Ian Kinsler drew a walk and Berkman hit a one-out single. Murphy's two-out single sent Kinsler home to make it 4-1. Cruz followed with a groundball single that rolled just out of reach of diving shortstop Ronny Cedeno to score Berkman and chase Norris.
Chants of "Cruuuuuuuz" filled the stadium, indicating the large number of Rangers fans who made the 250-mile trip from Dallas. Norris was replaced by Erik Bedard, who is Houston's fifth starter, but won't be needed for a while in the rotation because of off-days.
